Similar to the Japanese version, the USA release of Pac-Land on PC-FX aimed to bring the classic Namco platformer to a home console audience. The core gameplay experience would have been the same, but potential alterations in controls, graphics, or even content could have been implemented to suit the North American market.  Further research into gaming reviews and historical documents from that period could shed more light on the specifics of this release.
