To elaborate, this is what the text data looks like--just a bunch of BG numbers. One could decode which kana represents which number by viewing the BG map, but it's gonna take forever since there are thousands of lines - can't do this myself. If you or the group can dump this in a PC and decode the data to normal Japanese text, things would be MUCH easier. Dunno if it's doable but that's that.
