hey you're not so far in, just to let you know. From my experiences with that game, you just have to start over or back up your saves. Lemme guess, you used codes or cheats and your game corrupted? Don't worry it happened to me. I got so fed up with the game, i kinda stopped. I posted a topic somewhere on the NDS Emulation section of the forum so if you wanna look at what i got in return knock yourself out. All i know are completed saves on gamefaqs
