What is cc65?

cc65 is a complete package, which includes

  • a C compiler for machines with a 6502-compatible CPU,
  • a powerful macro assembler,
  • a linker, a librarian, and several other tools,
  • target libraries that support common 6502 platforms like the Commodore C64, the Atari 8-bit machines, the Apple II, and others,
  • documentation and more.

Host platforms

According to the original author and former maintainer: "With one exception in the compiler [access()], the code is plain ISO C; so, it should compile on most systems. Memory usage may be a problem, however."

cc65 can surely be compiled and run on the following platforms, for which GNU Compiler Collection -- GCC -- is available.

Target platforms

  • Apple II
  • Atari 2600 and other Atari 8-bit machines
  • Commodore machines
  • GEOS
  • NEC PC-Engine (TurboGrafx-16) game console
  • Nintendo Entertainment System game console
  • Ohio Scientific Challenger 1P
  • Oric Atmos
  • Watara Supervision game console
