Updated to the native optimization engine, pinned at cf1680122fda0cc49c4e8774d9b065b5c8b768e6. Native RAM access, text rendering and presentation conversion reduce host overhead while the audited GBA BIOS continues to execute as generated LLE code. Generated guest code uses O2; Windows runtime code uses O3.
The matched 8x wide-race workload on the older Windows GTX760/OpenGL qualification host used 11.0% less process CPU time. Other measured workloads were neutral/inconclusive. This is a whole-package CPU result, not an FPS claim. Higher Internal Resolution and adaptive display choices remain available.
Native in-game saves are preserved. Save states are specific to each build. Supply your own supported ROM and GBA BIOS; neither is included.
