Hello guys, Im a new owner of a slim PSP and I just realized now that you can't immediately play iso and cso files on your PSP without installing custom firmwares. I have read in the tutorial section of a certain forum that in order to install a custom firmware to a Slim PSP with 3.60 version, you must need to install Pandora Battery. And in order to install a Pandora Battery, I need to have Access to a PSP that has custom firmware installed and an original PSP. Now, my probelm is that I don't have any of this. Do I still have a hope on playing ISO and CSO files on my slim PSP? If yes, can somebody please help me?
