Street Fighter II': Hyper Fighting (USA 921209)

Street Fighter II': Hyper Fighting (Street Fighter II' Turbo: Hyper Fighting in Japan) is the second upgrade to the Street Fighter II series after Street Fighter II': Champion Edition. It is a simple modification of the game made by Capcom USA (James Goddard), in an attempt to counter the proliferation of the many unofficial hacks available at the time, and to incorporate into the official game some of the most popular improvements made by them, including attack speed and new paddles on certain hacks.

The speed of the game has been greatly increased (hence the Turbo on the console port of the game); and new special moves are available to certain characters, making combat much more strategic.
