I might have to hook up my psp to my ps3 and try it. They have to be somewhere on the memory card that is where it is stored. If you don't have a pro duo card reader you can buy one pretty cheap at microcenter. It is on bethel road... but still you should just plug in the usb wire to the psp, hook it up to a computer, and turn on the option to mount the usb device. Then you can see all the data on the memory stick
