Mario 16 (1996) is an unlicensed (Unl) NES game, meaning it was produced and distributed independently, without authorization from Nintendo. The title suggests a possible unauthorized attempt to create a game within the popular Mario franchise. Further details about the game's gameplay and development would be difficult to confirm given its unlicensed nature. This makes it likely a fan-made creation.
