Hi i have a r4sdhc cartridge with 8gb micro sdhc card. I have put the firmware and games onto the card and it works perfectly if i put it into my friends r4sdhc cartridge it works prfectly , but when i put the little card in my nds it just says loading and then menu(has a little red logo of a sd card with menu printed underneath).Has anyone heard of this???What am i doing wrong. It cant be the formwire thats wrong if its working in another cartridge can it? Any one have any experience of these things?
