I purchased a DS Firelink card while I was in China, it worked just fine until I tried opening up a program called "N-Card" or something like that. It reformatted my fire card and now whenever I turn it on it shows the N-Card menu and not the usual firecard menu. And also when i try to hook it up to the usb link using the N-Card menu it doesn't work because it says the disc needs to be formatted. How do I format the disc, or better yet how do I erase the N-Card stuff and turn it back into a dsfirelink card?
