I have a super card mini sd, a 1 gb mini sd card, a device to connect the mini sd card to the computer, and a gameboy advance sp. I put a .gbm and .gbs to the mini sd card and in the super card but when I turn on the gameboy advance sp I look at the list and there is nothing on the list. What am I doing wrong? Can I play videos using a supercard mini sd? If so how?
