I got it to work.

I changed my BIOS name to all lowercase, changed the memory card name to all lowercase then booted through the BIOS on the SD card and it detected the memory card and is working perfectly now

I'm playing Dragonball GT Final Bout and when it says select memory card and I choose slot 1 it just says "save error" and it doesnt save

any idea how to fix this? I really want to be able to save
