Don't ask me how, but I managed to corrupt my Gamecube memory card using GCMM. When I boot it up with the memory card plugged in, if I try to copy a save to it, it will say file/dir error. If I take it out and plug it back in, or boot it without it in and plug it in afterward, I can copy saves to and from it. However, if I copy Animal Crossing's save file, it will say that there's not enough space on the card. There was enough space before it corrupted, which leads me to believe that GCMM didn't delete a save file correctly. No matter, even when I manage to copy a save file onto the card, the corresponding game I play will give an error such as "The memory card in Slot A is corrupted." or "The memory card in Slot A must be formatted", so it doesn't really matter that I found a way to copy saves to and from. I thought no biggie, I'll just reformat it with the Wii system menu, but it seems that the Wii system menu has no such feature. Instead, it says "The device inserted in Slot A cannot be used." Darn. :/ I understand that the Gamecube can format corrupted memory cards, but I don't own one and none of my friends do, either. One option is that I could probably send the memory card to my sister in Arizona who does have a Gamecube, but I want to do that as a last resort. Is there anything I can do with the Wii, such as a homebrew program, should I send it to my sister, or should I not even bother with it and buy another card online? Thanks!
