Hacking changing language in dbz sparking meteor?

[syn13]

hi, i have been looking at some of my games with the trucha signer and was wondering if it was possible to change the language?

when i opened the iso in trucha, i saw some language files. the dir files seem to be for europe, usa, japan and korea but there are also arc files for 6 european languages. i wanna know what files i need to edit in order to change the text (not sound and music) from japanese to english? thanks for reading, any help would be greatly appreciated.

here's a screenshot if it helps:
