>>> TRIVIA
----------
Released in February 1994.
This game is known outside Japan as 'Super Street Fighter II Turbo'.
Originally all of the additional features (see Updates section) that were added in 'Super Street Fighter II X' (Gouki, Supers, etc) were planned for 'Super Street Fighter II - The New Challengers', but were left out due to time restraints.
Origins of Gouki : The name 'Sheng Long' comes from the Japanese 'shouryuu', meaning 'rising dragon'. The kanji used in 'shouryuu' was pronounced as if it was Cantonese. One of Ryu's win quotes in the English version of 'Street Fighter II' said, 'You must defeat Sheng Long to stand a chance'. At the time, fans of Street Fighter II thought that Sheng Long had referred to a person - the supposed master of Ryu and Ken, and not one of Ryu's moves (the Shouryuu Ken).
The creation of Gouki comes from an April Fool's joke in Electronic Gaming Monthly magazine where the editors claimed that you could fight Sheng Long in the game by not touching Vega, the final boss of 'Street Fighter II'. Sheng Long would then come out of nowhere and kill Vega, and you would fight him. Sheng Long was supposed to have the moves of Ryu and Ken, but did much more damage and was also faster. To make this joke more believable, fake screenshots were made. Soon after, many fans, believing that the joke was true, flocked to 'Street Fighter II' machines, hoping that they could fight a nonexistent character. When asked about whether the joke was true, Capcom did not confirm nor deny it as the sudden infusion of money into their machines was driving up business; Capcom USA was taken in by the gag, and actually contact Capcom Japan and asked if the Sheng Long thing was legit. Only much later was this joke was revealed as such, by Electronic Gaming Monthly themselves. Ironically, in 'Super Street Fighter II X - Grand Master Challenge', parts of this story became true. Like the joke, Gouki would appear from out of nowhere and kill Vega, and you would fight him, and similarly, Gouki had the moves of Ryu and Ken, and was much faster and dealt much more damage. As many people were accustomed to Sheng Long, many people called Gouki erroneously by the name Gouki Long. The move that was used to kill Vega (the Shun Goku Satsu) was also erroneously called the Vega Killer.
Shin-Gouki, Shin-Gouki and Shin-Gouki : Depending on the kanji that's used for 'Shin', Gouki is of one of several personalities. As regular Gouki (considered to be an evil character by Capcom of America, but just an antihero by Capcom of Japan), he does not condone unnecessary roughness (he helps out those in need and only fights when either under self-defense or when challenged to a match - and any match is a deathmatch in his book). Shin-Gouki found in SFZ2 is just regular Gouki not pulling his punches (it's the unnecessary roughness thing). Another note about Gouki : Gouki lives and trains on the island of Gokuentou, reportedly to have been destroyed in SFZ2 (but Ryu was the only witness) Or, if you believe the non-canonical Pocket Fighter, turned into a tourist trap :-p
All of Gouki's voice samples are actually recycled voice samples from the other male characters.
Sony Records released a limited-edition soundtrack album for this game (Super Street Fighter II Arcade Game Track - SRCL-2822) on 21/01/1994.

>>> GAME UPDATES
----------------
In the American version, Gouki is known as 'Akuma'. All of his dialogue was removed instead of being translated. If you win with 'Akuma' in SSF2 Turbo, he has no victory quotes. His ending is all but completely removed, with only a credit roll if you beat the game with him, along with pictures of his defeated opponents.
In the Japanese version, Gouki had two text endings, which translate as follows...
1) -If the last fight is against Vega-
Gouki : Evil Emperor, you say... nothing more than words. Real victory can only come from a fist. That is all.
There was no one to stop Gouki from that moment onwards.
2) -If the last fight is against Gouki-
Gouki : Something within... what's this ?
?? : I am the shadow of the condemned. You have killed the demon of this curse, and so you shall be condemned no more!
Gouki : I now reside in darkness. Even death is beneath me... excellent!
....That man returned to the darkness and disappeared.
Some characters endings are translated inaccurately (See 'Super Street Fighter II - The New Challengers' entry for details).
Here is a list of changes from 'Super Street Fighter II - The New Challengers' :
* Modified title screen with new music.
* The 'Character Select' screen's background music is changed. The new song is based on the title screen theme of 'Street Fighter II - The World Warrior' (and the other pre-Super SF2 games).
* After each character's ending, a new piece of artwork is displayed for that character. In Ryu's new art, the kanji 'Fuurinkazan' are written on his belt. These are the same kanji that are displayed on the breakable signs in Ryu's stage in 'Street Fighter II - The World Warrior' and 'Hyper Street Fighter II - The Anniversary Edition.
* New artwork in Dhalsim's ending. The picture of Dhalsim and his son is replaced with a new picture of Dhalsim with his wife and son. The photograph on the wall now shows Dhalsim with Sagat and Vega (It used to show two generic guys).
* All bonus games have been removed.

>>> TRICKS AND TIPS
-------------------
* Play as Old-version Characters : Select your character with LP, then enter the code below while the plane flies to the top of the screen then press LP again. If done correctly you should hear a sound and your character's costume colors in their portrait should change. Old-version characters have no super combos and cannot reduce throw damage...
Old Chun Li : Down(x3), Up
Old Dee Jay : Down(x2), Up(x2)
Old Vega : Down, Up(x2), Down
Old Dhalsim : Down, Up(x3)
Old Ken : Left(x3), Right
Old Fei Long : Left(x2), Right(x2)
Old Balrog : Left, Right(x2), Left
Old T. Hawk : Right(x2), Left(x2)
Old Ryu : Right(x3), Left
Old Guile : Up, Down(x3)
Old Sagat : Up, Down(x2), Up
Old Cammy : Up(x2), Down(x2)
Old Honda : Up(x3), Down
* Play as Gouki : At the character select screen : Highlight Ryu and hold for 3 sec., highlight T. Hawk and hold for 3 sec., highlight Guile and hold for 3 sec., highlight Cammy and hold for 3 sec., highlight Ryu and hold for 3 sec., press all 3 punches and Start at the same time at the end of you counting.
* Gouki as final boss : If you reach the final stage on a single credit (no continues), you will fight Gouki instead of Vega.
* Each character has 8 outfit colors. Press LP to choose the new Super Turbo color, MP for the Champion Edition color, HP for the Turbo color, any Kick button or the Start button for one of 4 new colors, or hold any attack button for 3 seconds for the secret color. If you use the old version of a character, you will see that character's original 'Street Fighter II' outfit.
* End credits : If you beat the entire game without continuing, you will get to see the ending credits. If you don't lose a single round, the new ending artwork for each character is shown during the credits. Otherwise, you will see demos of the different characters fighting each other on various stages during the credits.
