    you can't do emulators or iso/cso games on official 3.71. you need custom firmware 3.71 m33-3 to do all that.

    and the only way to get custom firmware on psp slims is with pandora's battery and universal unbricker v3 memory stick. no other way.

    You have 3.71 M33 or 3.71 official?

    If you have 3.71 M33 (Which i figure you do since Emulators work) go HERE and follow the steps to get your ISO/CSO playing properly.

    If you have 3.71 Official Firmware then you need to install custom firmware 3.71 M33.

    Thanks for the help larrylje, got it working now.

    I did have the custom firmware on my psp just forgot to add that, glad someone noticed that I was able to play the emulators but just not the games.

    Cheers again.
