Well my pre-hacked psp came today. And I know absolutely nothing about it, i just REALLY want to play yugioh tag force 4, and i copied the iso onto the mem stick, and it said it couldn't play. I got this error code. 80020148 Now, I googled and got multiple solutions, most of which I didn't know how to do or didn't quite understand. One said i needed a PSAR file, and other said i needed to into the recovery mode and disable things, but i didn't understand what it said to disable... I have 5.50 Gen-A and it's a PSP SLIM Sorry if there is a solution in one of the stickies, but I just don't see it in there.
