The Sega Master System was an 8-bit cartridge-based gaming platform and preceded the Sega Genesis. Although superior technically to the Nintendo Entertainment System, Sega lost the marketing war and the Sega Master System was left with few titles.
However, the Sega Game Gear hardware is almost identical to the Master System hardware, and thus the games are actually compatible when used through an adapter. (For the technically inclined, the only major difference is in the video output; the Game Gear supports more colors than the Master System does, albiet at a lower resolution.)
