I also got that Demo in the mail, but I let my neighbor with a v2.60 PSP borrow it from me. I read on PSP Updates that some guy got the UK version of the real game working, though...don't know how true that might be, but I just thought I'd let you know...I'm gonna try the demo out in the weekend to see if it runs....It's a shame about Street Fighter Alpha 3, I've had it since it came out, and still haven't been able to play it. Even the ISO I dumped from my legal copy fails to run on every loader out there.
