The Midway games are good but I agree, the controls are not the same
One cool feature, I believe that collection has it, is GAmeShare where wyou can download a game to your friend's PSP and they can ply it until they shut it off. Also, it is not MAME. They actually had to rewrite emulators due to the amount of user cod in the MAME source. The problem is they can't tell if someone submitted some component that has copywritten source code. So rather than face legal action they just rewrite the emulators they need.
