The PCE version actually seems to be expanded upon over the arcade version. I don't know if the Neo Geo CD version has as many modes, but if you choose RPG mode in the PCE version, you get to control your character and walk them around, but in the arcade you just watch the sprite go from point A to B. The cinematics may look bang on, but they're actually redone at a larger size (not just squished horizontally) and touched up as well as the arcade (perhaps better as it looks to have extra anti-aliasing). The first opponent's map sprite wasn't recolored on PCE because of color limitations, it was fixed to match the cinema art.
