The Sega CD, originally released as the Mega-CD (メガCD, Mega-Shī Dī) in most regions outside of North America and Brazil, is an add-on device for the Sega Genesisvideo game console, designed and produced by Sega. It was released in Japan in 1991, North America in 1992 and in PAL regions in 1993. The device adds a CD-ROM drive to the console, allowing the user to play CD-based games and providing additional hardware functionality. It can also play audio CDs and CD+G discs. While the add-on did contain a faster central processing unit than the Genesis, as well as some enhanced graphics capabilities, the main focus of the device was to expand the size of games.[1] The Sega CD sold 2.24 million units worldwide[2] and was officially discontinued in 1996.[3]
There are 207[a] games on this list. 57 were released only in Japan, 38 were released only in North America, and 4 were released only in Europe. Of the games released, there are six titles (marked with a † in the title for the game) that were also released in formats that used a combination of the Sega CD and the 32X. Games that were announced or reported to be in development for the Sega CD, but never released, are located at the list of cancelled Sega CD games.
