Super Mario Bros. - Genesis - Platformer

Super Mario Bros. is a unauthorized port of game (with the same name) to Mega Drive. It was released as homebrew for the console as SMB4MD. However, as many MD homebrew games, it was sold as a pirate game and it was credited to KDS (Kudos), and most of the times, was bundled with BattleCity (which was also a homebrew port), and also is credited by KDS.
