Millfork

A middle-level programming language targeting 6502-based, 8080-based and Z80-based microcomputers.

For binary releases, see: https://github.com/KarolS/millfork/releases (latest: 0.3.0, only for 6502)

Features

• high performance, due to being designed and optimized for 8-bit microprocessors

• multiple targets:

  • Commodore 64 (the primary target)

  • Commodore 64 with SuperCPU (experimental, incomplete and very buggy)

  • other Commodore computers: C16, Plus/4, C128, PET, VIC-20 (stock or with RAM extensions)

  • Famicom/NES (the second most important target)

  • Atari 8-bit computers

  • BBC Micro

  • Apple II+/IIe/Enhanced IIe

  • ZX Spectrum 48k

  • NEC PC-88

  • Amstrad CPC

  • CP/M

  • Atari 2600 (experimental)

• inline assembly

• simple macros

• pay only for what you use: not a single byte of memory is used unless for code or explicitly declared variables

• simple memory model that avoids using the stack

• multi-pass whole-program optimizer (that will even optimize your hand-written assembly if you ask it to)

Licensing

The compiler is distributed under GPLv3 (see LICENSE).

The standard include files (located in the include directory) are distributed under a more permissive Zlib license (see include/LICENSE). Therefore, no attribution is needed if you are developing and distributing Millfork programs.
