The Sega CD or The Mega CD was one of the peripherals that Sega developed to extend the life of its 16-bit console, Mega Drive (or Genesis in the United States).Thanks to this peripheral, the speed of the central processing unit was increased, the graphic capacity was improved and, how could it be otherwise, it allowed the reading and reproduction of CDs.The advantages of games on CD were obvious. With greater storage capacity, the console was able to put on screen games with impressive graphics, such as Final Fight (the best home version of this Capcom brawler) or interactive adventures based on Full Motion Video, such as Jurassic Park or Night Trap.

The first Sega CD model (or Mega CD in Europe and Japan) was attached to the base of the Mega Drive and had a front loading system, using an automatic tray. There are slight differences between the Japanese, European, Korean and Australian versions, but all three had a series of headlights that indicated when the CD was inside, each time the console read data, and if the peripheral was on.It was connected to Mega Drive I and II through a side expansion port, and it was launched in Japan in December 1991. In terms of technical specifications, it had a Motorola 68000 CPU just like the one in the console itself (which did times of coprocessor). The machine was completed with a 32-bit GPU developed by Sega itself and 856 KB of RAM. It was an expensive model to make, and it was abandoned when the console was redesigned.

There wre various variants of the Sega CD they include, Mega CD MK II, JVC Wondermega, Multimega, Pioneer Laseractive, Aiwa CSD-GM1.
