Since the original Master System controller only had two buttons, Tec Toy manufactured a six-button controller to go with the game. This controller later became the standard controller for Master System in Brazil.
Street Fighter II' (pronounced Street Fighter Two Dash), released in 1997, was one of the largest Master System games ever created. It was only available in Brazil, where the older consoles were still very popular at the time. As this was an 8-bit title, some cuts had to be made. There are only eight playable characters (Ryu, Ken, Chun-Li, Blanka, Guile, Sagat, Balrog and Mr Bison) and the background is devoid of animation. Some moves were omitted as well, such as Ken and Ryu's signature Dragon Punch.
This version for Genesis has re-worked sounds and voices if you compare it to the SNES version, with less colors, but it was a lot faster on turbo mode because the Genesis was twice the speed than the SNES, giving you the fastest turbo gameplay that will make you hurl.
