So last night I was playing the new Harvest Moon ROM that just came out just fine, saved the game, waiting until it said "save completed", of course, turned it off, and turned in for the night. This morning, I came home from a trig class, open up my DS and see the "Menu?" prompt. Sure enough, I plug in my Micro SD and see that it's completely empty. No corrupted files, nothing out of the ordinary, just empty, as if someone formatted it. No one erased it or anything, no one in my house would. WTF happened? I haven't backed up my saves in a long time, and this sucks.
