mdmrn, The definitive version of Super Mario Brothers is Super Mario Brothers: Deluxe for the Gameboy Color.
It includes the original game, challenge modes, unlockable art, and a full version of the Japanese version of Super Mario Brothers 2 (Lost Levels in the US) on a single GBC cartridge.
Great version of the game.
