I have Final Fantasy Legend 2 on my DSTwo (cart works on newest 3DS firmware), and have run into what might be a glitch in the ROM. Using an item causes my save to be deleted from the game's point of view (a .sav file still exists on the SD card, the game doesn't see it). Has anyone else hit this type of glitch (I can describe the location/item that triggered it) or knows how to get the save back?
