Where in the World is Carmen Sandiego? for the Master System adapts the computer original's gameplay into a side-scrolling format. Players directly control a detective through city environments, entering buildings to question people and using phone booths to input suspect characteristics such as eye color (replaced with vehicle in this version). If the player is on the correct trail, the suspect may appear and take a shot that must be jumped over to avoid losing time.
A direct port of the Game Gear version of Earthworm Jim was also brought to the Master System. However, it only has 4 levels, and the boss in "What the Heck?" is missing.
A Rom Hack of the 8-bit version of Sonic the Hedgehog for the Sega Master System that adds new levels and lets you play as Boxguy, features custom levels, graphical changes among other things.
