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??
