Yeah, I popped in Crash 1 & there's a slight lag. When you press jump, he jumps right after that. I hope there's someway they can fix that lag. Otherwise, it's really cool. They're working on up to being able to play PS2 & PS3 games as well on the PSP. The thing I wish Sony would do(& hopefully someone will do) is allow you to rip your games onto the hd, but, Sony will probably never do that, because people could bring a game over to a friends house, & let them rip it. I don't think there's anyway they could add one of those drm's or something to it(which I normally curse).
