Super Boy 4 is the fourth and final game in Korean pirate company Zemina's series of unlicensed Super Mario Bros. clones. Most of the graphics in the game are ripped from Super Mario World, with the notable exception of Super Boy himself, receiving an original design for the first time in the series. The game contains 16 stages, loosely divided by 4 worlds, and a final boss stage. In each stage, Super Boy has to reach the end of the stage and break a special block which contains a gem that ends the stage when collected.
