If Birdie is left standing idle during a match, he will begin picking his nose and flinging what he finds. This will cause one pixel of damage to his opponent. Similarly, if Ibuki is left standing idle, she will eventually refill one kunai back into her inventory.
The first game in the series to be released on home console first. Previous titles were released in arcades before receiving a console port.
Initial roster includes eight mainstay characters (Ryu, Chun-li, M. Bison, Cammy, Ken, Zangief, Dhalsim, and Vega), four characters from the Street Fighter Alpha series (Nash, Birdie, R. Mika, and Karin), and four new characters introduced in this game (Necalli, Rashid, Laura, and F.A.N.G).
Two characters received censorship before release. During her Critical Art, the camera would zoom in on R. Mika's buttocks as she spanked herself. The final release moved the camera up to her face. Similarly, during Cammy's intro animation, the camera would be placed slightly between her legs as she landed on the ground. The final release moved the camera more towards her torso.
