I'm having trouble with this game. I back the original game up to my HDD via DVD2XBOX. It boots up fine but when I choose Arcade mode it gives me an error "this game must be played from the original disc" or something like that. So I turn off/on my xbox and I got past that. When I play against the computer, I can't do any damage to him, and it only takes one hit from him to kill me. I patch it with Craxtion also and no luck. Anyone?
