September was the first revision of the game, but most arcades didn't get the game until October 1993.
Here is a list of changes from previous SFII games :
* New title screen with new music.
* Completely new portraits for all characters. M. Bison now has a winged-skull on his hat instead of a star.
* New endings for the bosses. The last part of Chun Li's ending is also modified, letting the player choose whether she should now live a normal girl's life or continue being a detective.
* Vega no longer climbs the fence on his stage prior to doing his 'Flying Barcelona Attack' or 'Izuna Drop' moves. He now just jumps to the edge of the screen and jumps off, as he does in the other stages.
* Voice samples for all characters and announcer re-recorded with different actors. Each character now have their own unique voice so there is no more shared voice samples (e.g. the male 'KO' scream).
* Background music playback is handled differently. The background music will play continuously from Round 1 to Round 2 until a character causes the KO sign to flash on Round 2, which will trigger the 'Heavy Damage' version of the music. From Round 3 onward, the music is played in the same format as in previous SFII games.
* Four completely new stage backgrounds with new background music to accompany the New Challengers.
* Color schemes for the 12 original stage backgrounds have changed once again :
1) Ryu stage : The sky is now near evening, and the moon is now white with a touch of light blue.
2) E. Honda stage : The walls are now light blue, and the big picture (excluding the sun) is now red-orange.
3) Blanka stage : The vine where the snake is coiled is now light green, and people to the right have changed a bit. The river behind the village is now a clear blue.
4) Guile stage : The sky is back to daytime, and the people in the background are now dressed in blue. The symbol on the ground is back to blue, but the missile linings are still red.
5) Ken stage : The tugboat has been replaced with a yacht, and a few of the people to the right have changed a bit.
6) Chun Li stage : The sky is now sunset, the two customers now wear orange, and the 2nd sign is back to red.
7) Zangief stage : The stage floor is now green, and the area to the left is now red. In addition, the fence on the left foreground is now lowered a bit.
8) Dhalsim stage : The curtains and stone floor are now green, and the carpet is back to red.
9) Balrog stage : While the stage floor is still purple, the 'Las Vegas' on the floor is now yellow. The car to the left is now blue, and the car to the right is now green. The guy throwing confetti at win/lose, the guy next to the car to the left and the guy next to the car on the right have changed.
10) Vega stage : The stage floor now shows off a green hue, and the fence now comes crashing down at the start of the fight.
11) Sagat stage : Buddhist statue is still gold, and now it's sunset. In addition, a big city is now visible in the distance.
12) M. Bison stage : The sky is now back to daytime, and the guy sitting Indian style praying (and stands up angrily after breaking a big statue) is now dark-skinned. The roof of the palace is now red with green trim, and the linings on the giant bell that were previously red are now black.
A special version of this game is known as "
Super Street Fighter II - The Tournament Battle".
While New Challengers Cammy, Fei Long and T. Hawk were created by Japanese employees at Capcom, the Jamaican kickboxer Dee Jay is the first and only Street Fighter to have been created by an American Capcom employee (James Goddard). Dee Jay's pant leg was originally going to have 'MANTIS' written on it instead of 'MAXIMUM'. It was changed so that when the sprite was flipped over (when Dee Jay faces the opposite direction), the letters would not appear to be backwards. That is, all of the letters in 'MAXIMUM' look the same when flipped over, but the 'N' and 'S' in 'MANTIS' will be backwards when flipped.
Fei Long is Capcom's homage to Bruce Lee.
Sony Records released a limited-edition soundtrack album for this game (Super Street Fighter II Arcade Game Track - SRCL-2822) on 21/01/1994.
