I reformatted the card, I am pretty sure I used another card after. But I can try again with a fresh card. Would having so many games on there be an issue too? There still is lots of room for save files thoughIs it possible that the MicroSD is corrupted?
That doesn't tell us much. There are about a million different R4 clones with similar names.I have the 3DS RTS. Not the B9S compatible one though. It seems to work fine when the micro sd only has a few roms on it. So I might try using 2 16GB cards instead. Maybe its a bad rom thats screwing up the bunch.
