When I hook my PSP to PS2 it does not recognize my PSP as flash drive. My PS2 is v7 and scph39001. I read that I can snap shot some games like GT$4 to psp. I also bought GameShark with Media Player and there is an option to see the drive hooked up to ps2 but PSP is not recognized. I don't have slim version of PS2 but I am pretty sure mine is compatible. The PS2 should recognize flash drive. Do you have any idea why?
