Hello lads. I'm having a huge problem with my DSTT. I was half way through playing a game when all of a sudden the entire thing locked up. The music was still playing and animations were still playing but I couldn't move nor do anything, nothing would work. I turned off, then turned back on again, and now the DSTT won't get past the 'Loading' message BEFORE the menu. I can't get into the DSTT menu at all. I have tried normal DS cartridges and my friend's DSTT and they work fine. The MicroSD card is fine, my PC reads it perfectly. I reformatted in FAT, same problem. FAT32, same problem. With games, without games, with menu, without menu, all locking up at exactly the same point. It seems to be picking up that there's a card there then just locking up, regardless of what's actually on the card. Friend's MicroSD in my DSTT, same freeze as with my own MicroSD. Without a card, it does recognise this and comes up with the NO CARD?? error. Does anybody have any advice on what to try before I go for an RMA?
