fyi ps2's played ps1 games as well and the ps1 controllers and memory cards were also compatible with the system so you might want to make sure, there is a big difference between the two and if it happens to be a ps1 card it will not save ps2 data only ps1 data...I know that I would be pretty sad if it was the wrong thing. does it have any markings on it anywhere brand name model number ect? just trying to help. good luck
