odd, Just tried Kirby as I hadn't before, works just fine for me (haven't played much, but loaded pretty fast and managed to actually play the first level.So most of what I've tried has worked fine, but 3 games have given problems. Puyo Puyo Tetris won't show up at all no matter what I rename it to, trimmed or not. And Kirby and Penny Punching princess both just give "the game card could not be read" errors. Tried files from multiple locations so it's not the files at fault. And I'm on the latest OFW version, with an ExFat formatted Micro SD.
Looks like some games like error that occur no matter what (i.e. 1-2 switch freeze when playing eating game or DK freeze having slow loading times but working), and some could be due to either the sd, the formatting, or some other reason.
Ps all, I will be away today at a photoshoot so won't get much time to see posts, so if some important information get's shared, please PM me so i can add it to the front page!
