Released by Sega in the early 1990's, the Sega Multi-Mega is a Sega Mega Drive, Sega Mega-CD, and personal CD player combined. In North America it was released as the Sega Genesis CDX; in Brazil it was called the Multi Mega CDX.
The Mega Drive and Mega-CD function requires an external power supply and TV, but the CD player features can be run from battery power.
The Multi-Mega uses the same power adaptor and A/V leads as the Mega Drive model II. These are connected to the right hand side of the unit. Also included is an 1/8" headphone socket, which works for both CDs and games, and a volume control. There is also a line out socket for hooking up to a hi-fi system.
Due to the altered controller port layout, it is not compatible with Electronic Arts' 4 Way Play multitap peripheral or the Remote Arcade System.
The Multi-Mega was not released in Japan, although the design was licensed to Linguaphone, who rebranded the unit as the Linguaphone Education Gear. Very little is known about this version of the unit
Production of the Multi-Mega ceased with the release of the Sega 32X - Sega then announced that the Multi-Mega was a novelty item rather than a full-fledged console. While not designed to be used with the Sega 32X, the Multi-Mega is fully compatible with it.
Sega would later attempt to package a Mega Drive and 32X into one unit as the Sega Neptune, but this console did not leave the prototype stage.
