I just bought a Supercard DSTWO for my DSi XL and I everything I was told to do in the beginner's guide and got the latest kernel and patch and the latest gba emulator too. Now the problem I am having is some times when i put in a DS rom (example: Legend of Zelda Spirit Tracks - Patched) and try to run the flashcard but nothing comes up and when i plug the SD card back into my PC to take the rom off, it tells me to do a reformat. Is that a serious problem or am I doing something wrong? It seems to be okay now but does it mess up when games are patched? or something else?
