- Introduced a new GX thread to handle the rendering pipeline, allowing the game thread to post commands without blocking. - Added `gx_thread.h` and `gx_thread.cpp` to manage the command ring buffer and thread synchronization. - Updated `vi.cpp` to utilize the GX thread for rendering tasks, improving frame pacing and responsiveness. - Modified `main.cpp` to configure and start the GX thread, ensuring it integrates with the existing rendering workflow. - Enhanced `openxr_integration.cpp` to register the GX thread with OpenXR for better performance in VR scenarios. - Refactored `settings_overlay.cpp` to remove unnecessary waits for the frame worker, as the overlay now draws directly into the game thread's ImGui frame. - Improved error handling and logging in the GX thread to capture exceptions during command execution.
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.

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.
