I got this thing around a year ago, and it's been working fine;one of the best investments I've made. However, about a month ago none of my saves were loading, and then when I went to play a game, it wouldn't save at all. As in, many games require creating a save file before the game even begins, so I have just been stuck with a "Unable to save file -- please restart system" kind of message on every game I try. I've tried switching SD cards; no luck on that either. It's the same with GBA games. I know Perfects are outdated, so not everyone will have an answer... though help would be such greatly appreciated!
