hmmm...i can't seem to find the ruten table file...oddly enough, this topic appears near the top of google. could you maybe upload the tables you used? i tried making my own by bumping all the numbers up by the differnce of one kanji word, but it didn't quite work out. i did notice that the kana is all the same, though.
i didn't spend too much time on the rom, yet, but with what you're saying, my interest is now piqued.
could you please send me the table files you used, and i'll see if i can figure out how to work the text out.
oh yeah, the dialogue script and everything is int he evtdat.bin. the system.bin just has all the items and skill descriptions (a guess. i don't know japanese, but generally MANA+10 is not in plot related dialogue)
i'm fairly certain the script itself has all the string length and textbox stuff mixed in there, but i really can't tell for sure until i can see all the kanji...'cuz now i just have awkward spaces surrounding the kana...
oh, and if you want to do some screwing around with corruption, the first text of the game is at 1D4F0 of evtdat.bin. it's mixed in with the rest of the stuff, and but the first words of the game are, i think (from my somewhat limited jap knowledge) so-re-wa.
