Supposedly ... if there is nothing under the 120V it's 1.5, A=1.51, B=1.52 ... not sure though. My 1.5 PSP had nothing under the 120V. Might want to browse around some psp forums, I'm sure many others have asked the same question.
To play downloaded isos you just copy them to your Memory Stick Duo Pro(tm) via a usb cable. There is a program someone made called Fastloader that will load around 95% of the isos available.
