Super Mario Kart
Notable in the development of "Super Mario Kart" was its use of Mode 7 graphics. First seen in "F-Zero", Mode 7 is a form of texture mapping available on the SNES which allows a plane to be rotated and scaled freely, achieving a pseudo-three-dimensional appearance. 1UP.com have credited the use of Mode 7 with giving the game graphics which at the time of release were considered to be "breathtaking". Retrospective reflection on the Mode 7 visuals was mixed, with IGN stating that the once revolutionary technology now looks "crude and flickery". "Super Mario Kart" featured a DSP (Digital Signal Processor) chip; DSPs were used in SNES games as they provided a better handling of floating point calculations to assist with three-dimensional maths. The DSP-1 chip that was used in "Super Mario Kart" went on to be the most popular DSP chip to be used in SNES games. The music for the title was created by composer Soyo Oka.
