Super Mario Bros. 2 is an port of the Super Mario All-Stars version of the original Super Mario Bros. video game for the Sega Mega Drive. It was first released some time in 1998 as Super Mario 2 1998. While unconfirmed, it was likely developed by Gamtec. An alternate version of this game that is more well-known, titled Sonic Jam 6, would be released in the same year that features Sonic the Hedgehog as the only playable character.
Both Super Mario Bros. 2 and Sonic Jam 6 were by the same developer, which is evident from the games peculiarly featuring content from or references to both franchises (i.e., sprites of Mario appearing in Sonic Jam 6 and text referencing Sonic in Super Mario Bros. 2). These oddities make it apparent that the game was always intended to be a Super Mario Bros. game, but also make it unclear which game was finished and released first or what the development process of both games were like.
