Guys here are some recommendations for PSP
• You can install games on PSP in two ways.
• First and recommended way is to buy original UMDs and insert into your PSP and enjoy your game on PSP.
• The other way is to hack PSP by installing custom firmware on PSP, download games from the internet, put them into your PSP memory stick and then play games on PSP. The downloaded PSP games are in ISO/CSO format.
