Yes you can transfer data. *Just open the lid of the PSone and let the screen load. *You will then see Memory Card. *Hit X on it then goto Copy. *You must have your card in slot one and the other one in slot 2 before you do this. *Then copy it and you have a brand new save on the memory card.
-You may of had this difficulty if your memory card was not Sony made. *These 3rd party cards dont last very long and have problems like reading and writing information.
-Hope this helps. :thumbsup:
