- New [vr] hand_tracking (default off, Quest only for now): the Quest launcher's Settings > VR and the headset panel's VR tab, under hand steering. Two XR_EXT_hand_tracking trackers are located every XR frame: with the controllers held the Quest builds the joints from their touch sensors (XR_EXT_hand_tracking_data_source's controller source), once they are put down from its cameras. The trackers exist only while the option and hand steering are on and also serve the runtime hand mesh; the extensions (plus XR_FB_hand_tracking_aim) are asked for when either is on at launch. - Aurora skins the runtime mesh with the joints themselves (tracked pose times inverse bind pose, no curl, no grip); runtimes with joints but no mesh get a skeleton; non-finite joints put only that hand back on its grip curl. AuroraCockpitHand carries the 26 seated-frame joints and radii. - The manifest declares horizonos.permission.HAND_TRACKING (and the deprecated com.oculus.permission.HAND_TRACKING), both normal permissions with no prompt on a Quest 3, and oculus.software.handtracking as optional; without it Horizon OS keeps the app controllers-only. Bare hands then drive khr/simple_controller, so on Android a hand whose squeeze action is inactive and select active is treated as bare: with the option off it presses nothing but the menu gesture, is not drawn and feeds no Wii Remote motion. - Interaction-profile changes and tracker sources are logged. The pure rules (grasp from finger flexion, bare latch, pinch gate, bare-hand buttons, flick) live in the OpenXR-free vr/openxr_hand_tracking.h with mkw_vr_hand_tracking_tests; the driving and flick parts are wired in the next commits.

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.
