    if you dont HAVE 3.71 M33-3 or other custom firmware
    you cant play downloaded cso or iso sry
    please downgrade psp to 1.50
    then upgrade to 3.71 M33-3 then you CAN play ISo's or CSo's

    for downgrade en update to custom firmware search forum !
    i did it to im on 3.71 M33-3

    ps.
    use the search bar on top of homepage!

    If you have org psp 3.71 YOU CANT PLAY ANY ISO so dont say it did?
    because if the people here read it they wont respond to it because it isnt possible.

    If you have custom firmware then download the cso over again they are bad.
    or try the forum there is a thread of it to rule out al prob. etc.
    or wrong folder on psp is it in ISO FOLDER ?
    GL :p

    If this is a PSP SLIM you can not downgrade it to 1.50 firmware. I wouldn't even downgrade it to 1.50 firmware even if it was a FAT PSP.

    You will need to use a Pandora Battery no matter if it is a FAT/SLIM so just install the Universal Unbricker V3 onto the Magic memory Stick which will install straight to 3.71 M33 custom firmware. This custom firmware will then play your CSO/ISO games.

    Do you have access to a PSP that has custom firmware on it? A friend or family member that can play ISO/CSO off their PSP?

    First off go to System Settings then System information and check to see what firmware you have listed under System Software.

    If there is no OE/SE/LE/M33/HX after the version number then you have probably updated the PSP to official firmware and will need to re-install a custom firmware to the PSP.

    If it has 1 of the above CFW labels after the firmware number then try the steps below.

    Go HERE and follow these steps to try getting them to play properly.
