My micro SD recently crapped out on me, but I was surprised to find that by running the 3-in-1 by itself it contained the save file I had been using. I'm wondering, where is the save file located? Is a backup made on the 3-in-1 or something? Is there any way to extract it from the 3-in-1? I'm afraid to switch games, for fear that it might delete my save data.
