This is a comparison page for the PC-Engine CD-ROM and Genesis versions of ValisIII. Gens was used for the Genesis shots and Magic Engine was used for the PC-Engine shots. While the game's share similarities in gameplay and specific parts of levels, they are basically two different games, with the PC-Engine title being much longer, and more detailed in storyline and level design. The Genesis game has more parallax though.

These shots follow the order in which they occur on the PC-Engine version, the Genesis shots are intermixed whenever the shot occured on the Genesis. Only certain stills in all of the cutscenes were cut out of the Genesis translation, but level similarities don't go past the first level.
