Tool z88dk dis - marinus-lab/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, z180, z80-z80n and Rabbit processors) as well as other related (but unsupported by z88dk) processors: R800, 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.
