Build Status

cc65 is a complete cross development package for 65(C)02 systems, including a powerful macro assembler, a C compiler, linker, librarian and several other tools.

cc65 has C and runtime library support for many of the old 6502 machines, including

  • the following Commodore machines:
    • VIC20
    • C16/C116 and Plus/4
    • C64
    • C128
    • CBM 510 (aka P500)
    • the 600/700 family
    • newer PET machines (not 2001).
  • the Apple ][+ and successors.
  • the Atari 8-bit machines.
  • the Atari 2600 console.
  • the Atari 5200 console.
  • GEOS for the C64, C128 and Apple //e.
  • the Bit Corporation Gamate console.
  • the NEC PC-Engine (aka TurboGrafx-16) console.
  • the Nintendo Entertainment System (NES) console.
  • the Watara Supervision console.
  • the VTech Creativision console.
  • the Oric Atmos.
  • the Oric Telestrat.
  • the Lynx console.
  • the Ohio Scientific Challenger 1P.
  • the Commander X16.

The libraries are fairly portable, so creating a version for other 6502s shouldn't be too much work.
