Tool z88dk dis - z88dk/z88dk GitHub Wiki

A full z80 disassembler is provided with z88dk. In addition to supporting the z80, it can also disassemble code for the other supported CPUs (8080, 8085 gbz80, ez80 (z80 mode), z180, R800, z80-z80n and Rabbit processors) as well as the related (but unsupported by the compilers) processors: ez80 (ADL mode).

Usage

At its simplest:

z88dk-dis -o [address] [binary file]

Will load binary file at the specified address and start disassembling from that point.

The diassembler understands the .map files generated by z80asm, and these will be read using the -x option:

z88dk-dis -o [address] -x [map file] [binary file]

Symbols that appear in more than one compiled source code file (module) will have the module name appended to them. e.g. a symbol named loop in modules fopen_c and fclose_c will become loop_fopen_c and loop_fclose_c.

Specifying the CPU

The following options control which CPU z88dk-dis will interpret the binary as.
