How to run ISO/CSO games in PSP

How to run ISO/CSO games in PSP

IMPORTANT: Only works in FAT PSP with CUSTOM FIRMWARE, any version. If you don't have a CFW, you can make one here. If you have the OFFICIAL FIRMWARE 5.03 or PSP 3000, sorry guys, still NO HACKS for that.

DISCLAIMER: Do at your own risk. I do not hold any obligation if you bricked your PSP throughout the process. I tried this already and it worked without bricking my PSP. I think this process has 0 probability of bricking your PSP.

1. Connect your PSP through USB to your computer.
2. Download your ISO/CSO game. Enable USB mode in your PSP and make a new folder named "ISO" (all CAPS) in the root of your PSP, that is beside your PSP, MUSIC, VIDEO, PICTURE folders.
3. Transfer your ISO/CSO game in the "ISO folder".
4. Disable the USB mode of your PSP and turn it off. Remove the battery and replace it again.
5. Hold the RIGHT trigger as you slide the power ON button. A screen with black background and small red and white letters will appear. Sometimes, it takes me 3 times to make this work.
6. Go to Configuration, press X.
7. Make the GAME FOLDER HOMEBREW to CURRENTLY IN: 1.50 Kernel by pressing X.
8. Then select BACK and EXIT.
9. Turn ON your PSP and press the SELECT Button. Make the UMD ISO MODE to SONY NP9660 by pressing the right arrow button in your PSP. Then press X in EXIT.
10. Go to GameĆ  Memory Stick. And there's your ISO/CSO game. Press X and you'll be able to play it.

  1. i have updated my PSP 1001 to 5.03 now all my games ISO/CSO stopped working can u help

  2. 5.03 is an OFficial firmware. if previously you have a custom firmware then you updated your psp with ofw 5.03 then you can no longer use your psp to run homebrews and iso/cso games. so the best way to do is HACK it again using the pandora battery. You can find a tutorial here (just copy paste the address):

    check your version first by going to system settings. you should have your psp version there and you can confirm that ofw ver doesnt have M-33 in it.

  3. I was wondering if you could review my PSP Cso page and tell me if i have got it rite

  4. Will give this a try and will let you know how it went
