[SexiestManAlive]

I have an old 3ds, does anybody else experience a freeze after finishing the second level in classic mode, its never done it before, it just started out of nowhere, i didn't change anything on the system or in the game, so i dont know what happening.

Corrupt savedata, corrupted game or corrupted SD.
