cmpdism is a “comparative disassembler” targeting multiple CPU architectures. Its chief advantage over other disassemblers is that it is specially designed to be able to compare the disassembled code of different revisions of a program and output the differences, accounting for possible differences in addresses and constants between the revisions. This makes it useful for comparing prototype and final versions of a program, or finding differences between different regional releases.

Currently, the following architectures are supported:

• 6502 family:

• MOS Technologies 6502
• WDC 65C02
• Hudson HuC6280

• 68000 family:

• Motorola 68000

• SH family:

• Hitachi SH-2

• Z80 family:

• Zilog Z80
• Sharp LR35902

• Multi-processor instruction sets:

• MIPS-I (coprocessor instructions currently unsupported)

This program prints to stdout and you can pipe the output to a TXT file by adding filename.txt to the end of the command.

Source code and future updates available on GitHub. This is a bog-standard C program with no external dependencies, so you should be able to compile it on anything without too much trouble. This specific upload is a Windows build.
