Apologies in advance, I tried to explain how everything works as succinctly as possible but there are a lot of steps involved. Here is the toolkit that was used for the PMD WiiWare fan translation.
Tools included are 3 by me:
PMD WiiWare Text Editor for Cool Kids (a text editor with script comparison with original English script)
Footprint Runes (Font Editor)
Basement Floor (Dungeon Titlecard Font Editor)
And 2 by other members of the team:
at7comp.py, a Python 3 script to be used for compression
Conversion Toolkit (For texture conversion and filesystem management. It has a compression routine but it's slower, so the Python one is preferred.)
Also included are image files and a vector file for making your own logo.
