ISOs working while CSOs don't on 3.03OE-A?

    I recently purchased a used PSP modded with 3.03OE-A firmware.

    While experimenting I have noticed that this version of firmware will load ISOs just fine but when I try to load a CSO I get:

    "The game could not be started (80020148)"

    Is this happening because OE-A cannot load CSOs?

    Also, I would like to "upgrade to 3.52 or 3.71 (from 3.03OE-A). I have searched the forum and come up short trying to find a guide to upgrade from OE-A. Is it worth upgrading? If so, can someone provide a like to do so.

    Thanks ...

    Yes it is worth updating.

    Go HERE to update to 3.52 M33-4

    Then go HERE to update to 3.71 M33-2 (you need to update to 3.52 M33-4 before updating to 3.71 M33-2).

    After you have updated to 3.71 M33-3 go HERE and download the 3.71 M33-3 update and drag the update folder to the /PSP/GAME folder and run it. You will now be at 3.71 M33-3.

    After your finished format your memory Stick so the newer directories are created.

    Then go HERE to get your ISO/CSO files working properly.
