Z88DK is a complete cross-development kit for the Z80 family of processors (8080, Z80, Z180, ez80, Rabbit, GBZ80 and more), providing C compilers, an assembler, linker, and extensive assembler-written C libraries. It supports over one hundred target machines out of the box, producing runnable artifacts like tapes, disks, and ROMs with a single zcc command.

Use cases

  • write C programs for ZX Spectrum and other retro computers
  • cross-compile C to z80 embedded targets
  • assemble z80 assembly language projects
  • build ROM images or .TAP files for emulators
  • develop software for 8080 or Rabbit 2000/3000/4000/5000 CPUs
  • mix C and assembly in one z80 project
  • create games for classic z80 machines

When to choose

  • targeting any of the 100+ supported z80-family machines
  • you want an optimized C standard library written in assembler for z80
  • you need a one-command build producing emulator-ready artifacts
  • you want to mix C and assembly freely

When to avoid

  • targeting modern CPUs like x86 or ARM
  • you need a hosted POSIX C environment rather than embedded/retro targets
  • you require a fully permissive open-source license (license is non-standard)
