The codes I made in the database for this game are for the Sega Genesis. I made them with Kega Fusion years ago. There are three Inaudios codes there. Whenever you use Inaudios, it only lasts til you enter a town or cave. remember to cast it whenever you leave a town, enter a cave, or leave a cave. I haven't played any Genesis games on PS2, so I can't help you there. I suggest you correspond with Lee 4, who does a lotta good work on PS2 games.
