The 32X is an add-on for the Sega Genesis video game console. Codenamed "Project Mars", the 32X was designed to expand the power of the Genesis and serve as a holdover until the release of the Sega Saturn. Independent of the Genesis, the 32X used its own ROM cartridges and had its own library of games, as well as two 32-bit central processing unit chips and a 3D graphics processor. Despite these changes, the console failed to attract either developers or consumers as the Sega Saturn had already been announced for release the next year.
