Contra US Annotated Disassembly

Source Code


This zip contains an annotated disassembly of the Contra (US) NES ROM and the build script(s) to reassemble into a byte-for-byte match of the game. The zip also contains supplemental documentation, diagrams, scripts, and tools to further understand the game.

A special thanks goes to Trax. This project would not have gotten started without the amazing initial disassembly by him for his Revenge of the Red Falcon project.

It is a zip of the v1 files from taken on 2023-04-26.
