- 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.

Aurora is a source-level GameCube & Wii compatibility layer intended for use with game decompilation projects.
Originally developed for use in Metaforce, a Metroid Prime reverse engineering project. It now powers several completed source ports, including Dusklight.
Features
- Application layer using SDL3
- Runs on Windows, Linux, macOS, iOS, tvOS, Android
- GX compatibility layer
- Graphics API support: D3D12, Vulkan, Metal
- Highly accurate and performant GX implementation
- Robust pipeline cache system with "transferable" cache support for releases
- Dolphin-compatible texture pack support
- Widescreen & resolution scaling support
- Custom APIs for offscreen rendering
- PAD compatibility layer
- Utilizes
SDL_Gamepadfor wide controller support, including GameCube controller adapters - Automatically saves and loads controller bindings and port mappings
- Gyro & mouse support
- Utilizes
- DVD compatibility layer
- Utilizes nod to support all GameCube/Wii disc image types, including RVZ
- CARD compatibility layer
- Full compatibility with Dolphin
.gciand.rawfor game saves
- Full compatibility with Dolphin
- Dear ImGui built-in for simple debug UIs
Graphics
The GX compatibility layer is built on top of WebGPU, a cross-platform graphics API abstraction layer. WebGPU allows targeting all major platforms simultaneously with minimal overhead. The WebGPU implementation used is Chromium's Dawn.
Building
See docs/building.md for build instructions, CMake integration, and configuration options.
