Street Fighter II′ - Hyper Fighting, known in Japan as Street Fighter II Dash Turbo (ストリートファイターⅡダッシュターボ Sutorīto Faitā Tsū Dasshu Tābo?) and officially promoted as Street Fighter II′ Turbo - Hyper Fighting, was a minor update released in response to the proliferation of modified bootlegs of Champion Edition. Released on December 1992 (eight months after Champion Edition), Hyper Fighting increased the game speed and added new special techniques for some of the characters such as Dhalsim's Yoga Teleport and Chun-Li's Kikoken. All of the characters received new color schemes; the new scheme became the default scheme, with the original scheme available as the alternate for all characters except M. Bison, who still used his original scheme as the default and the new scheme as the alternate. Also, one of the most recognized hacks of this game would be Street Fighter 2 Rainbow Edititon.
