There's been problems with doing this translation. It requires adding more dialogue boxes than is necessary, and this kills any type of compatibility with original replays, since it makes it go out of sync. Also, the cutins for the spellcards and such are in compressed dat files, which haven't been decoded yet. The dialogue boxes will probably need to be altered; either that or people will have to deal with the incompatibility of replays (there might also be other problems).
I was looking into hacking this game before but gave up for awhile. I might try again in the future when I have some time.
Have you been able to fix any of these problems though?
