It is indeed the NES version of Maze of Galious. Map is different, game is shorter. Would be nice to place that game in the engine of Maze of Galious akin to the Castlevania patch for Vampire Killer. Or the other way around: as inspiration to make an msx 2 version of Maze of Galious with more colors and multicolored sprites.
@JohnHassink: ooooohhhh yes, The Maze of Galious with SCC would be amazing. The first time I heard an SCC song of MoG back in the day I had chills down my spine. If a rearrangement for the game would be made that would be so awesome... I'd think I would have died and used some salt in the death shrine
