Hi..friends hw can i play ISO/CSO downloaded games from memory stick..i have psp 2004 with 4.01 version software..plz help

after u download the game, u just copy the file to the "ISO FOLDER" in your memory stick.



- connect your usb data cable from PC to PSP
- IN PSP go to USB Connection and activate it
- your Memory Card should be shown in your PC as a removable drive
- now u can copy the game to ISO FOLDER in your psp
