I have a problem. I have 2 games on my Memory Stick Duo. But they don't appear when I put the Memory Stick in my new PSP. When I put the Memory Stick on my old PSP, they will appear. Do you have a solution for that?

Hey Thierno, it's because the games won't appear unless your signed into the PSN account they we're purchased from on that psp. Another issue would be if you had custom firmware on your old psp, that the new psp doesn't have the same custom firmware as the one on the memory stick

Call game stop I have no idea about psp

My PSP won't accept the Wi-Fi I got so it would be harder for me to sign into PSN or download the same custom firmware.
