legacy-puyo-tools 2025.10.10.1

A tool to edit text for older Puyo Puyo games.

Legacy Puyo Tools

A command line tool for modding older Puyo Puyo games (Yes, the name is using a reversed naming scheme).

This project is still in development, expect major breaking changes over its lifetime.

Why

Puyo Text Editor, fntedit, and other tools already can modify formats used by older Puyo Puyo games. However, there are advantages to rewrite them in Python:

• Better cross compatibility with Linux.
• Easier migration when upgrade away from end of life language versions.
• Formats are stored in an intermediate representation before conversion.

This project also aims to document how these formats work, so others can reimplement them if needed.

Progress Report

Current progress on implementing conversion and creation support for formats that are used by the older Puyo Puyo games. Includes regression testing and documentation. Additional formats may be added if there is a need to modify other Puyo Puyo games.
