D. Stuart Riffle, who now has a career as a software developer, is the "S" in S&M software, with his wife seemingly being the "M". He is also referred to as being the "Ruler of the Entire Universe" in the game credits, although this seems to refer to the in-game universe rather than the real-world universe. His Bipbop 1 & 3 games were released as freeware after he was contacted by Ross' Game Dungeon.
