- Human work and limitations
- The project uses a static recompiler to achieve cycle-for-cycle identical behavior to the original hardware. The author notes that while the recompiled code handles the bulk of execution, self-modifying code or missed disassembly segments fall back to the interpreter.

What was done
Project Arwing is a static recompiler for the SNES game Star Fox, converting 65816 and SuperFX instructions into C code to enable native execution with quality-of-life improvements like HD 3D rendering and smooth frame rates.
Project Arwing is a static recompilation project for the SNES game Star Fox. The README documents that the project utilizes a static recompiler, tools/recomp.py, which converts every 65816 and SuperFX instruction into C, avoiding an emulator loop for the majority of the game. The resulting C code is described as a mechanical translation rather than hand-decompiled code. The project provides a runtime environment that includes a PPU, SPC700, S-DSP, and SuperFX interpreter fallback, alongside a launcher supporting HD 3D, CRT filters, and controller input. The README notes that HD 3D recovers sub-pixel positions for approximately 85–90% of vertices, with the remaining projection routines in src/hd.c identified as a gap for future work. Recent development includes the implementation of a smooth 60 fps mode via frame interpolation, with several commits co-authored by Claude Opus 5.5. Users must provide their own Star Fox (USA) (Rev 2) ROM to build the project. Further details are available at the official repository.
