Every single time I try to copy data from another memory card to this one, the data is corrupted. This is mainly for Super Smash Bros Melee. I've tried formatting it before but it continues to happen. I've been using a third party memory card since I've had my Gamecube in early 2002. I felt it was time for an upgrade due to small size and the fact that apparently third party memory cards corrupt over time. Yet it's my OFFICIAL NINTENDO memory card that isn't reliable at all. Anyone know the deal is?
