Shin Megami Tensei: Persona 3 Portable

[Blueenk]

(I use cheats by the way)
I just defeated the boss in the train. Then there was shuffle time. I thought that it was really nice that I would get a new Persona just by getting the right card, but then it just froze. I can't do anything. The music is playing, and the flashy animation is there.

Is there any way to play my save file again? I have ES file explorer, and I tried editing the save data by deleting some of the characters, but it says that it can't play because it's for an older version of the emulator...

Or I could just play it again. I have a save file in the game, but it's really far away compared to where I am in the game now...
