- The pacing thread aims each immersive window eye through the window itself (AimEyesThroughWindow): it keeps its position but looks square-on at the window's plane through an off-axis frustum just around it, so the eye image is the window, at the display's pixel density (about 680x380 per eye at render_scale 0.8 instead of 1344x1408), with a two-pixel border the mask leaves transparent. The frame's views carry that pose and field of view to the projection layer. - vulkan_interop.cpp copies an eye smaller than its AHardwareBuffer into the buffer's corner, and the Quest layer's imageRect is the rendered part of the swapchain image. - These eyes are not foveated: their field of view follows the head, which would rebuild the density map every frame. - Quest only (kWindowShapedEyesSupported); the PC backends copy whole eyes and keep masking them. debug.wiicompiled.window_eyes 0 renders them whole and masked again for A/B timing. - Quest 3, paused Retro Rewind race, render_scale 1.0: Immersive window runs the GPU at level 1 (456 MHz, app GPU 11.0 ms, eyes 8.4 ms) where Immersive needs level 3 (599-640 MHz, 13.4 ms, 10.3 ms), about 42% fewer GPU cycles. No edge artifacts, image as sharp. Docs: OPENXR.md. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
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.
