The Sega Saturn has historically been one of the harder consoles to emulate due to its infamously difficult architecture consisting of 8 processors overall and use of quadrilaterals rather than triangles as polygons, resulting in a lack of good options. However, things are looking up for open-source emulators like Mednafen, and to a lesser extent, Yabause.
Sega Saturn supports CD-ROM discs. Also supports Audio CD, CD+G and Photo CDs. You need #Video CD Card for VCDs, later revisions of the Video CD Card negate the need for "Photo CD Operating System" disc software by giving the Saturn native Photo CD support.
Also called the Movie Card in Japan - allows Saturn to play Photo CDs, Video CDs (VCDs) and hardware playback of MPEG-1 (version 1) video in certain games, leading to higher quality FMV for use in cutscenes (and occasionally, gameplay) (similar to the Philips CD-i's Digital Video Cartridge). Later revisions of the Video CD Card negate the need for Photo CD Operator software by giving the Saturn native Photo CD support.
The Taisen Cable is device which allows two Sega Saturns to connect to each other. It can be seen as a console equivalent to a local area network (LAN) setup usually found with computers, where systems are all linked together within a small area. The official Sega-branded Taisen Cable was only released in Japan, however third-party alternatives were released in other territories and a number of non-Japanese games support the device.[1]
Mednafen version 1.31.0 added experimental support for ST-V games that don't require decryption chips or special hardware. Refer to the ST-V section of the official documentation for more details and a list of explicitly supported games.
The Saturn had technically impressive hardware at the time of its release, but its complex design, with two CPUs and six other processors, made harnessing this power difficult for developers accustomed to conventional programming. The biggest disadvantage was that both CPUs shared the same bus and were unable to access system memory at the same time. Making full use of the 4 kB of cache memory in each CPU was critical to maintaining performance. One example of how the Saturn was utilized was with Virtua Fighter's use of one CPU for each character[4]. Many of the Saturn's developers, such as Lobotomy Software programmer Ezra Dreisbach, found it difficult to develop for compared to the PlayStation because of its more complex graphics hardware[5]. In order to port Duke Nukem 3D and PowerSlave to the Saturn, Lobotomy Software had to almost entirely rewrite the Build engine to take advantage of the Saturn's unconventional hardware[5]. Third-party development was initially hindered by the lack of useful software libraries and development tools, requiring developers to write in assembly language to achieve good performance. During early Saturn development, programming in assembly could offer a two to fivefold speed increase over C language[4]. Sega responded to these criticisms by writing new graphics libraries which were claimed to help make development easier[6]. These libraries were presented as a new operating system by Sega of Japan[6].
