>>> TRIVIA
----------
Released in March 1992.
In Japan, the apostrophe-like character on the game's official logo is actually a prime symbol and thus the official title is pronounced 'Street Fighter II Dash - Champion Edition'. Likewise 'Street Fighter II' - Hyper Fighting' is known as 'Street Fighter II Dash Turbo - Hyper Fighting' in Japan.
This game is an enhanced version of 'Street Fighter II - The World Warrior' :
* Added an alternate color scheme for each character and the ability to select boss characters (Balrog, Vega, Sagat, M. Bison).
* Each stage had different background colors from the original (mainly time of day changes), here are the background changes :
1) Ryu stage : now has midnight blue sky instead of red-orange, and has yellow moon.
2) E. Honda stage : the walls are now yellow, the big picture (excluding the sun) is now blue-purple. The 'Victory' sign is now red-orange. The Hiragana Yu on the left is now red.
3) Blanka stage : the snake is now red, and the houses are now wood color.
4) Guile stage : The sky is now sunset. The tinted canopy on the jet is now purple. The symbol on the ground is now red, and the missile linings are now red.
5) Ken stage : The boat is now blue. The 2 guys on top are now wearing brown clothes and teal clothes. The guy in the trenchcoat and hat is now yellow.
6) Chun Li stage : the 2 customers now wear pink, the second sign is now green, the meats on the ceiling are now brown, and the ground is now a darker color.
7) Zangief stage : The floor is now gold and to the left is now copper. The 'Attention' flyers are now red with yellow letters.
8) Dhalsim stage : The stage now has blue curtains, silver stone floor, and blue carpet.
9) Balrog stage : The floor is now purple.
10) Vega stage : The stage now sports a dark blue hue, and the Flamenco dancers are now dressed in pink.
11) Sagat stage : Buddhist statue is gold, and the grass is now a darker green.
12) M. Bison stage : The sky is evening this time.
* New moves were added for some characters.
* The portraits of Chun Li and M. Bison have been recolored.
* Overall hit damage was reduced (favoring combos attacks instead of special moves).
* Special moves were tweaked a bit (i.e. : the fighting styles of Ryu and Ken were distinguishable from one another)
* The main title screen was changed from black to blue.
* Various cosmetic enhancements were made to each character's physical appearance.
* In 'Street Fighter II - The World Warrior', Ryu's stage featured breakable 'Fuurinkazan' signs. These signs have been removed in this game and are not seen again until 'Hyper Street Fighter II - The Anniversary Edition'.
* In Ken's original SFII stage, there were 2 barrels and a stack of boxes which were a single breakable item. From 'Street Fighter II' - Champion Edition' to 'Super Street Fighter II Turbo', there is just a single barrel in Ken's stage. The two barrels and stack of boxes from the original SFII would later return in 'Hyper Street Fighter II - The Anniversary Edition'.
* Sagat's stage in the original SFII stage had a palm tree in the foreground. The palm tree is gone in this game and does not return.
Various unofficial hacks of this game are known as 'V004', 'Accelerator Pt+.II', 'Rainbow', 'YYC', 'Kouryu' and 'Red Wave'.
Pony Canyon / Scitron released a limited-edition soundtrack album for this game (Street Fighter II : G.S.M. Capcom 4 - PCCB-00056) 21/03/1991.
