My brother is having a serious problem with his PS1 memory card. Basically, whenever he saves a game on his memory card on a PS2, it acts like it saves fine, but when he tries to load it, the data isn't there anymore. He can't save on our PS1 either because the PS1 doesn't allow him to reformat his memory card (he's done it once before, but it doesn't work anymore). Anyone have any ideas as to what the problem is?
