I have a NDSL, M3 mini-sd, passcard3, and a Transcend 2GB 80x minisd. DS games work great, the problem I'm having is when I try to load a GBA rom it hangs when loading. It will say loading and 0000 kb, but the numbers never progress and load. This is with FAT. I read on these forums to try FAT32, but when I format the card to FAT32 the M3 menu will not load and show up after the splash screen in both DS and GBA mode. Can anybody help me? I really want to play some GBA games.
