Final Fantasy IV Disassembly

About

Final Fantasy IV is a Super Famicom role-playing game that was released in North America as 'Final Fantasy II' for the SNES. This is a disassembly of Final Fantasy IV for the Super Famicom (released in the US as Final Fantasy II for the SNES), supporting both Japanese and English ROM versions (1.0 and 1.1). Building requires GNU Make, cc65 and Node.js, and the user must supply their own unmodified ROM to extract game data from before assembling a matching ROM; the Japanese 'Easy Version' of FF4 is not currently supported.

Getting started

To use it, install GNU Make, cc65 and Node.js, supply your own copy of an FF4 ROM to extract game data from, then run the build process to reassemble a matching ROM. The project also includes a step-by-step tutorial for making simple data edits, such as restoring a Japanese-exclusive battle ability that was cut from the English release.

Licensing & legal

• To avoid distributing copyrighted material, the project extracts all game data from the user's own ROM rather than including original assets in the repository, and recommends distributing ROM hacks as forks or via patch formats that don't leak copyrighted data.
