Z88DK is a C cross compiler package that targets the z80 and consists of a C compiler, an extensive set of assembly language libraries, an assembler / linker, and a tool for generating executables in a number of formats. Development in C, assembly language or a mixture of the two is directly supported.

More than 40 specific targets have ready CRTs in the package. This includes a CRT for embedded systems which allows the generation of standalone and ROMable software out of the box.

The current release allows SDCC to be used as alternate C compiler, giving it access to some of z88dk's CRTs and its more complete z80 library. Executables generated by SDCC in combination with z88dk are both faster and smaller than native SDCC builds. The CRTs allow SDCC compilation to be done without having to do any setup. The z88dk library completes C standards compliance for SDCC.
