My kids are complaining that their DSi 'hangs' a lot while playing games. They've played for more than a year succesfully but the last weeks/months they complain more and more. Can it be that the Acekard is defective? I already tried formatting and starting clean. If I buy a Supercard DSTWO, can I pull the MicroSD (16GB) out of the Acekard, plug it in the DSTWO and all games will still work including savegames?
