In 1993, Sega introduced a smaller, lighter version of the console, known as the Mega Drive 2 in Japan, Europe, and Australia and simply sold as Genesis (without the Sega prefix) in North America. This version omits the headphone jack in the front, replaces the A/V-Out connector with a smaller version that supports stereo sound, and provides a simpler, less expensive mainboard that requires less power.
