+
+        - The log of the run that crashed is `logs\totk.log` in the folder of `totk.exe` (F1, Advanced tab, Open log folder). Copy it before you start the game again: the next start renames it to `totk.1.log`, and after five starts it is gone.
+        - Attach the whole file. Do not cut or edit it: the crash report is at the end, the GPU and driver lines are at the start.
+        - The log says `device lost` or `VK_ERROR_DEVICE_LOST` and the GPU is an NVIDIA one: set GPU pass marks to On (F1, Advanced tab, Diagnostics), restart the game, make it crash again and attach that log. The `vk: pass marks` lines then name what the GPU was drawing.

+        ### Save and input recording
+
+        When the crash comes back at one place in the game (an area, a shrine, a cutscene, a quest step), the save that gets there lets us crash it on our machine.
+
+        1. Zip the `profile` folder next to `totk.exe` and attach it. Say which slot you load, or that you use the autosave.
+        2. If it takes more than walking a few steps from the save: turn on Input recording (F1, Advanced tab, Diagnostics), restart the game, load the save, make it crash, and attach `input-record.txt` from the logs folder together with the `totk.log` of that run.

+        ### Recording the log
+
+        1. In the settings menu (F1), Advanced tab, Diagnostics: turn on Performance log. For freezes and hitches, also turn on Flight recorder. Restart the game: both take effect at the next start.
+        2. Play at least three minutes in the place where it happens. The log gets a frame-time summary every 60 s, and a line for every frame over 50 ms that names what the frame waited for.
+        3. With the flight recorder on, press F8 right after a hitch. It also saves on its own after every frame longer than the freeze threshold (100 ms), at most once per 10 s.
+        4. Close the game with Quit game in the menu or the window's close button. Do not end it from Task Manager: the last summary is written when the game exits.
+        5. Copy `logs\totk.log` from the folder of `totk.exe` before you start the game again.
+        6. Each flight recorder save is a folder; the log line `flight: dump` names it. Zip the folders and attach them.
+        7. Turn both off again afterwards: they cost a little frame time.

+
+        Close the game with Quit game in the menu or the window's close button, then copy `logs\totk.log` from the folder of `totk.exe` before you start the game again.
+
+        **Audio.** Open `totk.ini` in the folder of `totk.exe` and add the line `trace = audio`; when the file already has `trace = perf` (Performance log on), change it to `trace = perf,audio`. Start the game, play at least two minutes where the sound goes wrong and close the game. The log then has an `audio:` line every 5 s with the buffer underruns. Name the output device and how it is connected (speakers, headphones, USB, Bluetooth, HDMI), and attach a short video with sound if you can. Remove the line afterwards.
+
+        **Controls and input.** Name the controller and how it is connected (USB, Bluetooth, Steam Input). Does it also happen with keyboard and mouse?
+
+        **Controls, game logic, anything you can trigger again.** Turn on Input recording (F1, Advanced tab, Diagnostics), restart the game, load a save, make the bug happen and close the game. Attach `input-record.txt` from the logs folder and a zip of the save you loaded: the `profile` folder next to `totk.exe`. The recording replays what you did, so we can see the bug on our machine.
+
+        **Installer.** Attach the newest `install-*.log` from `temp\logs` in the folder of `TotK-Setup.exe` (on Linux: `.setup-temp/logs` in the install folder), and the log file the error message names.

-Early development. The game is playable on Windows; visual bugs and crashes are still expected.
+Early development. The game is playable on Windows and Linux; visual bugs and crashes are still expected.

 Report problems as issues, following [CONTRIBUTING.md](CONTRIBUTING.md).

 ## Features

 - Native code, not emulation
- Game updates 1.2.1 and 1.4.3, with saves that carry over between them
- 60 fps by default; up to 360 fps or the monitor's refresh rate (experimental)
+- Game updates 1.1.0, 1.2.1 and 1.4.3; 1.2.1 and 1.4.3 saves carry over between them
+- Takes NSP and XCI game files, and compressed NSZ and XCZ as they are: the setup unpacks them itself
+- 60 fps by default; up to 144 fps or the monitor's refresh rate (experimental)
 - Custom resolutions (1080p, 2k...), supersampling and AMD FSR 1 upscaling
+- NVIDIA DLSS / DLAA on RTX GPUs: the setup downloads `nvngx_dlss.dll` from NVIDIA's DLSS SDK repository
+  (github.com/NVIDIA/DLSS, NVIDIA RTX SDK license) when it finds an RTX GPU; untick it in the setup to skip it
+- HDR10 output with peak, game and HUD brightness settings
+- 16:10 (Steam Deck, handhelds), 3:2 (Surface, Framework), 21:9 and 32:9 (ultrawide) game resolutions, with the camera and the interface in that shape
+- Anisotropic texture filtering up to 16x, for sharp ground into the distance
 - In-game settings menu (F1) and performance overlay (F10)
+- Play time across runs on the Game tab of the settings menu, kept in `playtime.txt` next to the saves
+- Discord Rich Presence ("Playing TotK Recomp" with the play time), off by default, own application id supported
+- Setup and in-game menu in English, Russian, Brazilian Portuguese and Simplified Chinese
 - Keyboard, mouse and gamepad with remapping, rumble and gyro
+- Stereo or 5.1 surround sound output
+- Xbox button prompts: LB, RB, LT, RT, Menu and View, and A, B, X and Y as labelled on the button to press, with either button layout
 - Shaders prepared at install instead of during play
+- Mods made for emulators: unpack a mod into the `mods` folder next to `totk.exe`; switch and order them in the menu. RomFS
+  mods, TKMM's merged output and ExeFS code patches (`.ips`, `.pchtxt`) work; the game rebuilds itself for code patches
+  ([docs/mods.md](docs/mods.md)). HD texture packs work: the port grows the texture heap a pack asks for by itself. Tested
+  with the HDPacks.com 4K Texture Pack v1.0 on 1.4.3 and 1.2.1; other packs come with no guarantee
+- Atmosphère cheats: put a cheat file into a mod and switch its cheats in the menu ([docs/cheats.md](docs/cheats.md))

 ## Planned

- Linux and the Steam Deck
- Mods made for emulators: unpack a mod into a `mods` folder
- Custom aspect ratios, including ultrawide
 - VRR

 ## Installing

-Requirements: Windows 10 or later, an x86-64 CPU with AVX2, a GPU with Vulkan 1.3 and `VK_EXT_external_memory_host`, about 36 GiB free during setup (20 GiB after).
+### Windows
+
+Requirements: Windows 10 or later, an x86-64 CPU with SSE4.2 (AVX2/FMA machines get a faster build), a GPU with Vulkan 1.3 and `VK_EXT_external_memory_host`, about 36 GiB free during setup (20 GiB after).

 1. Download `TotK-Setup-<version>-windows.zip` from [Releases](../../releases/latest) and unpack it.
 2. Start `TotK-Setup.exe`. If SmartScreen warns about an unsigned app, choose *More info*, then *Run anyway*.
-3. Pick your game files, the language and an install folder, and press *Start*. The setup builds the game once.
+3. Pick your game files, the language and an install folder, and press *Start*. The setup builds the game once. With
+   an NVIDIA RTX GPU it also downloads NVIDIA DLSS, unless you untick *Download NVIDIA DLSS*; turn DLSS on in the
+   menu (F1).
 4. Play `totk.exe` from the install folder.

-To update, run a newer `TotK-Setup.exe` on the same folder; saves and settings are kept. Settings are in the in-game menu and in `totk.ini` ([totk.ini.example](totk.ini.example) lists every key). Controls: [docs/controls.md](docs/controls.md).

+Requirements: as on Windows, plus Linux 6.7 or later and glibc 2.34 or later (Ubuntu 22.04, Debian 12, Fedora 35, SteamOS 3).
+
+1. Download `TotK-Setup-x86_64.AppImage` from [Releases](../../releases/latest), or build it ([docs/installer.md](docs/installer.md), "Linux release").
+2. Make it executable (`chmod +x TotK-Setup-x86_64.AppImage`) and start it. On a Steam Deck, do this in Desktop Mode.
+3. Pick your game files, the language and an install folder, and press *Start*.
+4. Play `totk` from the install folder.

 ### 4. Graphics

 - NVN front end from MacNativeGames (`nvn_api_*.c`, `nvn_obj.h`, texture layout and deswizzle). The game records command buffers through it; nothing reaches the GPU until the game submits.
 - Vulkan 1.3 back end in place of MacNativeGames' Metal one. At `QueueSubmitCommands` the recorded NVN commands are replayed into Vulkan command buffers (`vk_exec*.c`).
 - Memory pools. Apple's unified memory let MacNativeGames use the game's pools zero-copy. The back end imports the pools as host memory (`VK_EXT_external_memory_host`). On a discrete GPU, pools bound as buffers are mirrored in device-local memory and the pages the CPU wrote (write watch, above) are uploaded before a replay; idle pool regions are made read-only so the write-watch queries skip them (`vk_memory.c`). GPU-rendered textures are written back when the CPU reads them: on a pool invalidate, on a CPU copy, and for small targets once the CPU waits for a fence (`vk_texture.c`).
- Replay thread. `TOTK_REPLAY_ASYNC=1` moves the replay off the submitting thread onto a queue at most one frame behind the game; reads of GPU results wait for the newest writer instead of draining the queue (`vk_backend.c`). It is off by default because no timing has shown a gain yet.
- Recorder thread. The Vulkan calls the replay makes into its command buffer are made by a thread of their own (`vk_rec.c`, after Savage Wind Recomp and LAS Recomp): each `vkCmd*` copies its arguments into a packet of a ring and the recorder makes the calls in order; calls into other command buffers are made at once, and the submit waits until the ring is empty. In the town on an RX 9070 the replay takes 17% less time on the submitting thread. `TOTK_VK_RECORDER=0` makes every call on the submitting thread.
+- Replay thread. `TOTK_REPLAY_ASYNC=1` moves the replay off the submitting thread onto a queue at most one frame behind the game; reads of GPU results wait for the newest writer instead of draining the queue (`vk_backend.c`). It is off by default. Where the game waits for the GPU it overlaps the replay with the game threads (a GTX 1650 in the Depths, issue #88), a gain measured only there; while it was the default, a GTX 1660 Ti at the 60 fps cap with the GPU at 26 % reported uneven motion (#659). It adds up to a frame of latency; `replay_async = 1` turns it on.
+- Recorder thread. The Vulkan calls the replay makes into its command buffer are made by a thread of their own (`vk_rec.c`, after Savage Wind Recomp and LAS Recomp): each `vkCmd*` copies its arguments into a packet of a ring and the recorder makes the calls in order; calls into other command buffers are made at once; the recorder also ends the command buffer, and the submit waits until it has. In the town on an RX 9070 the replay takes 17% less time on the submitting thread. It is off by default on AMD GPUs, where the driver loses the device or hangs the GPU at startup with it (`TOTK_VK_RECORDER=1` forces it on, `=0` makes every call on the submitting thread).
 - Uniform snapshot. The game rewrites per-object uniform blocks on other threads soon after it submits the frame
  that reads them, while the replay still records it. At the start of a submission's replay every uniform range it
  binds from CPU-written pools is copied, and the draws bind the copy (`vk_usnap.c`, after MacNativeGames'
  `TOTK_UBO_SNAPSHOT`); without it, late draws read another object's matrix.
+- Uniform updates. `nvnCommandBufferUpdateUniformBuffer` between the draws of a pass is replayed as an overlay: the
+  bytes go to scratch memory, later bindings of the range bind them, and the copies into the game's buffers are
+  recorded behind one barrier when the pass ends (`vk_exec_draw.c` `op_update_ub`, `TOTK_UB_OVERLAY`). A copy at the
+  update itself would end the pass with a full barrier, which the terrain paid before most of its draws.
 - Driver data. The NVN driver keeps a per-stage constant bank (c0) that shaders read for things like point size, dispatch size and base instance. The back end fills it the way the driver does.
 - Shaders: the Ryujinx translator 1.3.2 with MacNativeGames' patches and ours (`tools/xlate/patches/`), built with .NET 10 NativeAOT as `totk_xlate.exe` and run as a separate process. Its SPIR-V goes to Vulkan directly. `tools/prepare_shaders.py` and `totk.exe --prepare-shaders` translate and compile the variants of MacNativeGames' shared list ahead of play (29,587 for 1.4.3); the rest are translated on first use and cached on disk.
 - Pipelines: `VK_EXT_graphics_pipeline_library` where the driver has it. Shader stages are compiled ahead into libraries; a draw that meets a new state links them at once (fast link), and an optimised pipeline replaces the linked one when a background thread finishes it. Pipeline keys seen in play are saved and built at boot. A draw whose pipeline is not ready is skipped when one of its pass's targets was rendered in the previous frame, and waits otherwise, so one-shot passes are never lost; a full-screen draw is skipped as well rather than waiting (`TOTK_PIPE_SKIP`); the stage libraries a waiting draw needs are built on idle workers in parallel (`TOTK_PIPE_WAIT`). Without the extension, a missing pipeline is built on a worker and the draw waits or is skipped by the same rule.
 - Resolution. Patch sets make the game read its output, swapchain and scene sizes from the patch page
  (MacNativeGames' sites); `resolution.c` sets them from `output_res` and `render_scale` and grows the texture heap
  and the application pool to match. When the window is larger than the output, `vk_fsr.c` runs AMD FSR 1 (EASU,
-  RCAS) on the present.
+  RCAS) on the present. An `output_res` that is not 16:9 (more than 1% off, `res_is_16x9`) also switches on the
+  `aspect` patch set, which hands the output's ratio to the camera, and `romfs.c` `overlay_init` loads the
+  `romfs-patches-<w>x<h>` overlay for it when it exists (`tools/make_romfs_patches.py --aspect`, laid out by
+  `tools/ultrawide_layout.py`; the installer builds fifteen sizes: 21:9 2560x1080, 3440x1440, 3840x1600, 5120x2160,
+  32:9 3840x1080, 5120x1440, 16:10 1280x800, 1680x1050, 1920x1200, 2560x1600 and 3:2 1920x1280, 2160x1440, 2256x1504,
+  2880x1920, 3000x2000). A wider layout moves the HUD to the
+  screen's corners, a narrower one to its top and bottom edges. Other sizes get the camera of their shape and the 16:9
+  HUD stretched over it. The `aspect` setting (`fit`, the default; `stretch`) decides what the present does
+  when the window's shape differs from the output's: `fit` letterboxes, where a 16:9 game in a wider window used to be
+  stretched.
+- HDR (`hdr = 1`, `vk_hdr.c`). The game tonemaps its scene into an r11g11b10f target, upscales it and draws the HUD
+  into another float target, and a last draw copies that into the 8-bit sRGB window texture it presents. With HDR on,
+  the tonemap's fragment shader (recognised by its constants and resource names, not a hash) runs as
+  `shaders/hdr_tonemap.frag`, which keeps highlights up to the display's peak; the present reads the float target the
+  window texture was copied from (any other last draw into it, such as a menu or a movie, leaves the window texture,
+  shown at the HUD's white); a compute pass turns the picture into PQ code values in Rec. 2020 for an HDR10
+  swapchain, which FSR 1 or the blit then scale; the in-game menu is drawn into an RGBA8 image and blended on at the
+  HUD's white. Without an HDR10 surface format (Windows with "Use HDR" off, a compositor without colour management)
+  the swapchain stays SDR. `TOTK_SHOTS` reads the window texture, so its pictures clip highlights in HDR.
+- DLAA (`vk_dlaa.c`, `dlaa`, off by default). NVIDIA DLSS at the scene's own size, through the driver's NGX core loaded
+  at run time (no SDK code compiled in). It runs on the R11G11B10F light target right before the bloom chain's first
+  pass, so post effects and the HUD read the anti-aliased picture. The scene's draws get a sub-pixel Halton viewport
+  jitter; camera motion vectors are reprojected from the scene depth through this and last frame's view-projection of
+  the scene camera block (constant bank c4), in double precision on the CPU. Per-object motion (`dlaa_objmv`,
+  `vk_mvprev.c`, the per-object section of `vk_exec_draw.c`, translator patch 0015): solid scene draws whose position
+  reads an object's own uniform blocks (bones c5, place c7, c6) are drawn a second time with a vertex shader variant
+  that computes last frame's position from last frame's blocks (the game writes them into two copies that take turns;
+  the uniform snapshot keeps both) and writes the difference into the motion image. `TOTK_MV_CHECK` measures the
+  vectors against the picture, `TOTK_DLAA_TIMES` times the passes on the GPU. `fxaa` switches the game's own FXAA pass.
 - Occlusion queries never block the CPU; a result that is not ready counts as visible.
 - ASTC textures are uploaded as they are where the device reports `textureCompressionASTC_LDR`, and decoded by a compute shader everywhere else (`vk_astc.c`, `TOTK_ASTC`). The CPU decoder (`tex_astc*.c`) is the fallback and the test oracle.
 - Draw state. A draw whose program, bound state and textures repeat reuses the previous draw's shaders and skips rebuilding its descriptor sets; descriptor sets are written through update templates (`vk_exec_draw.c`, `vk_pipeline.c`).

+Vega 7 of a Ryzen 5 4600G at about 34 fps). Long play sessions and the Steam Deck itself are not verified yet.
+
+Requirements:
+
+- Linux 6.7 or later: the write watch uses userfaultfd write protection with `PAGEMAP_SCAN`. SteamOS 3.8 qualifies.
+- A Vulkan 1.3 driver with `VK_EXT_external_memory_host` (RADV, NVIDIA).
+- Packages on Arch:
+
+  ```sh
+  pacman -S --needed clang lld ninja make sdl3 opus libvpx zstd vulkan-headers vulkan-icd-loader \
+      vulkan-validation-layers shaderc spirv-tools dotnet-sdk uv git
+  ```
+
+  Vulkan Memory Allocator is a single header (AUR `vulkan-memory-allocator`). Without it, `build_game.py` fetches the
+  version the Windows release pins (3.4.0) into `toolchain/vma/` on first use and checks its hash.
+
+The steps are the Windows ones with POSIX paths: `.venv/bin/python` in place of `.venv\Scripts\python`, and `totk` in
+place of `totk.exe`. `build_game.py` takes clang, lld and Ninja from PATH (or the ones in `<dir>/bin` with
+`--toolchain <dir>`) and links against the system libraries, with `libstdc++` static and an `$ORIGIN` rpath;
+`build_hactool.py` builds `hactool` with make. `tools/prepare_shaders.py` reads the shader list from
+`refs/MacNativeGames` at `origin/HEAD`, which must be the pinned commit with its history (the list format changed later).
+
+The probes open a window, so from an SSH session they need the desktop session's display, or they stop at `gpu 0
+skipped: no graphics+compute+present queue family`: on Wayland `XDG_RUNTIME_DIR=/run/user/$(id -u)
+WAYLAND_DISPLAY=wayland-1 SDL_VIDEODRIVER=wayland` (the socket name is in `$XDG_RUNTIME_DIR`), on X11 `DISPLAY=:0`.
+
+Memory: on Windows the GPU imports guest memory and `GetWriteWatch` tracks the CPU's writes to it. On Linux,
+re-protecting imported memory invalidates the driver's userptr buffer on every submit (about 1.3 ms per 16 MiB on
+amdgpu), and importing pins the pages, which drops their write protection. Each CPU-visible pool therefore gets a
+host-visible copy (shadow storage, `runtime/vk_memory.c`): the pages the CPU wrote go in before each submit, and the GPU's
+writes come back at its fence. In play that costs about 0.2 ms a frame and doubles the memory of those pools (about
+1.1 GB). `TOTK_SHADOW=1` turns it on under Windows too. The Steam Deck's RADV has `VK_EXT_external_memory_host` as
+well: the shadow copies are chosen for the measured cost above, not for a missing extension.
+
+The Deck's GPU (Van Gogh) has no native ASTC, so its textures go through the compute decoder (`runtime/vk_astc.c`,
+`TOTK_ASTC`) as on desktop AMD GPUs without it; frame times measured there include it.

+# Cheats
+
+The port reads Atmosphère cheat files, the format Switch homebrew and the emulators use. It ships no cheat files: a cheat file goes into a mod in the `mods` folder next to `totk.exe`, like any other mod ([mods.md](mods.md)). Open the menu (F1) and switch the cheats on the Cheats tab. The switches are saved under `[cheats]` in `totk.ini`.
+
+## Adding a cheat file
+
+1. Find the cheat file for your update. Cheat sites and collections name it after the first 8 bytes of the game's build id:
+
+   | Update | File |
+   |---|---|
+   | 1.2.1 | `9B4E43650501A4D4.txt` |
+   | 1.4.3 | `277178B7DBA1B6D4.txt` |
+
+   The Cheats tab names the file the installed game reads when no mod holds one, and `logs\totk.log` says `cheats: no enabled mod holds cheats/<id>.txt`.
+2. Put it in the `cheats` folder of a mod, a folder of its own under `mods`:
+
+   ```
+   mods\
+     My cheats\
+       cheats\
+         277178B7DBA1B6D4.txt
+   ```
+
+   A download laid out for the Switch's SD card or an emulator works as it is: unpack it into a folder of its own under `mods`, and the port finds `atmosphere\contents\0100F2C0115B6000\cheats`, `contents\0100F2C0115B6000\cheats` or `0100F2C0115B6000\cheats` inside it. The file name's case does not matter.
+3. Start the game. Cheats that write the game's memory work now.
+4. Cheats that change the game's code need the game rebuilt with them. When the game starts and finds such cheats it did not build, it opens the setup's rebuild window, which builds them in (a few minutes; the shaders stay prepared) and starts the game again. Until then they are greyed out with "after the rebuild". When the rebuild fails or you cancel it, the game starts without them and does not try again for the same cheats; "Rebuild the game now" on the Cheats tab tries again. `mods_rebuild = off` under `[mods]` in `totk.ini` turns the automatic rebuild off; running `TotK-Setup.exe` on the same folder does the same job by hand. Saves and settings are kept.
+5. Switch the cheats on the Cheats tab of the menu.
+
+The Cheats tab lists the cheats grouped by mod, in the order of the Mods tab. A mod switched off on the Mods tab, or one the port cannot use, contributes no cheats; the change applies at the next start. The Mods tab says how many cheats each mod brought.
+
+## The file format
+
+Standard Atmosphère: a `[name]` line starts a cheat, `{name}` a master cheat that is always on, and the cheat's opcodes follow as 8-digit hex words. A name with no opcodes is shown as a heading. The file's title line (the one with `TID=`) is not shown.
+
+```
+[The Legend of Zelda: Tears of the Kingdom v1.4.3 TID=0100F2C0115B6000 BID=277178B7DBA1B6D4]
+

+
+[A data cheat (Hold ZL+X)]
+80000104
+580F0000 XXXXXXXX
+640F0000 00000000 YYYYYYYY
+20000000
+```
+
+The words above are placeholders: `XXXXXXXX` an offset, `YYYYYYYY` a value.
+
+Each cheat's switch is `cheat_<hash> = 1`, where the hash is FNV-1a 32 of `<mod folder name>/<cheat name>`. A name repeated in one file gets `#2`, `#3` and so on. The build names each code cheat the same way, so renaming a mod's folder resets its cheats' switches to off and makes the next start rebuild its code cheats. Rename the folder before you switch its cheats on.
+
+## How cheats run
+
+The game's code is compiled ahead of time, so a cheat cannot write new instructions into it while the game runs. The port sorts each cheat by what it writes (`tools/cheats.py` at setup, `runtime/cheats.c` in game):
+
+| Kind | What the cheat does | How the port runs it |
+|---|---|---|
+| code | Opcode 0 writes into main's code | Built into the game at setup as a patch set (`recomp/patches.py`); switches at once. |
+| key | Code writes inside a button condition (`8` mask, writes, `21` else, the original words, `20`) | A patch set that is on while the cheat is on and the buttons are held. |
+| data | Writes data only: heap, main's data, pointer chains, button conditions | Runs in a cheat VM after dmnt's, opcodes 0 to A, every presented frame while on. |
+| master | `{name}` with code writes | A patch set that is always on. |
+| restore | Writes back only the game's original instructions | Not needed: switching a cheat off restores them. Greyed out. |
+
+A cheat whose code writes call or jump into a code cave the cheat writes itself (into main's zero padding) gets the cave inlined at the call site. The setup builds the code cheats of every mod in the `mods` folder, switched on or off, so switching a mod on later needs only a restart. A code cheat added or edited after the last build waits for the rebuild; a data cheat runs at the next start.
+
+Not supported, and shown greyed out with the reason:
+
+- the 0xC and 0xF opcode extensions;
+- opcode 5 with a register offset;
+- code writes mixed with other opcodes, except the button pattern above;
+- code writes that change the CPU flags differently from the game's instruction, or code caves with branches or pc-relative instructions.
+
+`build-cache\cheats.status` next to `totk.exe`, written by the setup, records which cheats were built and how; the log line `cheats: ...` sums them up at start. When the code cheats cannot be built, the setup warns and installs the game without them.

+
+## Xbox button prompts
+
+`TOTK_PROMPTS` (`prompts`, the *Button prompts* row on the Controls tab, read at start) picks the controller whose buttons the game's prompts show: `nintendo` (default) keeps the game's own, `xbox` shows an Xbox controller's, `pc` the keyboard and mouse (PC button prompts, below).
+
+- L, R, ZL, ZR, Plus and Minus become LB, RB, LT, RT, Menu and View, and the d-pad prompts a cross with an arrow for each direction meant. The letters on the keys are cut out in the game's own text font.
+- A, B, X and Y name the label of the button the pad layout presses, so each prompt names the button to press. `pad_layout = nintendo` plays an Xbox pad by position: the right button, labelled B, does Switch A (interact, confirm), and the bottom one, labelled A, does Switch B (run, cancel), so the prompts swap A with B and X with Y. `xbox` and `auto` put Switch A on the button labelled A, and the letters stay.
+
+| Switch | `nintendo` layout | `xbox` or `auto` layout |
+|---|---|---|
+| A, B, X, Y | B, A, Y, X | A, B, X, Y |
+| L, R | LB, RB | LB, RB |
+| ZL, ZR | LT, RT | LT, RT |
+| Plus, Minus | Menu, View | Menu, View |
+| D-pad | cross | cross |
+
+The action prompt (`DoCommand_00`) shows its button in a diamond whose shape gives the face buttons' positions as on a Switch, with the other three letters around it. With `nintendo` its letters are swapped with the rest and every one names the button in that place. With `xbox` and `auto` the letters stay and the diamond is laid out as an Xbox pad: A at the bottom, B on the right, X on the left and Y at the top, the button the prompt names lit in its place, its bar reaching left from X and right from the others (`tools/make_romfs_patches.py`, `bflyt_xbox_diamond`: the panes of `blyt/DoCommand_00.bflyt` take their partner's place, A's of B and X's of Y). The sticks keep the Switch icons, and so do prompts drawn as fixed images (some tutorial animations).
+
+The prompts are part of the game's fonts, textures and messages, so they follow the layout and not the bindings. A button remapped with a `bind_` line or on the Controls tab keeps the prompt the game draws for it, which then names the wrong button. Use the Xbox prompts with the default bindings.
+
+The game reads its UI archive and fonts once at boot, so the prompts change at the next start, also after `pad_layout` changes between `nintendo` and the others (the menu says *prompts change after restart*); the buttons change at once. Under that note the menu offers *Restart now*: after a confirmation it writes `totk.ini`, closes the game as *Quit game* does and starts the game again with the same command line, which waits until the old process is gone before it opens the log and the saves (`runtime/gfx_present.c`, `gfx_window_closed`; `plat_restart` and `plat_restart_wait` in `runtime/platform/win32.c` and `linux.c`). Progress since the last save is lost, as with *Quit game*; while the game writes a save, the confirmation waits. With `prompts = xbox` the game loads `romfs-patches-xbox` (`pad_layout = nintendo`) or `romfs-patches-xbox-label` (`xbox`, `auto`) next to `romfs-index.bin` in place of `romfs-patches` (`runtime/romfs.c`, `overlay_init`; `runtime/input_map.c`, `input_prompts_folder`): the same 60 fps patches, with the prompts drawn from the game's own files by `tools/make_romfs_patches.py --prompts xbox` or `--prompts xbox-label` (`tools/button_icons.py`, after MacNativeGames' `make_button_icons.py`), which the setup runs next to the plain one:
+
+- every prompt but the button guide in play is text in the button font, `scft/External.bfotf` in each `Font/Font*.Nin_NX_NVN.bfarc.zs`: glyphs U+E040 to U+E043 (A B X Y), U+E044 to U+E047 (L R ZL ZR), U+E04B and U+E04C (Plus, Minus), U+E049 and U+E060 to U+E065 (the d-pad). fontTools writes the font again, so the archives grow and the folder also carries the resource size table (`System/Resource/ResourceSizeTable.Product.<n>...rsizetable.zs`) with their entries raised by as much; without that the game stops at start.
+- the button guide in play draws L and ZL from the images `Nt_KeyTexL_00` and `Nt_KeyTexZL_00` of the Common archive's `timg/__Combined.bntx`, painted with the same icons. The action prompt draws its button from `Nt_KeyTexA/B/X/Y_00`, whose image data is swapped for `nintendo`, and the diamond's letters are text the game takes from `LayoutMsg/DoCommand_00.msbt` of each language's `Mals` archive (and the layout's own text panes behind it), swapped the same way.
+
+The Switch prompts stay, with a note under *Button prompts* and a `RomFS overlay: ...` line in the log, when the folder is missing (an install made by an older setup, or one where the setup could not prepare it and showed a warning; running the setup again on the install folder writes it), when it fails its check, with a game resolution of another shape than 16:9 (its own UI layout wins; 16:10 and 21:9), and when the `romfs_mods` folder replaces one of its files: `romfs-patches` then loads in its place, where two overlays replacing one file would stop the game. In a source build, `.venv-py314\Scripts\python tools\make_romfs_patches.py --version <ver> --prompts xbox` (and `--prompts xbox-label`) writes `build\<ver>\romfs-patches-xbox` (`-label`); it needs fontTools from `tools/requirements-py314.txt`. `--xbox-prompts` is the older name of `--prompts xbox`.
+
+## PC button prompts
+
+`prompts = pc` (*PC* on the *Button prompts* row) shows the key or mouse button the default keyboard bindings press each Switch button with, whatever the pad layout. The game loads `romfs-patches-pc` in place of `romfs-patches`, written by `tools/make_romfs_patches.py --prompts pc` (`button_icons.py`, `pc_icons`), which the setup runs next to the Xbox ones:
+
+| Switch | Prompt |
+|---|---|
+| A, B, X, Y | E, Shift, Space, left click |
+| L, R, ZL, ZR | Q, R, right click, F |
+| Plus, Minus | Tab, M |
+| D-pad | 1 (left), 2 (up), 3 (right), 4 (down), as a cross or the keys of the directions meant |
+| Left stick, its press | W A S D (or the keys of the directions meant), Ctrl |
+| Right stick, its press | the mouse, with an arrow for each direction meant, C |
+
+- The glyphs keep the width of the game's own, so the right-aligned guides do not run into their text. A key is a rounded square with its label cut out in the game's own text fonts; a mouse button is a mouse with that button filled and the others hollow.
+- The button guide in play draws every button from images of the Common archive (`Nt_KeyTexA/B/X/Y/L/ZL_00`, `Nt_KeyTexLSt_00` and `_01`, the stick tilted and pressed): all of them are painted with the same icons. The letters of the action prompt's diamond are one character of the Normal font each: E, an arrow for Shift, a bar for Space, L and R for the mouse buttons.
+- Like the Xbox prompts they follow the defaults and not the bindings. `--binds <totk.ini>` draws the first key of each `bind_` line of that file instead, for a folder made by hand.
+- At a game resolution of another shape than 16:9 the game loads `romfs-patches-pc-<w>x<h>` in place of `romfs-patches-<w>x<h>` when it is there: the same prompts with that shape's UI layout, `make_romfs_patches.py --prompts pc --aspect <w>x<h> --out <install>\romfs-patches-pc-<w>x<h>`. The setup does not write those, so without one the Switch prompts stay (*off at a game resolution not 16:9*).

 ## Window keys

 | Key | Gamepad | Action |
 |---|---|---|
 | F1 or Esc | Minus and Plus together | open or close the settings menu; the game gets no input while it is open |
-| F10 | | performance overlay: off, frame rate, full panel |
+| F10 | L3 + R3 (both stick clicks) | performance overlay: off, frame rate, full panel |
 | F11 | | borderless fullscreen on or off, saved to `totk.ini` |

 The Minus+Plus combo never reaches the game. In the menu the arrow keys, the D-pad or the left stick move, Enter or A selects, Q and E or L and R switch tabs, Esc or B goes back (Switch button names, as in the table above).

 ## Remapping

-The *Controls* tab of the settings menu lists, under the button layout, every Switch button and the eight stick directions the keys drive (movement and camera), each with two key cells and a controller cell. Select a cell, press A or Enter, then press the new key, mouse button or controller button; Esc or five seconds without a press cancel, and a controller button cancels a key cell. Delete, Backspace or X clears the selected cell. A key another action has moves to the new one (the description names the action it left); a controller button swaps with the one it replaces. A remapped controller button is physical: from then on the face buttons (A B X Y) stay where they are in both layouts, until the buttons are put back as the layout in use has them or *Reset all buttons* is chosen. F1, F8, F10, F11 and Esc cannot be bound (the menu, the flight recorder and the window keep them). Punctuation keys are named by their place on a US keyboard; the menu shows the character the keyboard layout in use puts there.

 ## Mouse camera

-Mouse motion (raw input) becomes right-stick deflection. Each presented frame takes the counts moved since the last frame, divides by the frame time and sets the deflection to `counts per second * TOTK_MOUSE_SENS / 3000` of full, held for that frame, so the turn rate does not depend on the frame rate. This is not mouselook: the game's stick curve and dead zone still apply, so very slow movements do nothing and a fast flick saturates. The mouse deflection competes with the gamepad and arrow keys by the larger-deflection rule.
+`mouse_mode = direct` (the default) turns the camera by the raw mouse motion on games 1.4.3 and 1.2.1, through hooks in the game's camera code (`runtime/mouse_direct.c`, the `mouse_direct` sites of `recomp/patches-v143.txt` and `recomp/patches-v121.txt`). None of them changes a step of the gamepad alone. The free-orbit camera receives raw-count
+angular increments at its final spherical-angle output: 0.08 degrees per count on both axes at sensitivity 1 (about
+14.3 cm a turn at 800 DPI), with no time multiplier, curve or carry into later frames. The controller's persistent pitch/yaw move with
+the output. Mouse input is removed from its stick path first, so the camera's later vertical signed-square curve and
+velocity filters cannot process it a second time.
+The aiming camera (bow, throwing), the Purah Pad camera, the scope, the ability camera (Ultrahand, Fuse, Ascend,
+Recall, Autobuild), the horse camera, lock-on, the bow drawn while locked on, climbing (walls and objects), the
+waterfall's turn, shield surfing, the wakeboard and the dialogue cameras take the mouse the same way, at the same
+degrees per count: each turns by
+the stick times its own speeds and the frame time and adds that to a base angle, so the load of the stick it turns by
+gets the gamepad's part only and the load of that base angle gets the mouse's degrees (`camera_load`, two sites per
+axis per camera). Their speeds, time step, slow motion (bullet time) and, for the Purah Pad camera and the abilities,
+the eased curve their pitch moves along do not touch the mouse; their own limits, collision and blends apply to the
+result. Past the pitch limit of the scope or the ability camera the stick moves the camera's distance; the mouse's
+motion past the limit keeps doing that through the stick. Recall's cursor is the ability camera's offset mode: the
+camera keeps a direction, the stick moves the cursor across the screen (ReverseRecorderCursorSpeed, within
+ReverseRecorderCursorRange) and the camera follows it by up to ReverseRecorderCameraRange (10 degrees across, 7.8 up).
+The mouse moves the cursor so that its aim, the camera's follow plus the cursor's angle from the screen's centre (the
+offset taken as the screen's half width or height at the camera's 50 degree view and aspect ratio), turns as many
+degrees a count as the camera does elsewhere. The follow range is read from the game each step (until it has been read
+once, the mouse is stick input there). The stick loads that only test for input keep the mouse in the stick. A step with mouse motion that no
+direct hook took is logged (`mouse: step N with mouse motion took the stick path`, the first 30, then one in 600, with
+the player's state), so the cameras still on stick input show in `logs/totk.log`.
+Lock-on keeps pointing the camera at the target; the stick, and so the mouse, adds an offset around that direction,
+which the game limits and lets return: the mouse's degrees are the step's turn the game adds to the offset and judges
+the return by.
+Shield surfing and the wakeboard turn their pitch by the square of the stick's y and move a second camera parameter
+with it: their stick y keeps the mouse (that parameter and the camera's state follow it as before), the pitch gets
+the degrees, and the pitch turn the game made from y is cut to the gamepad's share (p |p| / t |t|). Their stick x, and
+the dialogue camera's (which is also its test for input), give a tiny value in the mouse's direction when the
+gamepad's axis is at rest, so the camera still sees input without a stick turn.
+Two inputs stay stick input: the waterfall's vertical axis moves the camera's height, not an angle, and the horse's
+lock-on without a target (HorseLockOnEmpty) turns the stick's position into an offset that returns when the stick
+does, which a mouse has no position for.
+Those receive input after
+the radial dead zone, unit-circle clamp and stick response exponent: x is 0.0343 stick units a count over the frame
+ratio (the stick turns yaw 70 x / 30 degrees a step) and y 70 / 51 times that, linear like their pitch (51 y / 30
+degrees a step), so both axes turn by the same amount for the same motion. `stick_sens` (which scales the game's
+stick turn rates) is divided out. While the player uses an ability and the ability camera's hooks do not take the
+mouse, its part is scaled by 1 / 0.8 and 70 / (1.5 x 51), the ability camera's own stick scales.
+The player's verbs are read every 50 ms from the player actor (the player root's GOT slot main+0x3969918, the
+component array +0x228, its AS component +0x158 and the verbs of its five slots). Ultrahand has a separate hook after
+its manipulation input's power curves; it gets 0.01 stick units a count over the frame ratio, at most three full tilts
+a step.
+`mouse_aim_scale` (0.1 to 3, default 1) multiplies the mouse's motion while the bow is drawn (the verb UseBow or
+DrawnBow with ZR held). The game's camera inversion and gamepad response remain in effect. `mouse_sens` scales raw
+counts, with the same meaning as in 0.3.10 (the free camera turns 0.08 degrees a count at 1, and now every other camera
+does too); its scale differs from the stick-emulation mode.
+The Controls tab switches between *Direct* and *Stick emulation* (`mouse_mode = stick`).
+The orbit camera keeps its desired pitch at the final angular output, including stationary frames, so a later game
+filter cannot recenter it. The persistent filter state accounts for the camera's current vertical offset instead of
+accumulating corrections. A gamepad vertical input releases that mouse target to the game's own. The game's
+lock-on, recenter and override (aiming) drive the camera themselves: the mouse stops holding without restoring its
+earlier target, and when they end (or after the camera went 100 ms without a step) it holds the pitch the camera has
+then, so the camera does not spring back to a pitch from before the aim or to the game's default after a shot.
+While the ability wheel is open (L held and its screen, ShortCutMainItem_00 or ShortCut_00, has the focus), mouse
+counts move its virtual cursor, which stays where it was when the mouse stops. L or the D-pad held with no wheel or
+strip on screen (L soothes the horse, turns menu tabs) leaves the mouse on the camera; with the menu cursor off
+(`menu_cursor = 0`) the screens are not read and the buttons alone decide.
+The horizontal quick lists (D-pad up/left/right: materials, shields and weapons) use separate 32 ms right-stick steps,
+with at least 32 ms of neutral between them. At sensitivity 1, 32 horizontal counts request a step; a large flick
+cannot queue continued scrolling after the mouse stops. Vertical movement is ignored in these lists. Switching or
+releasing a selector resets its cursor/step state without sending the last movement to the camera. Selector input is
+not consumed by the direct camera or Ultrahand hooks.
+To detach a fused part from what Ultrahand holds, shake the mouse left and right, or press G (`bind_SHAKE`). A press
+swings the right stick left and right for 0.8 s, holding the key keeps it swinging. With `mouse_mode = direct` a shake
+of the mouse while Ultrahand holds an object swings the right stick with it: once the swings (10 degrees of camera turn
+or more each, 125 counts at sensitivity 1) change direction twice within 0.35 s, the stick goes full tilt the
+way the mouse moves, each side held at least two frames so the game reads it, and goes neutral as soon as the mouse
+rests. Only your own swings reach the stick, so nothing keeps swinging after you stop; shake until the part comes off.
+The camera hooks ignore that swing (the mouse turns the camera in degrees already). Turning a held object back and
+forth at an ordinary pace is slower and does not count. The arrow keys or the gamepad's right stick shaken by hand
+work too.
+A step of the gamepad alone, with no mouse motion and no pitch the mouse holds, reaches the camera exactly as without
+the hooks.
+The mapping below is still used when the camera-input hook is unavailable or the game disables camera input.
+Game 1.1.0 has no hooks and keeps stick emulation whatever `mouse_mode` says. On 1.2.1 `mouse_aim_scale` has no effect (the bow-in-hand state is not read there).
+
+In stick-emulation mode, mouse motion (raw input) becomes right-stick deflection. Each presented frame takes the counts moved since the last frame, divides by the frame time and sets the deflection to `counts per second * TOTK_MOUSE_SENS / 3000` of full, held for that frame, so the turn rate does not depend on the frame rate. This is not mouselook: the game's stick curve and dead zone still apply, so very slow movements do nothing and a fast flick saturates. The mouse deflection competes with the gamepad and arrow keys by the larger-deflection rule.

 `TOTK_MOUSE_SENS` (0 to 10, default 1; higher turns faster, 0 turns the mouse camera and the cursor capture off). While the window is the foreground window the cursor is hidden and confined to the client area. It is released on focus loss, minimise, while F11 changes the window, during a size or move loop and while a text entry is open. Esc releases it by hand: the cursor shows, the mouse camera and mouse buttons stop, and the window can be moved, minimised or closed. A mouse click inside the client area captures it again; that click does not reach the game. Activating the window by a click on its title bar or border does not capture, so it can be dragged or closed right away; Alt+Tab or a click in the client area captures as before. `TOTK_INPUT=none` disables the capture too.

+`TOTK_STICK_DEADZONE` (0 to 50, default 8) is the gamepad stick dead zone in percent of full deflection, the same for both sticks. It is round: a stick inside the circle reads centred, and the rest of its travel is scaled to start at 0 at the edge, so full deflection still reaches full. Raise it for a stick that drifts. The game's own dead zone applies after it. `TOTK_LSTICK_DEADZONE` and `TOTK_RSTICK_DEADZONE` (the *Left/Right stick dead zone* rows under *Analog sticks* on the Controls tab) set one stick each and fall back to `TOTK_STICK_DEADZONE` while unset, so a worn stick can get a larger zone than the other. With a gamepad connected each row shows its stick's deflection now, before the dead zone (*stick now*): let go of the stick and set the row a few percent above the value it rests at.
+
 The stick direction bits (`StickLLeft` to `StickRDown`) are derived from the sticks at 50% deflection. A gamepad plugged in later is picked up within one second; with none connected the log says `input: no gamepad`.

+## Mouse in the game's menus
+
+On game 1.4.3, while one of the game's menus has its focus box (the frame the d-pad moves: the title, the save list, the inventory and its System tab, Options, shops, dialogue choices), the cursor is released from the mouse camera and shown in the middle of the window. A focus gap of up to 300 ms (a tab switch, a popup opening: the game drops the focus box for a frame or two) keeps the pointer where it is instead of capturing and centring it again. The item under the pointer takes the focus as if the d-pad had moved there, with the game's highlight, sound and description; a left click is A on it, a right click is B. The middle and side mouse buttons keep their bindings (bound to L and R they turn the tabs), and T presses Y (sort). The keys and the pad keep working, and the focus moves only when the pointer moves. This happens only while the keyboard and mouse are the device used last: after a gamepad button press or a stick pushed past half way the menus are as on the console, with no pointer, until the mouse moves or a key is pressed (`input_kbm_last` in `runtime/input.c`). The ability wheel, the d-pad strips, Autobuild and the Purah Pad's camera stay gameplay: the mouse keeps the camera there. The map has no focus box; it is found in `eui::ScreenMgr`'s list of open screens (every 100 ms: the Purah Pad's frame `AppMenuOverlay_00` with `AppMap_00` and the menu background `AppMenuBG_00`), and there the mouse moves the map's cursor as the left stick does, with the cursor still captured, and the scroll wheel zooms: each notch is a full-tilt push of the right stick (the map's zoom) for 100 ms with 50 ms of neutral after it, up (in) for a turn away from you; a fast scroll's notches wait their turn (at most four), a turn the other way drops them. The Scope opens the same map screen without the menu background and keeps the mouse camera. When the menu closes the cursor is captured again.
+
+`runtime/menu_cursor.c` reads eui's screens at each pad read and moves the focus with the writes `eui::BoxCursorMgr::moveBoxCursor` makes, so no game code is called. `menu_cursor = 0` (`TOTK_MENU_CURSOR=0`, live; the *Mouse in the game's menus* row of the Controls tab) turns it off; `TOTK_MENU_CURSOR_LOG=1` logs every screen it reads (by default the first six), with the layout size, the node count and the hit panes it uses.
+
+## Nintendo Switch 2 controllers
+
+Windows does not present the Switch 2 Pro Controller as a gamepad SDL can open (the log says `input: no gamepad`), so it needs a bridge program that wakes it and creates a virtual gamepad. The DS4Windows fork by hbashton ([github.com/hbashton/DS4Windows](https://github.com/hbashton/DS4Windows), tested with release VIIPERRC4.5.1, a pre-release) with the output set to an emulated DualSense gives buttons, rumble, gyro and accelerometer, and reads the sticks through the controller's calibration (they rest at 0 to 2%). The game reads its virtual DualSense directly; the log then shows `input: gamepad "DualSense Wireless Controller" (rumble, gyro and accelerometer, ...)` and `input: motion sensors on`. Its release notes also list Joy-Con 2 support, which is untested here.
+
+Bridges that output a ViGEm DualShock 4 (ProCon2Windows, connectyourpro as tested) give buttons and rumble but no motion: their virtual DualShock 4 reports a gyro and an accelerometer that never change, so motion aiming and Ultrahand rotation do nothing. Run one bridge at a time; Steam Input can also claim the controller, so close Steam if the bridge does not find it.

 `<frame>` counts 60 Hz ticks of game time since the first frame (presented frames at 60 fps), so the title menus get the presses at the same game time at any frame limit. `@<ms>` counts milliseconds of the world clock: game time stepped since the end of the first save load (the player leaves the title screen's origin), so a timed event lands at the same game time at any frame rate and load length. A later load, such as fast travel, still shifts what follows. In a script with timed lines the untimed ones stop when the world clock starts, as the load ends at another tick in each run. Each event logs once (`input: script frame N tick T: A`). `tools/input/load_save.txt` loads the first save from the title screen.

 `TOTK_INPUT_RECORD=<file>` (`input_record` in `totk.ini`, or Input recording in the menu) writes the merged input in the same format, one line per button press and per stick segment: events before the world clock starts by tick, the rest timed; a button or stick held when the world clock starts is cut there and goes on as a timed event. The file replays as a script, which makes it the repro to attach to a bug report.

+In direct mouse mode the recording also writes one `MOUSE` event per consumed raw displacement. These are one-shot
+displacements rather than held stick segments. They replay without cursor capture, including with `input = none`;
+the game must be accepting camera input when the event reaches its camera update.

+2. **Fonts** with Chinese, Korean or Traditional Chinese text and a firmware folder: extract the Switch system fonts
+   from the firmware into `shared-fonts/` (MacNativeGames' `extract_shared_fonts.py`, which verifies every NCA layer
+   and BFTTF header). Without a firmware folder the setup warns and goes on; the game then lacks those glyphs.
+3. **Extract** ExeFS and RomFS into the install folder and verify the hashes.
+4. **Lift** the ExeFS to C (`recomp/gen.py`, `recomp/patches-v121.txt` or `patches-v143.txt`) into a temp folder next
+   to the installer. The code cheats of the mods' cheat files and the mods' ExeFS patch files become patch sets first

+   patches and the shaders (`tools/make_romfs_patches.py`, `tools/prepare_shaders.py`,
+   `totk.exe --prepare-shaders`) in the install folder, then fold the shader cache's loose files (four per shader, about
+   117,000) into `shader-cache/shader-cache.pack` (`tools/pack_shader_cache.py`). totk.exe reads the pack first and
+   writes the translations it makes in play as loose files; running the tool again with the game closed folds those in.
+   The patches are written four times: `romfs-patches`, `romfs-patches-xbox` and `romfs-patches-xbox-label`
+   (`--prompts`: Xbox button prompts for `prompts = xbox`, the first for `pad_layout = nintendo`, the second for `xbox`
+   and `auto`), and `romfs-patches-pc` (keyboard and mouse prompts for `prompts = pc`). The three prompt folders are
+   optional: when one cannot be made, the setup warns and finishes.
+   When the graphics driver crashes while building the shaders, `prepare_shaders.py` runs that part again without the
+   variants it was building ([building.md](building.md), step 6), and the setup finishes with a warning that names how
+   many were left out.
+7. **DLSS** (the window's tick box, on by default, or `--dlss`; Windows with an NVIDIA RTX GPU): download
+   `nvngx_dlss.dll` from NVIDIA's own DLSS SDK repository (github.com/NVIDIA/DLSS, a pinned tag, NVIDIA RTX SDK
+   license) into the install folder and check its size and SHA-256 (`steps.py`, `Dlss`). The release does not ship
+   the library; NGX loads it from the folder of totk.exe for `dlaa` and the DLSS modes. A DLSS library already in the
+   folder (a newer one the player put there) is kept. Without an RTX GPU the step only logs and does nothing; a failed
+   download warns, the game runs without DLSS, and the next run of the setup tries again.
+8. **Clean up** the temp folder, except the generated C and the objects (about 1.3 GB), and write
+   `build-cache/rebuild.txt` in the install folder.

 A cancelled or failed setup resumes from the last finished step (`totk-install.json`).

+## Rebuilding for the mods
+
+The generated C and the objects stay in the temp folder, so the next lift rewrites only the chunks whose C changed and
+Ninja recompiles only those: a new or edited code cheat costs the lift (under a minute on 24 cores, a few minutes on 4)
+and a few dozen chunks, not a full compile, and the shaders stay prepared.
+
+`build-cache/rebuild.txt` holds the command that opens the setup window in its rebuild mode on the install folder
+(`installer/gui.py --rebuild <install folder>`, started through `python -c` so the release folder is on `sys.path`
+whatever the working folder), one argument per line. When an enabled mod has code cheats or ExeFS patch files the build
+lacks, `totk.exe` runs it at start and exits (`runtime/cheats.c` `rebuild_if_needed`); the
+window runs the setup on the folder at once and starts the game again when it succeeds. A failed or cancelled rebuild
+offers to start the game with the code it has; `build-cache/rebuild.skip` then keeps the same files from starting it
+again, until "Rebuild the game now" on the Cheats or Mods tab. `[mods] mods_rebuild = off` turns it off. The rebuild
+needs the release folder the setup ran from: a moved or deleted release folder means running a setup again.

 ```

 - SDL3 comes from the upstream release, not MSYS2: MSYS2's DLL imports the LGPL libiconv.
 - Every bundled third-party piece gets a row in `THIRD_PARTY_NOTICES.md`.
- The release contains nothing game-derived; `make_release.py` runs `tools/check_content.py` over the folder before it
-  finishes.
+- The release contains no code, data, text or assets of the game; `make_release.py` runs `tools/check_content.py` over
+  the folder before it finishes. The execution profiles name lifted functions by address (`f_<address>`) and hold
+  branch counts and control-flow hashes of the generated C.
+
+## Switch system fonts
+
+Simplified Chinese, Traditional Chinese and Korean text needs the Switch system fonts (`0-standard.bfttf` and the other
+nn::pl shared fonts). The game does not ship them. Without them it exits before its first frame in those languages
+(`rt_fatal` in `runtime/ov_system.c`). Supply them from your own console, in either way:
+
+- Give the setup the firmware folder (`--firmware DIR`, or the window's firmware field); the Fonts step extracts them to
+  `shared-fonts/` in the install folder.
+- Run `python tools/extract_fonts.py --firmware <dir>` with `.venv-py314` and the keys from `config.local.toml`, or
+  point `TOTK_SHARED_FONTS` at a folder that holds the extracted fonts.
+
+## Linux release
+
+`tools/make_release_linux.py` builds the same setup for Linux and packs it as `TotK-Setup-x86_64.AppImage` (the static
+type-2 runtime: no libfuse2 needed on the host). The player makes it executable and starts it; on a Steam Deck, from
+Desktop Mode. The command-line setup needs the desktop session's display (`DISPLAY` or `WAYLAND_DISPLAY`) because preparing the
+shaders opens a window; the check step fails at once without it. Building the release also needs `make` and `pkg-config`. The bundled Tcl/Tk 9.0.4 is rebuilt with
+Xft against the sniper sysroot so Russian text uses system TrueType fonts. The setup builds the game into the folder they pick, as on Windows, and the game is `totk` there with
+`libSDL3.so.0` beside it. The folder inside the AppImage:
+
+```
+AppRun                starts python/bin/python3 -m installer.gui (no bytecode written into the read-only mount)
+totk-setup.desktop, totk-setup.png
+installer/, recomp/, tools/, data/, licenses/, THIRD_PARTY_NOTICES.md, totk.ini.example, VERSION   as on Windows

+                      tools/ and recomp/ on sys.path
+llvm/                 LLVM 23 (clang, lld, llvm-ar) and llvm/sysroot: the files of the Steam Runtime 3 "sniper" SDK the
+                      game's compile and link read (about 130 files)
+runtime/              libtotkrt.a, libtotkrt-v2.a, headers, the install-side sources, totk.png; deps/ with the Vulkan
+                      headers, VMA and a static zstd
+bin/                  totk_xlate, hactool, ninja, libSDL3.so.0
+```
+
+- What we compile is built against the sniper sysroot (glibc 2.31): the game, hostcheck, hactool and the translator
+  need no newer glibc. The game links Opus, libvpx, zstd and libstdc++ statically and needs only glibc, the system's
+  Vulkan loader and the SDL3 beside it. The setup itself needs glibc 2.34 (Ubuntu 22.04, Debian 12, Fedora 35,
+  SteamOS 3): the official LLVM binaries and the `cryptography` wheel are built against it. `make_release_linux.py`
+  checks every ELF file in the folder against that floor (`check_glibc`), and the setup's check step stops with one
+  message on an older system.
+- The setup's temp folder is `.setup-temp` inside the install folder (`--temp` changes it): the AppImage is mounted
+  read-only, and a Steam Deck's `/home` is often too full for the generated C while the game goes to the SD card.
+- The game keeps Mesa's shader cache in `mesa-cache` beside `totk` unless `MESA_SHADER_CACHE_DIR` is set, for the
+  same reason: RADV fills its default folder in `~/.cache` up to 1 GB.
+- The window follows `LANG` for English or Russian, cancels through SIGTERM to the CLI's process group (the CLI handles
+  it as Ctrl+Break on Windows) and opens the finished folder with `xdg-open`.
+- Requirements beyond Windows': Linux 6.7 or later (the write watch, `docs/building.md`) and glibc 2.34.
+- Building the release needs one game version extracted and lifted (`tools/extract.py`, `recomp/gen.py`, either
+  version): the runtime library includes the generated `layout.h`, whose shared part (`MOD_COUNT`, `MOD_MAIN_BASE`)
+  is the same for both. `tools/make_release.py` takes `generated/v121`, else `generated/v143`.

 ## Constraints

- The installer steps contain no Win32 calls: Linux follows with its own compiler and the same steps.
+- The installer steps contain no Win32 calls; only the window's DPI awareness (`installer/dpi.py`) is Windows-only, and
+  it does nothing elsewhere. Linux runs the same steps with its own compiler ("Linux release").
 - The keys file path is passed to the tools; key values never appear in the UI, logs or files.
 - The window is a front end over the CLI (`python -m installer --base ... --update ... --keys ... --lang ... --dest
  ...`), which prints one JSON progress event per line. Tests and CI use the CLI.

  which file is damaged.
 - Unsigned exe: SmartScreen warns on first start.
+- NSZ and XCZ input (game files compressed by the nsz tool: NCAs stored as NCZ, their sections decrypted and
+  compressed with zstd): the check step tells them by their content, not their name (an NSP or XCI holding NCZ files),
+  so the file dialog has one filter for all four. It unpacks each into `<temp>/unpacked/<base|update>.nsp`
+  (`tools/ncz.py`), an NSP of the NSZ's files or of the XCZ's secure partition, and the extraction reads that.

+# Mods
+
+TotK Recomp loads the mods players make for the Switch emulators (Ryujinx, yuzu and its forks): texture and model
+packs, gameplay and text changes from GameBanana and similar sites, TKMM's merged output, code patches (`.ips`,
+`.pchtxt`) and Atmosphère cheat files. No mod or cheat file ships with the port.
+
+## Install a mod
+
+1. Open the settings menu (F1, Esc, or Minus and Plus together on a controller), go to the Mods tab and choose
+   **Open mods folder**. That is the `mods` folder next to `totk.exe`; the menu creates it when it is missing.
+2. Make one folder per mod in it and unpack the mod's archive into that folder. The mod's own folders (`romfs`,
+   `exefs`, `cheats`) must sit directly inside the mod's folder:
+
+   ```
+   mods\
+     Better Grass\
+       romfs\
+         ...
+     Fast Travel Anywhere\
+       exefs\
+         patch.pchtxt
+     My cheats\
+       cheats\
+         277178B7DBA1B6D4.txt
+   ```
+
+   An archive laid out for a Switch SD card or an emulator works as it is. Inside the mod's folder the port also finds
+   `atmosphere\contents\0100F2C0115B6000\romfs`, `contents\0100F2C0115B6000\romfs` and `0100F2C0115B6000\romfs`, the
+   same places for `exefs` and `cheats`, and `atmosphere\exefs_patches\<name>\` for code patches.
+3. Start the game. A mod that patches the game's code makes the game rebuild itself first (see Code patches below).
+4. Open the Mods tab to check the mod. Each row says how many game files the mod replaces and adds, how many cheats it
+   brings, and why a part of it is not used.
+
+## Order and switches
+
+The Mods tab lists every folder in `mods`. Select a mod and press A or Enter to switch it on or off. The top face button
+or Ctrl+Up moves it up, the left face button or Ctrl+Down moves it down. When two mods change the same file, the
+higher one wins; the lower mod's row says how many of its files the higher one covers. Changes apply after a restart.
+
+The menu saves the order and the switches in `totk.ini`, under `[mods]`, by folder name: `mods_order` and
+`mods_disabled`. A folder the list does not name yet, such as a new or renamed one, goes below the named ones.
+
+### Mods that change the same files
+
+Two mods that edit the same game file do not combine: the higher one wins the whole file. Merge such mods with
+[TKMM](https://github.com/TKMM-Team/Tkmm) (TotK Mod Manager) and set its export location to an empty folder inside
+`mods`, for example `mods\TKMM`. The exported folder then counts as one mod here. Mods packaged for TKMM only
+(`.tkcl` files) go the same way.
+
+The port merges the resource size table on its own: at every start with mods on, it combines the tables the mods ship
+and raises the entries for files a mod made larger or added, the files inside a mod's packs (`Pack\**\*.pack.zs`)
+included. A separate RESTBL mod is not needed. The table tells the game how much memory each file needs: a file that
+outgrew its entry crashes the game when it loads, which can be long after the start, when the game first needs it. The
+log line `RomFS: resource size table: ...` says how many entries were raised and names the first files inside packs.
+
+## Code patches (ExeFS)
+
+A mod with `.ips` or `.pchtxt` files patches the game's code. A patch is for one game update: an `.ips` file is named
+after the build id of the update's code, a `.pchtxt` file names it on its `@nsobid` line. The game's code is compiled
+ahead of time, so these patches are built into `totk.exe`:
+
+1. The first start after such a mod is added closes the game and opens the setup's rebuild window. The rebuild takes
+   a few minutes (the shaders stay prepared), then the game starts again. Saves and settings are kept.
+2. Until the rebuild succeeds, the whole mod stays off, its other files included.
+3. After the rebuild the mod switches on and off from the Mods tab like any other, without another rebuild.
+
+The rebuild needs the setup folder the game was installed from. When that folder was moved or deleted, run
+`TotK-Setup.exe` again on the same install folder: it does the same job. `mods_rebuild = off` under `[mods]` in
+`totk.ini` turns the automatic rebuild off.
+
+A code patch over one of the port's own patches (the 60 FPS patch, the resolution patch and the other entries under
+**Built into the port**) turns that built-in patch off while the mod is on. The mod's row names it.
+
+A patch file may also change the game's data (constants and tables in its `.rodata` and `.data`). Those bytes are
+stored into the loaded game at start, before it runs. When two mods write the same bytes, the higher one wins,
+as with files.
+
+## Cheats
+
+A cheat file is part of a mod: `mods\<mod>\cheats\<build id>.txt`, switched cheat by cheat on the Cheats tab. Cheats
+that change the game's code need the same rebuild as code patches. [cheats.md](cheats.md) explains the file names for
+each game update, the rebuild and which cheats cannot run.
+
+## Renaming a mod folder
+
+The port keys a mod by its folder name. A renamed folder counts as a new mod:
+
+- it moves below the mods the list names, and comes back switched on;
+- its cheats come back switched off;
+- its code patches and code cheats are built again, so the next start runs the rebuild.
+
+Rename mod folders before you set them up in the menu, not after.
+
+## HD texture packs
+
+Texture packs made for the emulators replace the game's textures with larger ones, so the heap the world's textures
+stream into must grow. Such a pack grows it in its own `System/HeapSize/Product.Nin_NX_NVN.HeapDef.byml.zs`, sized for
+the emulators' 8 GB memory option. The port reads that file at start: the texture heap and the game's memory pool grow
+by the pack's amount, and the game gets the port's own heap table with that growth (the log says
+`resolution: mod <name> ships a HeapDef with TextureHeap ...`). Nothing needs to be set. For a pack without such a file
+that still loops the panic Blood Moon, set `tex_heap_extra_mb` under `[mods]` in `totk.ini` (0 to 4096 MiB).
+
+Tested: **HDPacks.com Tears of the Kingdom 4K Texture Pack v1.0** (`4kTextures`, 10,407 textures, 6.5 GB) on game 1.4.3
+and 1.2.1, RTX 4080 SUPER: it loads into the game from a save and runs at the same frame rate, with about 3.3 GB more of
+textures in memory (4.5 GB of game memory pools against 1.2 GB without it). Other packs are not tested and come with no
+guarantee. Such a pack needs a lot of video memory; on a GPU with less than 8 GB, `astc_bc = 1` under `[performance]`
+keeps its textures at a quarter of the size.
+
+## What does not work
+
+| On the Mods tab | Why | What to do |
+|---|---|---|
+| This folder has no romfs, exefs or cheats files. | The archive was unpacked one level too deep (`mods\Mod\Mod\romfs`), or it holds no game files. | Move the folders up so `romfs` sits directly in the mod's folder. |
+| ... files are made for another game version and are left out. | The mod's files carry another update's version in their names (`.Product.<number>.`). | Download the mod's release for your game update. |
+| Its code patches (exefs) are made for another game version. | The patch files name another update's build id. | Same: get the release for your update. |
+| This mod brings its own game code (a subsdk plugin or a replaced main). | Mods such as UltraCam ship compiled Switch code. The port cannot load it. | No workaround; the whole mod stays off. |
+| This mod patches the game code (exefs) in a way the port cannot apply. | The patch writes the game's data, not its code, or changes code in a form the port cannot build. | No workaround; the reason follows on the row. |
+| The folder name contains \|. | The mod list uses `\|` between names. | Rename the folder. |
+
+A mod never stops the game from starting. Whatever the port cannot use is left out and shown on the Mods tab.
+
+## When something looks wrong
+
+1. Switch the newest mod off on the Mods tab and restart. If the problem goes away, check that the mod is made for your
+   game update and does not fight another mod over the same files.
+2. `logs\totk.log` next to `totk.exe` names every mod at the start (lines starting with `mods:`), the cheats
+   (`cheats:`) and the resource size table (`RomFS: resource size table:`). Open log folder on the Advanced tab of
+   the menu shows the logs.
+3. When reporting a problem, attach `totk.log` and list your mods with the links you downloaded them from.

+# Rules for taking a PR
+
+## 1. What to review first
+
+1. Fixes before features. A PR that fixes a bug, a glitch or a crash goes first; feature PRs wait.
+2. Order fixes by reach: how many players the bug hits and how badly. Windows and default settings first, rare
+   hardware and unusual setups later.
+3. Scale the depth of the checks to the reach. A crash many players hit and anything on the frame path get the full
+   checks. A rare case (a CPU without AVX, an unusual setup) gets the minimal fix, one targeted check and a short
+   note. A crash fix on rare hardware is still worth taking: cut the checks around it, not the fix.
+4. Before testing, find out where the bug reproduces: OS, GPU vendor and generation, game version, settings. If the
+   symptom cannot appear on the hardware at hand (an NVIDIA paging bug on an AMD machine), say so and do not run
+   tests that cannot decide it.
+5. Check a feature PR against the designs in `docs/milestones/`. A feature with a design (mods, cheats) goes in as
+   part of that design.
+6. Several PRs on one topic: compare them before taking either. Another PR may already do it right.
+
+## 2. How to read the diff
+
+- The author's claim is a hypothesis. Read the whole diff: races, wrong semantics, edge cases, leaks, lock order.
+- Check the behaviour against evidence: how yuzu, Ryujinx, LAS Recomp, SavageWindRecomp, nxnative and MacNativeGames
+  do the same thing in `refs/` (`tools/fetch_refs.sh` recreates it); the Vulkan spec; hardware docs
+  ([docs/maxwell.md](../../docs/maxwell.md)); upstream issues.
+- Weigh two things for every change: its cost on the hot path, and how it fails (device lost, hang, stale data, weak
+  or non-AVX CPUs, other GPU vendors, Wine/Proton).
+- Read the code a hypothesis depends on before running the game: the game's functions in Ghidra or
+  `generated/<ver>`, our path in `runtime/`. A run confirms what the code could not rule out. It is one run, not a
+  series of variants.
+- Order the work so the cheapest check that could refute the PR's idea runs first. Refuted: stop, write down why,
+  no build, no benches.
+
+## 3. What a PR needs
+
+- **Proof.** The bug reproduced before the fix, the same repro after, both results side by side: a screenshot, a log
+  line, a probe, a differential test. A fix without a reproduced failure is not proof. Where a repro is impossible
+  on the hardware at hand, say so; the fix is then taken only on strong static evidence in the code. Where a repro is
+  risky (device lost or a TDR can hang the machine), write the recipe and let the owner decide.
+- **Frame-path changes** get whole runs of the heavy scene with the switch off and on, at least two each
+  ([02-performance.md](02-performance.md)). Zero new slow frames is a hard bar.
+- **A switch.** A change on the hot path or in rendering sits behind an env or `totk.ini` switch, so a player can turn
+  it off and we can compare.
+- **Nothing changes for players outside the feature.** The DLSS PRs touched shared code; they went in once every
+  path that runs without DLSS was gated on DLSS being on.
+- **A fix for one setup keeps the default for everyone.** The PRs that raised the low memory block from 6 to 10 GiB for
+  all players were rejected; the right shape is 6 GiB plus the extra where it is needed.
+- **Parts we cannot run** (Linux-only code, an HDR display, RTX-only paths) are gated so they cannot touch anyone
+  else, or wait for a report from someone with that hardware. Note them as unrun.
+- **Project tests** from [03-correctness.md](03-correctness.md): lifter differential tests, probes, `--selftest`,
+  `tools/check_content.py --staged`.
+- **Text the player sees** goes into the catalog: `runtime/ui_text.h` ids and `runtime/ui_text.c` entries in every
+  language the menu has (English, Russian, Brazilian Portuguese, Simplified Chinese), and `installer/text/*.json` for
+  the installer. No hardcoded sentences, no second string table.
+- **A new setting** is described in `totk.ini.example` and [docs/settings.md](../../docs/settings.md).
+- **Licences.** MIT, BSD, ISC, zlib and Apache-2.0 code may be copied, with its header and a row in
+  `THIRD_PARTY_NOTICES.md`. yuzu, suyu and other GPL code is read for behaviour only; we write our own.
+
+## 4. Reasons to reject or rework
+
+- No test or repro for a change that is not trivial.
+- Slow: a state copy per draw, a global atomic counter on the hot path, synchronous file I/O or a GPU allocation on a
+  game or render thread, new slow frames.
+- Changes behaviour for everyone to serve one setup, or is on by default without a run in a scene where it acts.
+- "Fixes" a crash by turning a feature off for a vendor. A crash that goes away with a feature off points at the bug;
+  the feature gets fixed.
+- Breaks another feature (a preview that loses anti-aliasing).
+- Fake features: labelled FSR4 or frame generation, and not that.
+- Wrong measurements: percentiles over window means, counters over the wrong set.
+- Generated C edited by hand instead of the generator (`recomp/`).
+- A disallowed licence or pasted GPL code.
+
+## 5. Finishing a good PR
+
+A good PR that misses the project's scheme (hardcoded text, conflicts, layout, comment style) is brought to it while
+merging, not sent back to the author for another round. When only part of a PR is good, take that part and note what
+was left out and why.
+
+A bug found outside the PR under review is not fixed on the spot: search the open PRs on that topic, report the bug
+with them, and let the owner decide.
+
+## 6. Merging, branches, commits
+
+- Each PR or wave of PRs gets its own branch `task/<tag>` from a fresh `dev` and its own build dir. It merges into
+  `dev`.
+- Once the review is done, the symptom is gone on one paired shot and the probes pass, merge into `dev` and hand the
+  build to players: they test in game faster and wider than our routes. The wider checks (other routes, validation,
+  fps cost) follow as a separate diff. Speed never skips the review of the diff itself.
+- `main` only with the owner's explicit yes. Push only when told to.
+- A commit message is a plain English sentence, no `feat:`/`fix:` prefixes.
+- The version lives in the repo-root `VERSION` file; the owner decides when it moves.
+- After a merge, record which PRs went in, what was reworked, what was rejected and why. The reason for a rejection
+  goes into the PR as a plain English comment.

+# Performance: no lost frames on weak hardware
+
+## Who we tune for
+
+- The goal is many more fps on modest hardware, and Steam Deck later (Zen 2 4c/8t APU, shared LPDDR5, the exe runs
+  through Proton/Wine).
+- The developer's machine (Ryzen 9 7900X + RX 9070) is fast and its numbers do not carry over. A laptop with an
+  i7-9750H and a GTX 1050 Ti is a sample of a weak machine, not the target to fit constants to.
+- What weak hardware measured:
+  - GTX 1050 Ti (4 GiB, 214 MiB BAR, no ReBAR): the GPU read imported host pools over PCIe, 110-120 ms a frame
+    against 4.3 ms on the RX 9070. The VRAM mirror brought it to 10-11 ms; that machine is now CPU-bound at 25-45 fps,
+    replay 25-30 ms a frame.
+  - The same write-watch scan costs about 3x the CPU time there.
+  - NVIDIA and desktop AMD GPUs have no ASTC: textures decode in a compute shader. CPU decodes before that made
+    0.4-0.7 s load frames on the 1050 Ti.
+- Wine emulates `GetWriteWatch` with `mprotect` and a fault per first write. Anything relying on cheap OS memory
+  tricks (write-watch, `VirtualProtect` freezing, fault handlers) is checked against Wine's implementation.
+- The port uses about half of even a weak CPU, so the frame's critical path is the limit, not throughput. TotK keys
+  per-core data by `GetCurrentProcessorNumber` without locks, so the game's threads share three virtual cores on any
+  host. In a fight the main thread and five job workers keep 2.6 of the 3 busy: guest code speed sets the fps.
+- Perf work builds and measures 1.4.3. A 1.2.1 build is for a change about to merge with a large gain.
+
+## Gain ceiling first
+
+Before writing or taking a perf change, compute its ceiling: the share of the code it removes times the share of the
+frame that code holds on the critical path, on weak hardware. A ceiling of a few percent or less is not worth it.
+
+- Use the critical path (`TOTK_CRIT` + `tools/crit_path.py`, heavy frames only), not one thread's profile. On the weak
+  laptop the submit thread is 55% replay, yet the critical path of heavy frames is 67% guest code, 15%
+  `nvnSyncWait`, 13% core waits and wake latency.
+- Changes that can move the frame by 10% or more are usually design changes. Polishing a hot function from a flat
+  profile almost always gives zero.
+
+## A neutral safe change stays
+
+An optimization that measures neutral on the fast machine stays on by default when:
+
+- upstream (`refs/`, other ports) reports a gain for it, especially on weak CPUs or GPUs;
+- the static read leaves no hazard, and the probe or differential test passes;
+- whole heavy-scene runs off/on x2 show no fps loss and no new slow frames;
+- a switch turns it off.
+
+"No gain here" is not a reason to drop a safe change with upstream evidence. A regression or a hazard nobody ruled
+out is.
+
+## How to measure
+
+- **By game time, never by frame counts.** Run length, analysis windows, A/B blocks and input scripts go by the world
+  clock (`--seconds`, `TOTK_CRIT=w<lo>-<hi>`, `TOTK_PROFILE_FRAMES=w<lo>-<hi>`, `TOTK_SHOTS=w<lo>-<hi>:<step>`). The
+  same frame count at another fps is another scene.
+- **Check a scripted run reached the world.** Title menus on a slow boot eat button presses; confirm the run is in the
+  world before trusting its numbers.
+- **Whole runs off and on, two each at least.** An in-run A/B on a moving scene lies: the A and B blocks land on the
+  same game seconds every run, so a content difference repeats. One in-run A/B showed "-11% replay"; whole runs gave
+  5.84/5.73 against 5.76/5.73 ms, nothing. In-run A/B only on a static scene (standing still).
+- **Spread.** One script on near-identical builds gave 1% lows from 31.5 to 50 fps. Compare medians of three runs,
+  never one run against one run.
+- **A quiet machine.** `tools/run_game.py --quiet` takes the machine-wide lock; no other `totk.exe`, build or test runs
+  meanwhile. One game at a time.
+- **A warm shader cache, prepared properly.** Shader and pipeline caches are not copied between build dirs:
+  `totk.exe --prepare-shaders` or `--warm-shaders` in that dir. The AMD driver cache is keyed to the exe path and
+  limited in size: preparing another build dir can evict this one's libraries (40-220 ms per new effect in play).
+- **A heavy scene.** A fight with a large enemy and a crowd, fps limit at the maximum (`TOTK_FPS_LIMIT=360`). Compare
+  one shot with the scene's reference before trusting numbers.
+- **No base runs by habit.** Run the candidate alone and judge it against the targets: max fps, zero slow frames
+  (`perf: slow frame`), no black or flat frames, no new validation errors. Glitches are found by looking at shots and
+  frame dumps, not by diffing metrics. Run a base build only when a specific question needs a side-by-side.
+
+| What | How |
+|---|---|
+| fps, worst frame, render-thread buckets, GPU busy, VRAM | `--env TOTK_TRACE=perf,sched`, then `python tools/perf_summary.py <log> <lo> <hi>` |
+| the frame's critical path | `TOTK_CRIT=w<lo>-<hi>` + `TOTK_CRIT_OUT=<path>`, then `python tools/crit_path.py <file>` |

+| VRAM pressure on a large card | `TOTK_VRAM_LIMIT_MIB=<MiB>` caps the budget the port sees |
+
+## What the hot path must not do (Windows host)
+
+- **Files.** The game threads (main, job workers) and the render thread never open, read, write or flush a file, and
+  never wait for a thread that does. Opening a 20-byte file in a 139k-file folder: 0.1 ms idle, 11-40 ms in play while
+  the translator, the pipeline cache and the save wrote to the same volume. A save's `FlushFileBuffers` and
+  `MOVEFILE_WRITE_THROUGH`: 93-135 ms. Saving the pipeline cache under its lock on the present thread froze the replay
+  every 20 s. File I/O goes to a background thread; results come back in memory.
+- **Waits.** Short waits spin on the counter; waits over 1 ms use the high-resolution timer. A waitable timer wakes
+  0.3-0.5 ms late; the SDK's 20 us sleeps took 460-515 us. A 1 ms timer thread does not help: it gave more slow frames.
+- **GPU allocations.** VMA's `vkAllocateMemory` of a 256 MiB block under its lock: 8-23 ms. A new block on the render
+  thread is a hitch.
+- **128-bit division.** `(unsigned __int128)t * num / den` compiles to the library call `__udivti3`; counter
+  conversions that way took a tenth of the game threads' time in a fight. Use the precomputed scale (`platform.h`
+  `PlatScale`).
+- **Per-draw copies and counters.** A pipeline-state copy per draw, a global atomic counter, a scan of every page each
+  frame: on a weak CPU each is frames.
+- **Memory kept per frame.** Anything allocated per texture initialization or per frame must be freed. One copy kept
+  per texture init grew host memory by ~44 MiB a game minute until a commit failure after hours (#670). Check private
+  memory over a few idle minutes for a PR that stores per-object state.
+- **Scheduling.** Any timing or scheduling change is checked for slow frames. A preempt check at every host call made
+  one bug rarer but added 50-75 ms CPU hitches and was reverted.

+# Correctness: checks that keep behaviour intact
+
+## Lifter and generated C
+
+- Generated C is never edited by hand: change the generator in `recomp/`.
+- `recomp/layout.py` alone decides module bases.
+- Every change to the lifter or the CPU headers (`runtime/cpu.h`, `runtime/simd.h`) passes the differential tests
+  against Unicorn, all run with `.venv`:
+
+| Test | Checks |
+|---|---|
+| `tests\diff\lift.py` | instructions sampled from the modules; `--coverage` lists the words the lifter rejects |
+| `tests\diff\simd.py` | the whole FP/SIMD encoding space |
+| `tests\diff\atomic.py` | exclusive load/store and ARMv8.1 atomics |
+| `tests\diff\func.py` | whole functions as the generator emits them: loops, jump tables, calls |
+| `tests\flags_check.py` | the function-local flag helpers against the packed ones |
+| `tests\excl_mt.py` | the exclusive monitor under contention and ABA, on several threads |
+| `tests\jumptables_check.py` | `recomp/jumptables.py` against Unicorn: 0 disagreements on 1.2.1 and 1.4.3 |
+
+- A `--cpu v2` build (no AVX2) passes the same tests with `--cflags=-march=x86-64-v2`. Players without AVX exist.
+- A compile error in generated C on a line the generator could not have written is a bit flip on disk or in memory.
+  Regenerate and compare hashes; leave `recomp/` alone.
+
+## Runtime
+
+- From the build dir: `totk.exe --selftest`, `--probe-kernel`, `--probe-vkexec`, `--probe-nvn-tex`, `--probe-shader`
+  pass.
+- Settings: `totk.exe --probe-cfg` and `python tests\settings_doc_check.py`.
+- Button prompts: `.venv-py314\Scripts\python tests\romfs_prompts_test.py`. Build dirs carry only `romfs-patches`; to
+  test PC or Xbox prompts in game, generate the overlay first:
+  `.venv-py314\Scripts\python tools\make_romfs_patches.py --version <ver> --prompts pc --out build\<dir>\romfs-patches-pc`,
+  then restart the game.
+- Installer: `tests\installer_gui_test.py` (event model, form, catalogs, cancel, display scale).
+- Shaders: `tools\shader_census.py --version <ver> --translate`, `tools\xlate_smoke.py`. A translator patch
+  (`tools/xlate/patches/`) needs `build/xlate` rebuilt and changes shader hashes: anything keyed to a shader hash
+  breaks with it.
+
+## GPU portability
+
+- New Vulkan code queries the feature, extension, format or limit it uses and keeps a working path or a logged
+  fallback without it (provoking vertex and subgroup size pinning in `vk_pipeline.c` are examples).
+- Never hardcode what one GPU reports: alignments, subgroup size (RDNA4 may run wave64, old AMD Vega is wave64 only),
+  depth formats, `maxPushDescriptors`.
+- One queue: every submit and present takes `vk_queue_lock`. Presenting from its own thread on a second queue gave
+  device lost on GTX 10-series in another port.
+- RDNA1/2 bugs do not reproduce on RDNA4 (another driver branch); NVIDIA bugs do not reproduce on AMD. A Ryzen 7000
+  iGPU is RDNA2 and runs the RDNA1/2 driver branch: a cheap testbed for those reports.
+- Validation: a `--validation` run in the world shows no new messages.
+
+## Maxwell / NVN behaviour
+
+The port must do what the Switch GPU does, not what Vulkan does by default. The full list with sources:
+[docs/maxwell.md](../../docs/maxwell.md), section 7. The traps a PR breaks most easily:
+
+- Provoking vertex: Vulkan takes the first vertex, NVN the last.
+- Unwritten vertex outputs read (0, 0, 0, 1).
+- A colour target outside the fragment shader's output map keeps its texel (write mask 0). AMD writes garbage there.
+- Feedback loops: the G-buffer pass reads its own targets. It needs the feedback layout and a by-region barrier.
+- Depth bias argument order, depth mode, depth clamp: checked against deko3d.
+- Report timestamps: the engine's GPU time comes from them, and dynamic resolution and game speed follow it.
+
+## Timers and the real-time step
+
+- With `realtime` set, the game steps by a measured ratio, not whole 30 Hz units. A countdown remainder in
+  (0, FLT_EPSILON] is never stepped again, and a consumer testing `> 0` sees it active forever. That was "weapons
+  cannot be changed after a Fuse until a reload" (#18).
+- Symptoms of this class: stuck until a reload or teleport, locked after an action, works sometimes.
+- A PR touching the frame step, the pacer or the fps limit is checked for this class.
+
+## Threads and scheduling
+
+- ARMv8 `stlr` then `ldar` is ordered (RCsc); C11 release/acquire lets x86 reorder that store and load. Changes to
+  the lifter's barriers or atomics pass `tests\diff\atomic.py` and `tests\excl_mt.py`.
+- A scheduler change is judged from one `TOTK_TRACE=sched` run by how long a ready, better thread waits for a core it
+  may use, plus the slow-frame count. Not by statistics over many runs.
+- A crash that looks like a race: rule out the save first. One reported crash was the save itself; it crashed the
+  same way on a real Switch.
+
+## Files and caches
+
+- A crash leaves zero-filled files. Caches are validated on load, not trusted because they exist.
+- The pipeline cache is dropped when vendor, device or `pipelineCacheUUID` change.
+- Unicode paths: W APIs with UTF-8 to UTF-16 conversion.
+- A failure that happens once and does not come back: rerun before debugging it as a code bug. Broken caches and bit
+  flips happen.
+
+## Game content boundary
+
+- The repository is public. No game files, and nothing extracted or generated outside `build/` and `generated/`.
+- Keys never appear in logs, commands, files, issues or comments.
+- Every file the generator emits carries the `GENERATED_MARKER` defined in `tools/check_content.py`.
+- `python tools/check_content.py --staged` before every commit. CI runs the same check.

+# Knowledge base
+
+Before investigating a symptom, or trusting a PR that "fixes" it, look for it here. Search by what the player sees
+(black, magenta, flicker, slow motion, missing, stale, streaks) and by the object (sky, grass, shadow, fog, HUD).
+
+## Invariants of recent changes
+
+A PR that touches these areas must keep them.
+
+- **Queue order.** When anything is submitted, every earlier part is already on the queue. Present, uploads, readbacks
+  from guest threads and the `vkDeviceWaitIdle` sites rely on it. The recorder thread now begins, ends and submits
+  the parts it records; the submitting thread still waits for that submission, so the order holds.
+  `TOTK_REC_END=0` restores the old split.
+- **GPU-written memory is never frozen.** Storage-buffer stores, copies and fills land in imported guest memory
+  without a fault or a write-watch bit, so a region only the GPU writes looks idle. Such regions are never frozen
+  read-only, and a frozen region is thawed before a GPU write. LAS Recomp never changes the protection of imported
+  memory because of NVIDIA. A suspected cause of NVIDIA "write invalid" device faults (#788, #802), not proven.
+- **VRAM pressure.** Under pressure, released textures whose storage the game has given to another texture go first:
+  30 s after release and once no finalized slot has bound them for 600 submits. Clean mirrored entries wait 5 s.
+  Both stop once use is back under the line. A PR touching texture lifetime is tested with `TOTK_VRAM_LIMIT_MIB`.
+- **Texture pins are freed.** Each pin counts the recording copies naming it and is freed 1200 submits after its last
+  use unless the replay holds it as a render target. Before that, pins leaked ~44 MiB a game minute (#670).
+
+## Fixed bug classes
+
+If a PR touches this code, confirm the fix still holds.
+
+| Symptom | Cause | Where the fix is |
+|---|---|---|
+| lime silhouettes in grass; rectangles in the sky | a target outside the output map must keep its texel; zero-filling it wiped the half-res depth | `vk_pipeline.c` `target_wmask` |
+| stale grass maps in the far terrain for a second after a hit | write-back of a texture the CPU had rewritten | `vk_texture.c` `write_back` |
+| cut grass stays standing; fire does not spread (#132) | CPU reads of GPU-rendered textures without an invalidate | `vk_texture.c` `vk_texture_write_back_small`, `nvn_ext.c` `nvn_pool_invalidate` |
+| cloud and fog volumes empty for the session | a one-shot draw skipped instead of waiting for its pipeline | `vk_exec_draw.c` `prepare_draw` |
+| tile rectangles | storage buffers bound by Ryujinx first-use order, not the c0 slot | `vk_exec_draw.c` `ssbo_slot` |
+| black dialog background and loading map | 3D targets rejected, the grading LUT never written | `vk_exec.c` `resolve_target` |
+| streaks on cliffs | primitive restart ignored | `vk_exec_draw.c` `restart_for` |
+| streaky map screen | the newest texture picked at shared storage | `vk_texture.c` `vk_texture_by_id` |
+| dark 16x16 blocks on the ground, sage spirit not drawn | G-buffer feedback loop | `vk_exec_draw.c`, `TOTK_FEEDBACK` |
+| magenta cave walls, brown sky | CPU-filled textures without a flush | write-watched mirrors, `vk_memory.c`, `vk_texture.c` |
+| black 3D scene | deferred texture binds | `nvn_api_cmd.c` `Bind*Deferred` |
+| HUD prompt boxes, black stamina wheel | `nvnTextureCompare` ignored the channel mapping | `nvn_api_obj.c` |
+| crash on world load | `GetCommandMemoryUsed` did not follow the driver's sizes; the game sizes model heaps from it | `nvn_api_cmd.c` |
+| 20 fps | a yield back-off starting before 2 ms | `kernel.c` SVC 0x0B: no back-off |
+| weapons locked after a Fuse (#18) | timer remainder in (0, FLT_EPSILON] with the real-time step | patch under the `realtime` setting |
+| magenta/blue garbage or device lost on RDNA1/2 (#5) | writes into 3D BC block views | in `dev` |
+| black window after a driver update | a pipeline cache from another driver | `vk_pipeline.c` drops the cache by UUID |
+
+## Known open risks
+
+A PR touching these needs stronger proof.
+
+- Buffer textures are not replayed and bind a stand-in: light and decal lists may read 0.
+- New GPU-only colour images start undefined; feedback effects may show garbage.
+- Clears with a partial channel or stencil mask are skipped (`W_CLEAR_MASK`, `W_STENCIL_MASK`).
+- 8-bit indices are widened on the CPU at record time; a copy in the same submission gives stale indices.
+- `UpdateUniformBuffer` is a copy between full barriers and ends the render pass (fps outdoors).
+- Report timestamps carry host time at fence completion: the engine's GPU time is wrong.
+- The game's SVC-free spin loops burn a host core (843 in `main`).
+- Images aliased onto one GPU-only pool allocation do not see each other's data on AMD.

+## Our mistakes, not to repeat
+
+- **"-11%" was an A/B artifact** of a moving scene. Whole runs off/on showed zero.
+- **Micro-optimizations from a flat profile** (1-3% of samples each) gave 26.2 against 26.4 ms on the weak laptop:
+  nothing. Nobody had computed a ceiling.
+- **A scheduler patch merged on run statistics** added 50-75 ms hitches. Slow frames are a hard bar.
+- **Ten game runs on lock theories** where one Ghidra read of the game's code narrowed it at once.
+- **45 minutes of builds and benches** on an idea its own first thread census had refuted: the game pins 53 of 56
+  threads itself. The cheapest refuting check goes first; when it refutes, stop and write the idea down.
+- **Tests of a bug that could not appear on the hardware at hand** (NVIDIA paging on an AMD machine): 245k tokens and
+  37 minutes for nothing. Ask first where the bug reproduces.
+- **Turning the recorder off for a vendor** instead of finding its bug. Stopped: the feature gets fixed, not silenced.
+- **Bisecting code when every build crashed the same way at once.** The cause was a bad page of a game file in the OS
+  file cache. When all builds fail identically, suspect inputs and caches first.
+- **A duplicate issue closed with a bare "Same as #N"** lost the logs and links. Move everything useful to the issue
+  that stays open first: hardware, driver, version, when it happens, workarounds, links from comments.

+- [ ] Hot-path cost: no file I/O, GPU allocations, waits, per-draw copies or global atomics on game or render threads.
+- [ ] No memory kept per frame or per object without a free.
+- [ ] Failure modes: device lost, hang, stale data, CPUs without AVX, NVIDIA/Intel/old AMD, Wine/Proton.
+- [ ] New Vulkan code queries the feature and has a fallback; nothing hardcoded for one GPU.
+- [ ] Invariants kept: queue order, GPU-written memory never frozen, VRAM pressure path, pins freed.
+- [ ] Players without the feature see no change. The default for everyone stays for one setup's sake.
+- [ ] New behaviour behind a switch. A new setting described in `totk.ini.example` and `docs/settings.md`.
+- [ ] Player-visible text in the catalogs, in every menu language (`runtime/ui_text.c`, `installer/text/*.json`).
+- [ ] Copied code: allowed licence, header kept, row in `THIRD_PARTY_NOTICES.md`. No GPL code.
+- [ ] Generated C not edited by hand.
+- [ ] Parts we cannot run (Linux, HDR, RTX-only) gated away from everyone else and noted as unrun.
+
+## Proof
+
+- [ ] Repro before the fix and the same repro after, side by side.
+- [ ] Lifter or CPU headers: differential tests against Unicorn; `jumptables_check.py` 0 disagreements.
+- [ ] Runtime: `--selftest` and the four probes pass.
+- [ ] Settings: `--probe-cfg` and `tests\settings_doc_check.py`. Prompts: `romfs_prompts_test.py`, overlay generated
+      for a game check.
+- [ ] Frame path: whole heavy-scene runs off/on, two each at least, by game time, quiet machine, warm cache prepared
+      in that build dir. No fps loss, zero new slow frames.
+- [ ] Rendering: shots or a frame dump in a scene where the change acts; no black or flat frames; no new validation
+      errors.
+- [ ] Perf PR: gain ceiling computed for weak hardware.

+- [ ] Taken, partly taken or rejected, with the reason written down and posted to the PR.
+- [ ] What missed the project's scheme brought to it while merging.

+# PR review kit
+
+Rules and background for a tester or reviewer who takes community PRs into `dev`. One goal: no PR breaks the
+game's behaviour or costs frames on weak hardware.
+
+## The short version
+
+1. A PR description and "works for me" prove nothing. Read the diff yourself and check it against `refs/`, the
+   Vulkan spec and upstream issues.
+2. Almost every change needs a test: a repro before and after, a probe, a differential test, or whole runs with the
+   switch off and on.
+3. The developer's machine is fast; players run weak machines. "Neutral here" says nothing about them, in either
+   direction.
+4. A player without the problem sees no change: the new path sits behind a switch and the old path stays as it was.
+5. Nothing goes into `main` without the project owner's explicit yes. Accepted work lives in `dev` first.

+# Settings reference
+
+`totk.ini.example` describes the settings for players. This page lists the rest: diagnostics, test hooks, paths and experiments. Set one as `name = value` in `totk.ini`, or as the environment variable `TOTK_NAME`, which wins over the file. Remove the line to go back to the default.
+
+## Safety
+
+- **Safe**: changes only what the row says, with no effect on stability or saves.
+- **Caution**: can slow the game, grow files, or change the picture, and undoes cleanly when removed.
+- **Risky**: can crash or hang the game, or break the picture or game logic, while it is set.
+- **Save risk**: can damage or lose saves, or point the game at other game or save files.
+- **Unknown**: the code did not settle it.
+
+Many rows below are developer tools that only act together with another setting or a command-line mode (for example a trace mode or the DLSS path). The row says so where the code does. The rows come from reading the code, and most effects have not been checked in a run.
+
+`tests/settings_doc_check.py` fails when a name in `known[]` (`runtime/cfg.c`) is described neither here nor in `totk.ini.example`, or when a default here differs from the code.
+
+## Diagnostics and logging
+
+| Setting | What it does | Effect of changing it | Safety |
+| --- | --- | --- | --- |
+| `astc_time` | `1` times the GPU dispatches of each ASTC texture decode and logs the time per block footprint and the largest call. | Adds GPU timestamp queries around every decode; if the queue has no timestamps or no `hostQueryReset`, the log says the decodes are not timed and nothing is measured. | Caution |
+| `bind_stats` | `1` counts bindings and descriptors per draw of each stage and how much of the bound state changes between draws. | Adds per-draw bookkeeping to the render thread and extra log output; frames get slower. | Caution |
+| `contact_debug` | `1` draws the contact-shadow factor in grey in place of the picture. | The frame shows a grey debug image while it is set; has no effect when contact shadows are off. | Caution |
+| `core_diag` | `1` records why ready guest threads wait for a virtual core and for how long, with a histogram every 60 presents. | Turns on host-call and SVC depth tracking and writes many log lines (one per present over 25 ms); frames get slower. | Caution |
+| `menu_cursor_log` | `1` logs what the menu cursor code reads at every screen change. | Only adds log lines. | Safe |
+| `perf_slow_ms` (default `50`) | Frames at least this many milliseconds long get a `perf: slow frame` log line with the time blocked per cause. | Changes how many frames are logged; a small value fills the log. | Safe |
+| `replay_check` | `1` reads every texture read-back a second time after a full drain of the replay queue and compares the two. | Stalls the replay queue at every read-back, so frames get much slower; mismatches are only counted and logged. | Caution |
+| `resolve_check` | `1` compares every cached pool lookup with the locked lookup and stops on a difference. | Slows every pool lookup; the game stops if the two ever differ. | Caution |
+| `speed_probe` | `1` adds the player's position and ground speed to the frame-rate line that `TOTK_TRACE=perf` prints every 120 presents. | Only adds log text; has no effect without `TOTK_TRACE=perf`. | Safe |
+
+## Profiling and measurement
+
+| Setting | What it does | Effect of changing it | Safety |
+| --- | --- | --- | --- |
+| `ab` | Splits game time into blocks of this many seconds in the order A B B A and lets settings written as `ab` take effect only in the B blocks. | Settings that accept `ab` flip on and off every few seconds, so frame times and the picture change with the block; without such a setting it does nothing. | Caution |
+| `crit` | `<first>-<last>` frame range (with `TOTK_TRACE=sched`) that records every state change and wake of the guest threads, then writes a file at the last frame. | Recording adds overhead to every thread switch in the range and writes one file; `tools/crit_path.py` reads it. | Caution |
+| `crit_out` (default `crit.bin`) | Path of the file that `crit` writes. | Only moves the file; nothing is written without `crit`. | Safe |
+| `profile` | Path of a sampling profile file; the profiler suspends threads to unwind their stacks. | Frames get slower while it samples and the profile file grows; `tools/prof_report.py` reads it. | Caution |
+| `profile_chains` | `1` keeps call chains of every thread in the profile. | Larger profile file and more work per sample; has no effect without `profile`. | Caution |
+| `profile_frames` | `<lo>-<hi>` samples only while presents lo to hi-1 are pending; `w<lo>-<hi>` uses world-clock seconds. | Limits the profile to a window; has no effect without `profile`. | Safe |
+| `profile_main` | `1` samples only the guest main thread. | Narrows the profile; has no effect without `profile`. | Safe |
+| `profile_render` | `1` samples only the render thread and keeps its call chains. | Narrows the profile and makes it larger; has no effect without `profile`. | Caution |
+
+## Capture and frame dumps
+
+| Setting | What it does | Effect of changing it | Safety |
+| --- | --- | --- | --- |
+| `dump` | Frame number to dump: every render pass target and storage image of that frame is copied out as PNG, with `passes.txt` and `images.txt`. | Writes many PNG files and shader hashes to disk and slows the dumped frame; size is capped by the dump code. | Caution |
+| `dump_buf` | `<addr>:<size>[:<off>:<stride>:<w>:<h>]` snapshots one GPU buffer range after every logged pass of a dump. | Writes `buf_<pass>.bin` files and `bufs.txt`; has no effect without `dump`. | Caution |
+| `dump_dir` (default `dump`) | Folder that receives the frame dump files. | Only moves the output. | Safe |
+| `dump_log` | Frame number; logs the frames from there up to the dumped frame into `passes.txt`, with PNGs only of targets up to 64K texels. | Writes a longer `passes.txt` and more PNGs; has no effect without `dump`. | Caution |
+| `flight_at` | Comma-separated frame numbers that trigger a flight-recorder dump. | Writes a dump folder when each frame is reached; has no effect unless the flight recorder (`TOTK_FLIGHT=1`) is on. | Caution |
+| `flight_dir` | Folder for flight-recorder dumps; the default is `flight` beside the folder of `totk.exe`. | Only moves the output. | Safe |
+| `flight_frames` (default `600`) | Number of presents the flight recorder keeps. | A larger ring keeps more history and more thumbnails in memory; has no effect unless `TOTK_FLIGHT=1`. | Caution |
+| `flight_thumbs` (default `1`) | `0` turns off the 320x180 thumbnail the flight recorder saves for each present. | Dumps hold only `frames.tsv`; thumbnails cost a GPU blit per present when on. | Safe |
+| `rdoc` | Comma-separated frame numbers to capture with RenderDoc, which is loaded before Vulkan starts. | The game runs under RenderDoc, with its capture options set to keep `VK_EXT_external_memory_host` available and to reference all resources, and captures are written to disk. | Caution |
+| `rdoc_dir` | Output folder for RenderDoc captures (the default is `build/captures`). | Only moves the output. | Safe |
+| `rdoc_dll` | Path of the RenderDoc library, for when it is not found by default. | A wrong path logs that the library cannot be loaded and no capture is taken. | Safe |
+| `shots` | `<lo>-<hi>:<step>` saves every step-th present in the range as `f<n>.png`, scaled to 480x270; `w<lo>-<hi>:<step>` takes them by world-clock seconds. | Writes one PNG per step and adds a readback of the window texture; the pictures clip highlights in HDR. | Caution |
+| `shots_dir` (default `.`) | Folder for the `shots` pictures; it is created when needed. | Only moves the output. | Safe |
+| `shots_full` | Set to any value to save `shots` at full size instead of 480x270. | Files get far larger and writing them takes longer; has no effect without `shots`. | Caution |
+
+## Automated tests and test hooks
+
+| Setting | What it does | Effect of changing it | Safety |
+| --- | --- | --- | --- |
+| `vram_limit_mib` | Pretends the device-local memory budget is at most this many MiB, for the paths that react to the budget (`tex_vram_pressure`, mirror refusal); the driver knows nothing of it. | Lets a large card drive those paths; a low value drops released textures and refuses mirrors that would have fit. | Caution |
+| `background_window` | `1` keeps the window behind the user's windows, never fullscreen at start, and F11 keeps its place; SDL windows ignore it. | The window does not come to the front or flash, so it is easy to miss; meant for unattended runs. | Caution |
+| `gpu` | `vulkan` or `null`: the graphics back end; `null` has no GPU, completes every submit at once and returns zeros for texture reads. | `null` shows no picture; any other value stops the start with an error. | Caution |
+| `input` | `none` reports no input from the keyboard, mouse or controllers. | The game gets no controller input and the menu cursor stops following the mouse; `input_script` still applies. | Caution |
+| `input_script` | Path of a file with lines `<frame> <button> [hold]` or `<frame> LSTICK or RSTICK <x> <y> [hold]` that are ORed into the real input. | The game presses those buttons by itself; a file that cannot be opened is logged and ignored. | Caution |
+| `menu_test` | `<frame>[:<frames per page>]` opens the menu at that frame, shows each tab for 30 frames (or the given count), saves one screenshot per tab and closes the menu. | The menu opens by itself and screenshots are written. | Caution |
+| `menu_test_dir` | Folder for the `menu_test` screenshots; the default is the working directory. | Only moves the output. | Safe |
+| `menu_test_set` | `<frame>:<key>=<value>[,...][;...]` changes settings live at that frame, with or without the menu open; `SAVE=1` also writes `totk.ini`. | Settings change during play without input, and `SAVE=1` rewrites the file. | Caution |
+| `probe_movie` | Text that picks the movie for `totk.exe --probe-movie`: the first file whose path contains it. | Only used by the movie decoder probe; ignored in normal play. | Safe |
+| `probe_movie_shot` | Path of a `.ppm` file that the movie probe writes the middle frame to. | Only used by the movie decoder probe. | Safe |
+| `probe_movie_bench` | `1` makes the movie probe also time the resampler that fits a movie to a game resolution of another shape, and print the time per frame. | Only used by the movie decoder probe. | Safe |
+| `swkbd_answer` | `<text>`, `<cancel>` or `<initial>`: answers the on-screen keyboard (for example a horse name) without opening a window. | The game gets that answer every time it asks for text. | Caution |
+| `swkbd_test` | `ok` or `cancel` opens the keyboard window and presses OK or Cancel on the first timer tick. | The keyboard window closes by itself. | Caution |
+| `test_pad` | `<lx>,<ly>,<rx>,<ry>` attaches a virtual gamepad whose sticks rest at these raw SDL axis values (-32768 to 32767). | The game sees a controller with that drift or deflection; a malformed value is logged and ignored. | Caution |
+| `test_prepare_shaders` | `1` translates every recorded shader on all usable CPUs during start. | Start takes longer and fills the shader cache folder; the CPU is fully used while it runs. | Caution |
+
+## Input
+
+| Setting | What it does | Effect of changing it | Safety |
+| --- | --- | --- | --- |
+| `bind_<button>` | Remaps one Switch button or stick direction to `pad:<name>` or `key:<name>` entries; covers `bind_a`, `bind_b`, `bind_x`, `bind_y`, `bind_l`, `bind_r`, `bind_zl`, `bind_zr`, `bind_plus`, `bind_minus`, `bind_left`, `bind_up`, `bind_right`, `bind_down`, `bind_lclick`, `bind_rclick`, `bind_lstick_left`, `bind_lstick_up`, `bind_lstick_right`, `bind_lstick_down`, `bind_rstick_left`, `bind_rstick_up`, `bind_rstick_right`, `bind_rstick_down` and `bind_shake`. | A line replaces every default of that button; button prompts in the game still show the default layout. The Controls tab of the menu writes these lines; `docs/controls.md` lists the entry names. | Safe |
+
+## Paths and files
+
+| Setting | What it does | Effect of changing it | Safety |
+| --- | --- | --- | --- |
+| `amiibo_dir` | Folder the Amiibo tab starts in; the tab saves the folder you last browsed here. | Only changes which folder the tab lists first. | Safe |
+| `exefs` | Folder of the game's ExeFS (with `main.npdm`); a relative path is relative to `totk.exe`'s folder. | Without it, an `exefs` folder next to `totk.exe` is used, else the path set at build time. The game code is compiled into `totk.exe`, and the loader checks the files here by SHA-256, so files from another build or game version stop the start with a message. | Caution |
+| `mods_dir` (default `mods`) | Folder that holds one subfolder per player mod, beside `totk.exe`. | Mods found there replace game files; see `docs/mods.md`. | Caution |
+| `mods_disabled` | Names of mods that are switched off, separated by `\|`. | Listed mods are not applied; the Mods tab writes this line. | Safe |
+| `mods_order` | Mod names, top first, separated by `\|`; the top mod wins a file that two mods replace. | Changes which mod's file the game gets; unlisted mods go below the listed ones, by name. | Safe |
+| `pipeline_cache` | Path of the Vulkan pipeline cache file (default `pipeline-cache.bin` beside `totk.exe`). | Moves the cache; a new path starts empty and pipelines are built again. | Caution |
+| `profile_dir` | Folder of the game profile, which holds the user account id that save data is named after; the default is a `profile` folder beside `totk.exe`, else the build-time path. | Another folder means a different set of saves. | Save risk |
+| `romfs` | Folder of the game's RomFS (with `romfs.bin`); a relative path is relative to `totk.exe`'s folder. | Without it, a `romfs` folder next to `totk.exe` is used, else the build-time path; a missing image stops the start with a message. | Save risk |
+| `romfs_index` | Path of `romfs-index.bin`, which `tools/romfs_index.py` wrote; the default is beside `totk.exe`. | The index is checked against the image by SHA-256 and size; a mismatch stops the start. | Caution |
+| `romfs_mmap` | `1` maps the RomFS image into memory instead of reading it with positional reads. | Changes how the image is read; the log reports when the mapped path is on. | Caution |
+| `romfs_mods` | Folder of an overlay with a `manifest.tsv` of sizes and SHA-256 hashes; its files are served in place of the originals. | A missing file, size or hash mismatch, or a changed original stops the start; player mods win over this overlay. | Save risk |
+| `romfs_patches` | Folder of an overlay with a `manifest.tsv`, served in place of the original files; the default is `romfs-patches` beside the index. | Same checks as `romfs_mods`; while it is set the Xbox and PC button prompts are off, and the menu says so. | Save risk |
+| `romfs_proof_dir` | Folder for the `.romfs-verified-v1` proof file of a full verification; the default is beside the index. | Only moves one small file. | Safe |
+| `romfs_verify` | `full` hashes the whole RomFS image at start; `force` hashes it again even when a proof file exists. | Start takes many minutes for a 17 GB image; a proof file is written so later starts skip the hash. | Caution |
+| `shader_cache` | Folder of the translated shader cache (default `shader-cache` beside `totk.exe`). | A new folder starts empty, so shaders are translated again during play. | Caution |
+| `shared_fonts` | Folder of the extracted system fonts; the default is `shared-fonts` beside `totk.exe`, else beside the RomFS. | Simplified Chinese, Traditional Chinese and Korean need these fonts: without them the game exits before its first frame in those languages. Other languages do not use them. | Caution |
+
+## Shader translation
+
+| Setting | What it does | Effect of changing it | Safety |
+| --- | --- | --- | --- |
+| `xlate` | Path of the shader translator program; the default is `totk_xlate` beside `totk.exe`, else under `build/xlate`. | Shaders are translated by that program; if it is missing the log says so and graphics shaders cannot be translated. | Risky |
+| `xlate_id` | Text or 64 hex digits that identify the translator build in shader cache keys; the default comes from an `.id` file beside the translator, else a hash of the program. | A value that two different builds share lets the cache serve shaders translated by the other build. | Caution |
+| `xlate_keep` (default `0`) | `1` keeps the translation job of a last-frame variant as `<key>.job` with its code. | Writes extra files to the shader cache folder; meant for running the translator by hand. | Caution |
+| `xlate_procs` (default `2`) | Number of translator processes allowed during play. | More processes translate new shaders sooner and use more CPU and memory; values below 1 count as 1. | Caution |
+
+## Graphics experiments
+
+| Setting | What it does | Effect of changing it | Safety |
+| --- | --- | --- | --- |
+| `block_views_3d` (default `0`) | `1` gives 3D block-compressed images block views too. | On some AMD cards a GPU write past the end of the image's memory loses the Vulkan device, and the game stops. | Risky |
+| `dyn_delta` (default `1`) | Records only the pipeline dynamic states (cull mode, depth and stencil tests, vertex input, blend enables, equations and write masks, ...) whose values changed since the last draw in the command buffer, also across pipeline changes; `0` records the full set at every change of pipeline state, as before; `ab` alternates with the `ab` blocks. | Fewer commands per pipeline change on the render and recorder threads; a driver that loses dynamic state across pipeline binds would draw with stale state. `TOTK_TRACE=perf` prints the calls and commands per submission. | Caution |
+| `feedback` | `0` samples a target that an earlier draw of the same pass wrote with no barrier; `restart` ends and restarts the pass behind a full barrier; otherwise the feedback-loop layout is used when the GPU supports it. | `0` brings back the old behaviour that the barrier fixed, so the picture can break in passes that read a target they draw into; `restart` costs extra passes. | Risky |
+| `flush_span` (default `0`) | `1` copies one span from the lowest to the highest flushed address of a pool, as an older version did. | Copies far more data to the GPU in crowded towns: an estimated 30-50 ms of GPU time per large copy over PCIe 3.0 x8. | Caution |
+| `freeze_idle` (default `60`) | Number of submissions a 2 MiB region stays unwritten before it is made read-only; `0` turns the freeze off. | A larger value keeps more regions writable and costs more write tracking; a write to a frozen region costs about 60 microseconds. | Caution |
+| `gpl_draw_build` (default `1`) | `0` leaves the missing shader libraries of a waiting draw to its background job instead of building them in parallel at once. | Draws whose pipeline is not ready are skipped meanwhile, until the job finishes. | Caution |
+| `lib_prebuild_keep` (default `0`) | Number of recorded graphics shader library variants that stay in memory after the boot prebuild. | Each kept library costs 140-460 KB of memory; the driver cache already makes a rebuild cheap. | Caution |
+| `minimal_layout` (default `1`) | `0` skips the compare against one-block tiles when a texture's memory layout is chosen. | The code calls it a negative control for fresh sessions; the comment does not say what the picture does. | Unknown |
+| `mirror_gap` (default `2`) | Hot pools at most this many 2 MiB regions apart share one write-watch query. | Changes the number of queries per submission; negative values count as 0. | Caution |
+| `movie_host` (default `1`) | `0` leaves every movie decoder to the game's own library. | The code comment says that library aborts at the first movie, so the game stops at the first cutscene. | Risky |
+| `movie_pace` (default `1`) | `0` hands every decoded movie frame over at the next present instead of when it is due. | Movies play at the game's frame rate rather than their own, so their speed no longer matches the sound. | Caution |
+| `pcss_k` (default `0.5`) | Depth-to-penumbra factor of soft shadows at 100 percent, for tuning. | Changes how wide soft shadows blur; has no effect while `pcss` is `0`. | Caution |
+| `pipe_sync` | Any value other than `0` or empty stops graphics pipelines from being built in the background. | Pipelines are built on the render path, which causes stutter when new effects appear. | Caution |
+| `push_stage` | `fs` pushes the descriptor set from the fragment stage instead of the vertex stage. | The log names the stage in use; the code does not say what changes in the picture. | Unknown |
+| `rec_end` (default `1`) | `0` lets the submitting thread begin, end and submit a recorded part again, as older versions did. | On some AMD cards the GPU hangs or the scene turns green and then white when a submission is split. | Risky |
+| `tex_vram_pressure` (default `90`) | Percent of the device-local memory budget above which released textures are dropped, 0 to 100; `0` is off. First those the game has overwritten with a later texture and left alone for 30 s, then those that can be uploaded again. | A low value drops textures sooner and re-uploads them; `0` keeps them and lets the card spill into system memory. Also a slider in the menu. | Caution |
+| `txd_transpose` (default `1`) | `0` turns off the swap of gradient components for gradient texture samples. | Terrain textures turned across the screen show crawling patches again. | Caution |
+| `ub_overlay` (default `1`) | `0` copies each uniform update inside a pass into its buffer at once, ending the pass with a full barrier; `ab` alternates with the `ab` blocks. | With `0` scenes with many updated blocks (the terrain, the sky islands) take longer on the GPU; `TOTK_TRACE=perf` prints how many updates stayed in their pass. | Caution |
+| `ub_overlay_out` (default `1`) | `0` copies each uniform update between passes into its buffer at once, behind a full barrier of its own; `ab` alternates with the `ab` blocks. Needs `ub_overlay`. | With `0` a run of updates before a pass costs a full GPU barrier each; `TOTK_TRACE=perf` prints how many updates between passes were overlaid. | Caution |
+| `ubo_snapshot` (default `1`) | `0` binds live memory for uniform blocks; `ab` alternates with the `ab` blocks. | Without snapshots late draws read another object's matrix, so objects can be drawn in the wrong place. | Risky |
+| `vk_no_float64` (default `0`) | `1` clears the 64-bit float feature, so the translator lowers FP64 to FP32. | Shaders change, so the shader cache entries for it are made again; precision of FP64 shaders drops. | Caution |
+| `vk_ssbo_align` (default unset) | Power of two that storage buffer offsets are treated as needing, to test the unaligned path. | The translator and the draw code round storage offsets down to it; shaders are translated again. | Caution |
+| `vk_subgroup` (default `32`) | Subgroup size to pin where the driver allows it. | A value other than 32 changes what the translator is told about the GPU, and shaders are translated again. | Caution |
+| `vram_headroom` (default `1`) | `0` turns off the spare half-block of video memory that a background thread keeps per memory type. | Texture allocations on the render thread can wait for a new block again. | Caution |
+| `vs_outs` | `all` declares all 32 vertex shader output locations; otherwise only the union of the paired fragment inputs. | Larger vertex shaders and new pipelines; unwritten outputs read the same as before. | Caution |
+| `wb_exact` (default `1`) | `0` decides write-back of GPU-written textures by page only. | A target that shares a page with data the CPU writes can go unwritten, so a name label next to the reticle can blink. | Caution |
+| `wb_merge` (default `1`) | `0` copies GPU-written ranges back as plain copies instead of writing word by word the words that changed. | In mirror memory mode the GPU's copy can overwrite words the CPU wrote, which breaks effects such as falling rain and waterfall splashes. | Caution |
+
+## Motion vectors and DLSS
+
+| Setting | What it does | Effect of changing it | Safety |
+| --- | --- | --- | --- |

+| `audio_off` | Any value mixes audio without opening an output device. | The game runs in silence and reports two channels; same as `audio = none`. | Caution |
+| `one_per_core` (default `0`) | `1` keeps the process on the first logical processor of each physical core; `ab` switches it with the `ab` blocks. | Busy threads stop sharing a core with a sibling thread, which can help or hurt on the CPU; it only applies when the CPU has hyperthreads. | Caution |

+Build or install on Linux ([installer.md](installer.md), "Linux release"), in Desktop Mode. The game then runs in either

+
+The game recognises the Deck (LCD and OLED) and uses its device profile for every setting `totk.ini` does not set:
+fullscreen, the screen's own 1280x800 (16:10: the camera and interface take that shape), the game's own 3D scale,
+vsync and a 40 fps limit. These are starting points, not measurements. What helps most:
+
+1. The performance overlay (F10, or both stick clicks L3 + R3) in full mode: the frame rate, mean and longest frame
+   time over a minute in Lookout Landing, in the Depths and in the Sky, with the settings named.
+2. The same with `fps_limit` 30, 45 and 60 and `render_scale` 50, 67 and game, so the defaults can be picked from
+   measurements. Steam's own performance overlay (the ... button) adds power draw and temperatures.
+3. LCD or OLED, SteamOS version (`uname -r` in Desktop Mode's terminal), and the game update.

+
+Windows draws a DPI-unaware process at 96 DPI and stretches its windows to the display's scale, which is what made the
+setup window blurry at 125% and above. gui.py calls enable() before it imports tkinter, so the process is system DPI
+aware before its first window exists; Tk then reads the display's DPI when it starts (`tk scaling` is 2.667 at 200%)
+and every font size in points comes out at the right size. The pixel sizes of the layout have no such scaling of their
+own, so gui.py passes them through px().
+
+System DPI awareness, not per-monitor: Tk 9.0.4, the one the release bundles, has no per-monitor support (its DLL
+imports no DPI-awareness function), so it draws everything at the system DPI. Per-monitor awareness would leave the
+window crisp on a display at another scale but with the primary display's font sizes; system awareness draws the

+// player's session). TOTK_DISCORD_APP_ID names the application whose name and artwork Discord shows — the default

+// art registers an application at discord.com/developers and puts its id in totk.ini — and TOTK_DISCORD_IMAGE the

+// re-reads the settings when cfg_version changes (a menu change reaches it within half a second), connects to the
+// first of Discord's discord-ipc-0..9 pipes that answers, and writes the activity again every 60 s: that write is
+// the keep-alive, and one that fails closes the connection and tries again 15 s later. Discord clears the status by
+// itself when the process ends and the pipe closes, so there is no shutdown path. Every answer frame is read and
+// discarded: unread, they would fill the pipe's buffer and block the client's writes.

+// merged into Switch npad button bits and stick axes. Button order follows libnx HidNpadButton (ISC). The key and pad
+// bindings are the tables in input_map.c (totk.ini overrides them). The keyboard and the mouse come from the window
+// system's back end (input_wsys.h: input_win.c with Win32, input_sdl.c with SDL), which also owns the cursor capture.
+// Keys and their map: docs/controls.md.
+// The gamepad also rumbles (input_rumble) and, when it has a gyro and an accelerometer, feeds the six-axis sensor from a
+// thread of its own (input_motion_start). Every SDL call on the gamepad is made under `lock`.
