Sega
Saturn

After spending two years developing the successor to the Mega Drive/Genesis, Sega launched the Saturn in November 1994.

The console had two CPUs, two GPUs, and a number of other processors which made it difficult to program for and the quality of the software programming varied considerably. A number of games used only one CPU in order to simplify the task, others made full use of the Saturns power. For example, Virtua Fighter 2 used a different CPU for each character during a fight. However, the PlayStation's far higher sales figures and simpler architecture lead to developers favouring Sony's machine and the Saturn received less than a third of the games that the PS enjoyed

Outside of Japan the first overseas models got a redesigned controller (MK-80100). Most people agreed that this was the worst controller that Sega had ever sold their customers. Not only was the d-pad quite inaccurate but the L+R triggers were also difficult to use, often requiring them to be pressed down from the top edge rather than pulled towards the user. Eventually, a version of the original Japanese controller (MK-80116) made it's way overseas for later models of the console.

Although quite successful in Japan the Saturn was far less popular in the U.S. and Europe, finishing the fifth generation race behind both the PlayStation and the Nintendo 64. Sega discontinued the Saturn in 1998 hoping to get a head start in the next gen battle with their new contender, the Dreamcast.

There were a number of variations of the console during its lifespan, a brief summary of the differences follows:

Japan

Early models use BIOS revision 1.00, later models use revision 1.01. Comes with a black controller which has a coloured bottom row of buttons, a red start button and red L+R buttons.

Sega Saturn (unknown): Second Japanese model. Almost white case, same colour as the Dreamcast but with a grey cartridge flap. During production the buttons changed colour from purple to grey and also changed shape from oval to round. Uses the 1.01 BIOS. Comes with a light grey controller with a coloured bottom row of buttons and red L+R buttons.
