Wonder Boy is an arcade game developed by Sega that serves as a sort of precursor to the Adventure Island series. You play as a tribal jungle boy known as Wonder Boy, who must rescue his girlfriend Tina from a dark king with his trusty hatchet and skateboard. It has received ports to the Sega SG-1000 and Master System, the former essentially receiving a remade game due to system limitations and lacking items such as the skateboard.

In this run, Darkman425 plays the SG-1000 version to completion as fast as possible.
