About

Mike Tyson's Punch-Out!! is a boxing game for the NES. This is a reverse-engineering effort to disassemble the NES game Mike Tyson's Punch-Out!!. The build script assembles the source files with the Ophis assembler and checksums the output against the original memory-bank images, which are expected to be identical. It is not a standalone playable game.

Getting started

Run the included build script from Git Bash to assemble the source and compare checksums; the author notes the script can be modified to produce a working ROM.

Requires original assets. Reverse engineering disassembly project requires original NES ROM to produce a working output.

Status & roadmap

A completion map in the documentation folder visually shows how much of the disassembly is done, and the author planned to post progress on nesdev.com.

Additional notes

Readme quirk: The README's build section mentions the Dragon Warrior NES ROM, apparently carried over from another disassembly project.
