- Eyes render under a VK_EXT_fragment_density_map: full rate around each eye's forward direction, 2x2 then 4x4 pixel blocks towards the edges ([vr] foveation = off|low|medium|high, default off). XR_FB_foveation cannot help here: the runtime's maps only shape passes drawing into its swapchain, and the eyes reach it through a copy. - aurora-main/patches/dawn/aurora_fdm.inc: Dawn enables the extension only on request and for dynamic rendering, flags every render pipeline, and chains an immutable RG8 map into any pass whose first color attachment is a view bound to one (ABI: include/aurora/dawn_fdm_abi.h). - android/Build-QuestDawn.ps1 builds the pinned Dawn revision with those patches for arm64 (dawn-build CI flags, protobuf off) into a cached package; Build-Quest.ps1 links it (-StockDawn opts out) and AuroraDawnProvider.cmake enables the ABI from its manifest. - lib/gfx/foveation.hpp generates the maps (32 px per texel, densities 255/127/63); an eye is foveated only when single_pass_eyes draws it in one render pass. Menus never are. - Live level from the headset panel's VR tab and the launcher; the launch decides whether the device has maps. debug.wiicompiled.foveation and debug.wiicompiled.fdm for A/B. - Tests: Foveation cases in gx_fifo_tests, mkw_vr_config_tests.

WiiCompiled VR for Meta Quest (Android)
Standalone Android/OpenXR build of the Mario Kart Wii recompilation for Quest 2,
Quest 3, Quest 3S and Quest Pro. The full design, build walkthrough and current
status live in docs/quest-port.md; this directory only
holds the Gradle project, its helper scripts, the game kit tooling
(QuestGameKit.psm1, Build-QuestGame.ps1), the on-headset build toolchain
(Prepare-QuestToolchain.ps1, toolchain/) and nod-jni.
powershell -ExecutionPolicy Bypass -File android/Prepare-QuestDependencies.ps1 # stages the SDL3 3.4.4 AAR once
powershell -ExecutionPolicy Bypass -File android/Build-Quest.ps1 -Install # the app, debug-signed, installs over adb
One app offers both games, with a toggle on Home: Mario Kart Wii and, when your
translation includes the mod, Retro Rewind. The translated game (the translator's
generated/ tree for your own PAL RMCP01 disc) is passed with
-Generated <dir>; it defaults to the installer workspace next to this checkout.
No game data is ever part of the APK, and neither is any translated game code:
the APK carries one game kit holding a recipe per game, and your libmain.so is
built from your own disc, either on the headset (Build on this Quest, about
half an hour) or on a PC and imported:
powershell -ExecutionPolicy Bypass -File android/Build-QuestGame.ps1 -Product base -Install
powershell -ExecutionPolicy Bypass -File android/Build-QuestGame.ps1 -Product retro_rewind -Mod <RetroRewind6> -Install
-Mod puts the Retro Rewind pack in the package; Import from computer takes
the same .wcgame from the Import folder. The headset can also fetch that pack
itself with Download Retro Rewind on Home, from Retro Rewind's own
distribution server, the way the PC launcher does.
Copy your disc image to the headset (for example adb push MarioKart.iso /sdcard/Download/) and press Select disc image in the launcher, which checks
and extracts it with nod, as the PC installer does. Or push an already extracted
disc to
/sdcard/Android/data/org.wiicompiled.quest/files/WiiCompiledOpenXRVR/DATA
Config.toml, saves and logs live in the same WiiCompiledOpenXRVR directory.
The app opens on a 2D launcher panel modelled on the PC launcher (WheelWizard VR):
Home picks the game with a toggle, starts it in the headset and says what is
still missing (the disc files, the game itself, or Retro Rewind's pack), and
Settings edits Config.toml (VR camera, render scale, virtual screen,
resolution, controllers, audio), with an Other tab for the files and the
games built from them, with a Reset installation action that removes the game files (and
on request the built games and the Retro Rewind pack) so they can be set up again, and an
About tab carrying the credits. The game itself is QuestActivity, in its own
:game process; adb shell am start -n org.wiicompiled.quest/.QuestActivity
still starts it directly.
