The Project can be found herehttp://code.google.com/p/snes-sdk/. Right now i have it running under linux. Just working on a patch for os x. Thumbs up to Ulrich Hecht for his work on this project.

Features:

  • WLA DX Assembler Backend
  • 816-tcc C Compiler
  • 816-opt ASM Source Code optimizer
  • crt0_snes Startup code in asm
  • libc.asm Tiny libc in asm
