So, I've read that the Phat-sized 3in1 can be used in regular GBA's aside from a NDS. Since that one should, why shouldn't the lite-sized one work? Since it can't fit in a GBA (for obvious reasons) I've put it in my Gameshark SP. However, the GBA doesn't seem to detect it. I made sure to flash a game to NOR first, but it doesn't work. Is it just some incompatibility between Gameshark SP and EZ3in1, or the lite version was made to be incompatible with GBA?
