Compatibility
In addition to playing games, all of the Saturn models could play music CDs, CD+G, and CD+EG discs. A software disc was sold by Sega to allow the playing of PhotoCDs ('Photo CD Operating System'). An MPEG decoding hardware module was released by Sega, JVC and Hitachi, allowing VideoCD playback. JVC later released a VideoCD module that included the software for displaying PhotoCDs, eliminating the need for a software disc. However, these modules were released in Japan and Europe only due to the popularity of the Video CD Format. In order to use one on a North American Saturn, a region converter must be used.
There were some titles that could be played on both North American and Japanese consoles, with Street Fighter Alpha 2 being one of the titles that could be played on both regions systems without a converter. Scud: The Disposable Assassin, which was only released in the North America, was compatible with both European and Japanese Saturns, in addition to North American Saturns.
