I got to about 30% in this game and all the sudden it said the data was corrupt. I started all over again and soon as I got to about 20% same thing. I have tried different memory cards and same thing happened. The were 2 seperate profiles on the cards. You can save three profiles on one save I guess. Anyways anyone had similar problems with this game or in general? it is a ps2 mem card not aftermarket. Seems to work fine with all other games If this is a general memory card question maybe someone can tell me the best place to post about it. Anything? Just someone please help. This is an awesome game but losing your progress is very frustrating Thanks in advance...

There is a similar memory card issue with Soul Calibur 3, although this sounds like it could be a problem with the game or maybe a bug in these early versions. If it's still under warranty (and even if it's not), I'd try contacting EA Customer Service about this, since it could be a defect with the game.
As for general questions, you may want to try the General PS2 Forum.
