Super Boy II is an unlicensed Sega Master System game developed by Zemina and released exclusively in South Korea in 1989. It is the direct sequel to Super Boy I and like its prequel, was ported from an MSX version of the game. Despite only working in a Sega Master System, it uses the same graphical mode used to run SG-1000 games, so could be considered an SG-1000 game in disguise.

Like Super Boy I, Super Boy II is a Super Mario Bros. clone, however offers a brand new set of levels not seen in any official Mario game. Due to its MSX roots the graphics are simpler, scrolling is choppy and several gameplay aspects are missing (such as the ability to kick koopa shells).
