The VM refused C0 (register conditional), so cheats like C046B400 FFFFFFFF were greyed out as unsupported. C0 now
runs with dmnt's operand types 0-5, widths and conditions; C1 and C2 save, restore and clear registers, C3 moves
registers to and from the static registers. tools/cheats.py gives the same opcode lengths and accepts the same opcodes.
skip() took the end of a nested block at depth 1 for the else of the failed outer block; it now counts depth the way
dmnt does, and 2x000000 is an else only for x = 1.
tests/cheats_vm_check.py runs tools/cheats.py and runtime/cheats.c on cheats of its own, the two from the issue
included.

A mod that patched the game code (.ips, .pchtxt) stayed off as a whole.
tools/exefs_patches.py now reads IPS, IPS32 and IPSwitch files from each
mod's exefs folder and from atmosphere/exefs_patches/<name>/. It keeps the
ones whose build id is main's and turns their writes into main's code into
one patch set per file. The writes go through the same rules as the code
cheats (tools/cheats.py convert). A file that writes main's data, or that the
rules cannot express, is unsupported as a whole. The setup's lift runs it
after cheats.py and writes build-cache/exefs.status.
runtime/mods.c checks each patch file against that status:
- a built file's set is switched on with its mod;
- a file the build lacks keeps the mod off and starts the rebuild at the next
start, like a code cheat does;
- an unsupported file keeps the mod off, and the Mods tab shows the reason;
- a file for another version is counted and left out.
A mod patch on a site of one of the port's own sets turns that set off while
the mod is on, and the Mods tab names it. The Mods tab also gets the "Rebuild
the game now" row.

Code cheats need the game lifted and compiled with them. Running the setup
again did that, but it lifted and compiled everything and prepared the
shaders again.
- The setup keeps the generated C and the objects in its temp folder (about
1.3 GB). gen.py rewrites only the chunks whose C changed, so Ninja
recompiles only those. One new code cheat on 1.4.3 took a 47 s lift and
19 s of compile and link on 24 cores.
- Prepare's key no longer follows the compile key, only the runtime, the
translator and the game version, so a rebuild keeps the prepared shaders.
- The cleanup writes build-cache/rebuild.txt, the command that opens the
setup window in a new --rebuild mode on the install folder. That mode runs
at once and starts the game again when it succeeds.
- At start, runtime/cheats.c runs that command and exits when an enabled
mod has code cheats the build lacks (plat_spawn, new for Windows and
Linux). build-cache/rebuild.skip keeps a failed or cancelled rebuild from
starting again for the same cheats. "Rebuild the game now" on the Cheats
tab tries again, and [mods] mods_rebuild = off turns the rebuild off.
Scripted runs never start it.

A cheat file is now part of a mod: mods/<mod>/cheats/<build id>.txt, or the
Atmosphere places inside the mod folder, the file name in any case. The port
ships no cheat files any more (the MyNXCheats files and their notice row are
gone).
- tools/cheats.py --mods builds the code cheats of every mod folder; a
cheat's key hashes "<mod folder>/<name>", so two mods' cheats of one name
keep their own switches.
- The setup reads the cheats from <install>/mods and writes the status to
build-cache/cheats.status.
- runtime/cheats.c reads the files of the enabled mods the port can use, in
the Mods tab order, and the status from build-cache.
- A mod with only cheats is usable. The Cheats tab groups the cheats by mod,
and the Mods tab says how many cheats a mod brought.
- The cheat texts are in all four menu languages.

Players bring their own cheats\<build id>.txt next to totk.exe; none ship with the port. The setup turns cheats that
write main's code into patch sets (tools/cheats.py), cheats that write data run in a cheat VM after dmnt's every
presented frame (runtime/cheats.c), and the menu's Cheats tab switches each one, saved under [cheats] in totk.ini.
The patch table now takes several sets per site, first set in file order winning, and replacements that end in a
branch or ret, so cheats that patch the same instruction or end in a jump can be built.
