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.

A video game accessory is a distinct piece of hardware that is required to use a video game console, or one that enriches the video game's play experience. Essentially, video game accessories are everything except the console itself, such as controllers, memory, power adapters (AC), and audio/visual cables. Most video game consoles come with the accessories required to play games out of the box : one A/V cable, one AC cable, and a controller. Memory is usually the most required accessory outside of these, as game data cannot be saved to compact discs. The companies that manufacture video game consoles also make these accessories for replacement purposes as well as improving the overall experience. There is an entire industry of companies that create accessories for consoles as well, called third-party companies. The prices are often lower than those made by the maker of the console (first-party). This is usually achieved by avoiding licensing or using cheaper materials. For the mobile systems like the PlayStation Portable and Game Boy iterations, there are many accessories to make them more usable in mobile environments, such as mobile chargers, lighting to improve visibility, and cases to both protect and help organize the collection of system peripherals to. Newer accessories include many home-made things like mod chips to bypass manufacturing protection or homemade software.
