Graphics The capabilities of the Super FX chip are demonstrated extensively in Stunt Race FX. Each course is constructed of 3D polygons, complete with road bumps and overhead passes. Detailed billboard advertisements also appear throughout each race course. The lack of speed is incorporated into the gameplay by featuring cars that are heavier and clumsier than those included in conventional racing games. History Development In 1991, Nintendo began developing a custom 3D cartridge chip called the Super FX chip with Dylan Cuthbert from Argonaut Software (who is now at Q-Games) as their assistant, so that it could be used in Super NES games to create polygonal 3D graphics. The first game that used the Super FX was Star Fox, which became a success. After the release of Star Fox, Nintendo and Argonaut began conducting various experiments throughout the co-development of the Super FX chip. The development of Stunt Race FX, which was tentatively titled as FX Trax back then, started when Giles Goddard and Colin Reed joined in and later became Nintendo employees. Nintendo used the polygon concept to create a 3D-animated racing game filled with high-flying stunts and obstacles, as well as normal racing. While the game was solid, the overall product quality and timing of release weren't favorable to its success. Nintendo has since discontinued the idea of franchising the series. The one prior incident took form with a canceled sequel on the Nintendo 64 called Buggie Boogie. created the official clay models of the Stunt Race FX vehicles used on the Japanese version's box art and
