The Sega CD is a video game console add-on for the existing Sega Mega Drive. It was originally released as Mega-CD. It allows users to play CD-ROM games.
Sonic the Hedgehog CD was exclusively released for the Mega-CD, although it has since been released as part of compilation games for PCs. The Mega-CD has many other games, such as the controversial Night Trap and Time Gal video games.
Sega also released a combined, semi-portable Genesis/Sega CD unit called the Sega Genesis CDX (Sega Multi-Mega in Japan and Europe). This unit retailed at a lower price than the individual Genesis and Sega CD units put together, but is incompatible with some games and cannot work with the Sega 32X due to overheating and electrical shock issues. The CDX features a small LCD screen that, when the unit is used to play audio CDs, displays the current track being played.
