My wii hates my GC mem cards. I have 2 GC mem cards. 1 which I've used for years but recently corrupted after it crashed whilst saving. This memory card isn't recognized by the wii anymore. (I get a message saying the inserted device isn't a gc mem card). And the second has ever since i bought it appeared to work but any saves it makes are corrupt.
So how do I format/ fix these GC mem cards on my wii?
