_________________________
Super Boy 3 is the third Super Boy game, made by Zemina and released exclusively for the MSX in 1991. The game is unrelated to the other Super Boy games, featuring different graphics (ripped from Super Mario World), different music, and different physics. The design for Super Boy is also changed, now being based more around Mario's design in Super Mario Bros. 3. Super Boy 3 was followed by the Master System title Super Boy 4 in 1992.

The game has been drastically changed since Super Boy I and Super Boy II. Instead of being another variant of Super Boy I, the game has an all-new setting and story. Instead of having graphics ripped from the original Super Mario Bros., the game features graphics ripped from Super Mario World, but with reduced colors to fit the MSX's technical limits. The scrolling is notably better than the scrolling in Super Boy I and Super Boy II, due to shortened load times between screens. The game also features enemies from Super Mario World rather than including the Super Mario Bros. enemies, as used in the previous two games.
