Hi there. I'm new here. Looks like a nice forum! Anyway, I plan on purchasing a PSP very soon. I plan on playing ISOs too via a 1GB Sony card. I wonder what version of PSP can play it that way? I've heard that only certain versions can do it, but I can't remember which. The PSP I'll buy is a recent one; definitely not 1.5, and is probably 3.0 or more. And is it as simple as drag n drop to card, then launch on PSP? Quoting a user's review here: Is that firmware update available online? and could I upgrade to it from ANY version? Take in consideration it will probably not be the US version. I'll buy it from Dubai, Midde East. Thank you...!
