Snes SDK Toolchain

Yesterday i learnt from Lint that there is a new Snes toolchain coming down. 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
