Yes I'm sure the card is not the problem. I'll go over it from the top. I tried several codes for the 4 different versions of GT2. I found out that I have just regular GT2 no version number. I tried some engine switching, it worked. I wanted to save my new hybridized cars, it saved just fine, but before it saved, it told my my mem card was not formatted than it saved. So I checked out the cards by turning the ps on but leaving the lid open, it said there were GT Game files on them. I dunno what the deal is. I'm going to try again today b/c I was pretty groggy when this happened.
