Hi, I recently ordered a PSP [it hasn't got here yet, so maybe a better time to ask questions about it would be when it gets here?^^; I dunno, I wanna be prepared ahead of time..], anyways, I was doing research online on how to do the custom firmware to make PSP's play ISO's/CSO's, and I found a few nice tutorials. The PSP I ordered, I know it said on Ebay, is a v1.5, and I was wondering, is it necessary to upgrade it to the v3.52 M33 in order to make it play the ISO and CSO games? Or does v1.5 automatically play those? I'm just not clear on that part, and I don't want to mess something up before I go ahead and upgrade the firmware >< Thanks in advance!
