tja2fumen

tja2fumen is a tool for Taiko no Tatsujin games that allows you to convert TJA files (.tja) to fumen files (.bin).

This project attempts to replace/complement the existing closed-source tja2bin.exe converter packaged alongside TakoTako.

Goals

Act as a drop-in replacement for tja2bin.exe in TakoTako.
Fix https://github.com/Fluto/TakoTako/issues/16. (The original tjabin.exe doesn't properly handle #BPMCHANGE commands.)
Provide open source code to act as a reference for parsing and writing both the TJA and Fumen file formats.
Stick to the Python stdlib, i.e. no external dependencies if possible.

Usage

Option 1: Standalone Python installation

If you're familiar with Python, you can install tja2fumen by running:

pip install tja2fumen

Then, you can convert a TJA file by running:

tja2fumen file.tja

Option 2: Using with TakoTako

Note

: Before adding tja2fumen to TakoTako, you may want to back up the original tja2bin.exe file, to make sure you can switch back to the old converter if necessary. The easiest way to do this is by renaming the existing file to tja2bin.exe.bak.

To use this converter with TakoTako, head to the Releases page, and download the tja2fumen.exe file attached to the release. Then, rename tja2fumen.exe to tja2bin.exe, and place the file in the TakoTako plugin folder.

TakoTako's plugin folder is inside of the BepInEx folder, which will typically look something like:

C:\XboxGames\T Tablet\Content\BepInEx\plugins\com.fluto.takotako

Attribution

The fumen-parsing code in this project is based off of a modified copy of the readFumen() function from the fumen2osu.py found in @KatieFrogs' fumen-tools project.
The TJA-parsing code in this project is a Python translation of the parseTJA.js file from @WHMHammer's tja-tools.
