Saturn

From LXF Wiki

Sega's followup console to the Mega Drive. Initially designed as a 2D powerhouse, the Saturn had an extra 3D processor dropped into its design late in the development process, to compete better with Sony's PlayStation. Despite some solid ports of popular arcade games such as Virtua Fighter 2 and Sega Rally, the Saturn was eventually overwhelmed by the PlayStation's success, and didn't sell nearly as well as the Mega Drive.
