- From the rail ARMSX2 starts the game in its full-screen, controller-driven UI
and exits with it (-batch -bigpicture -fullscreen).
- bannerlator-pad-defaults: a PCSX2 player's settings and memory cards are
copied into ARMSX2 once; a new player starts on ARMSX2's first-time setup with
the BIOS folder in the ROMs folder (ps2/bios, created, or ps2/firmware), the
ps2 folder as the game list and the controller on Player 1; the guide button
opens the pause menu (how a rail game is left) instead of toggling analog.
Users bring their own BIOS and games.
- The catalog can name a file per memory page size ("pages"); the device's own
size picks it (ARMSX2 has 4K and 16K builds).
- On-screen controls: Auto keeps them off the desktop (the screen is a touchpad
there) and shows them for rail games and Steam when no controller is
connected; the drawer offers the setting in every session.
DroidDeck
Run Valve's native ARM64 Steam client on an Adreno Android device. Steam runs in a Linux runtime under proot, with gamescope and an in-app Vulkan compositor. Windows games use Valve's ARM64 Proton and FEX. A desktop with LXQt, Firefox, and emulators is also available.
Requirements and install
Use Android 9 or newer on a supported Adreno device (730 or newer, or 8xx). Mali, Xclipse, PowerVR, and Adreno 710 are unsupported. No root is required. Allow about 3 GB for the runtime and 1.1 GB more for the desktop and emulators. Install the APK from Releases, install the Linux runtime, then press Play and sign in. Steam downloads on first launch. Install Desktop & apps to use the desktop and emulators.
On Android 12+, if Steam exits without a log, turn off Restrict child processes in Developer options.
Build
Run tools/build_local.sh with Docker, Java 17, the Android SDK/NDK, and zstd installed. It builds the ARM64 audio sinks from PulseAudio 13.0 and packages them into the APK at app/build/outputs/apk/release/app-release.apk. Set DROIDDECK_PA13_SOURCE_DIR to an existing PulseAudio 13.0 source directory to skip downloading it. To install the APK on an attached device, run tools/deploy_local.sh.
Limits
Compatibility and performance vary by device; hardware validation is limited. Desktop compositing uses software rendering. Firefox sandboxing is reduced under proot. See the session logs in Download/DroidDeck/ when diagnosing problems.
