I swear I've looked everywhere else I can think of, but I haven't seen this addressed. I recently put a few GBA games on my DS. I have yet to try all of them, but when it comes to saving my games, three out of the five that I've tried work perfectly. Two however (obviously the two I wanted to play most) won't save correctly (Metroid Fusion and Metroid Zero Mission). I can save my game, but when I reload it I get a "Data is Corrupted; Deleting File" message. I've heard of saving problems, but nothing intermittent like this. I've read that inserting a particular hexcode into the save file would fix some stuff, but the hexcode in question was already there when I checked. So... I'm not sure what to do to fix it... Anyone else had stuff like this happen?
