OK, after just a little playaround with the actual title, it does seem that the frame rate is too low on this port. There appear to be animation frames missing in some places (very noticeable when jumping - looks a little too much like teleporting). The falling floor and ceiling tiles flicker just a tad before the fall and seem to have no heft to them. Also, the sound effects should have been ADPCM samples (this is a frikkin CD game) instead of PSG effects. I dunno. I really think this was just a half-assed port. There's nothing in PoP that the PCE couldn't do well and I'm disappointed that this port is so lackluster. It seems to be the worst of the home console ports, and that shouldn't be the case. It looks just a hair better than the Sega CD port (when not in motion), but the Sega CD version has the right sound effects and the game seems just a tad more solid, for lack of a better descriptor. Even though the Sega CD version seems just a hair shy on frames as well, they flow together a hair better.
