Hi, I have a NDS/GBA Flashcart (It was for the original DS) And it acctully works on my gameboy micro, although might stick out a little bit. Anyway, I can't seem to get any of the GBA games to save. Somehow, only one did, Metroid: Zero Mission, the first game I played on the cart. It bothers me because I want to play games like Pokemon, Super Mario advance, and some other odd titles. It dose say im missing some file (Called *.Dat) but I can't seem to figure out what it is. I do infact have Goomba, So the GBA games and GB games work. Just not save. Please help? Thanks.
