As Zemina went into another direction with part 3 of their Super Boy series, Clover filled the void for an MSX Super Mario Bros. 3 clone. The game features the intro and level map from the original, but the levels are composed differently, with new enemy types, like flying Goomba bombers (probably meant to replace the mini-Goomba throwing ones). It's also significantly shorter than the original. A series of hacks of this game titled Super Bioman, with new levels and some exchanged graphics were sold by Hello Soft and Segye-ro Electronics.
