Yes i know its old, but i use my M3 adapter CF for gba games. It worked fine but know im getting this error, 'Your CF card is not Formatted, shut down and put a Formatted CF card in the M3 adapter'. I never had this error before but i did what it said and formatted my card, and as you can guess i get the same error over and over again. I formatted a few times but it still won't work. Does someone know what i can do?
