I don't think the arcade version had any paralax in any of the levels IIRC, so, I don't totally take that into account on which one is more arcade accurate. But, still, it would've been nice is the PCE version had paralax, & it would've been nicer if the cd version had redbook audio! Not to mention 2 player support. Why doesn't the cd version support 2 players anyways? Anyone know??
