32X

The 32X is an add-on for the Sega Genesis video game console. Codenamed "Project Mars", it was designed to expand the power of the Genesis and serve as a transitional console into the 32-bit era until the release of the Sega Saturn. The 32X uses its own ROM cartridges and has its own library of games. It was distributed under the name Super 32X in Japan and South Korea, Genesis 32X in North America, Mega 32X in Brazil, and Mega Drive 32X in all other regions.

Sega unveiled the 32X at the Consumer Electronics Show in June 1994, and presented it as a low-cost option for 32-bit games. It was developed in response to the Atari Jaguar and concerns that the Saturn would not make it to market by the end of 1994. Though the 32X was conceived as a new, standalone console, at the suggestion of Sega of America executive Joe Miller and his team, it became an add-on for the Genesis that made the console more powerful. The final design contained two 32-bit central processing units and a visual display processor.
