I updated the System Software of my PSP slim to a 6.38 version. Whenever i look into the game>memory stick, it has no games in there. It always says, "There are no games", but when i connected my PSP to a computer (via USB cable), looked into ISO folder, the games are all there. So I tried formatting the memory stick. After formatting the memory stick, the ISO folder is gone. Can someone please help me?
