Yeah, It's an XDelta Patch. I don't understand what you mean by that, though. I normally just use IPS patches for my hacks, but I only use the GBA FE's so it's probably very different.
I tried putting those three in their own file, but then it cannot locate the XDelta file outside the file.
Seems like this is a problem unique to me. I wish there was a way I could help in producing a patch... If there was a pure Japanese text dump I could translate it in 1-2 weeks tops. Of course the culture localization would be WAY off, but wouldn't it at least be a start?
