Capcom Fighting All-Stars: Code Holder was a 3D fighting game scheduled for release in arcades and the PlayStation 2 in 2003. Following negative feedback from a limited beta test in Japanese arcades the project underwent more months in development before finally being cancelled altogether. The philosophy behind All-Stars, in which flagship characters from different Capcom series compete together, was revived and realised with Capcom Fighting Evolution in 2004. There were nine returning characters proposed for All-Stars, the vast majority of these coming from the Street Fighter universe; Ryu, Chun-Li, Alex and Charlie plus Haggar and Poison from Final Fight and Batsu and Akira from Rival Schools. Indeed only Strider Hiryu does not fit into the Street Fighter universe somewhere. All-Stars was also set to introduce four new characters; D.D., Rook, Ingrid and Death. Ingrid's design and moveset was resurrected for Capcom Fighting Evolution and she formally became included in Street Fighter canon (despite her incongruity) in Alpha 3 Max. Poison had been a playable character in 1999's Final Fight Revenge and would become playable again in Street Fighter × Tekken in 2012.
In 1994 Living Beat Records released a remixed Street Fighter II 12" soundtrack ostensibly for use in nightclubs (LBET 027). The record contains six tracks; two on side A and four on side B. The record's subtitle World Warrior is something of an anachronism considering that the recording's cover art is from home editions of Turbo and contains tracks entitled 'Hyper Fighting Club Mix' and 'Turbo Club Breakdown'. The soundtrack is also available on CD (LBECD 027) and, rarer still, on cassette (LBEMC 027). A 7" single version (LBES 027) containing just two tracks also exists.
Two unused subtitles for Super Turbo exist in the arcade's ROM despite being pulled from the final product. Internationally the game was going to have the subtitle The Ultimate Championship, in-keeping with the tradition that began with World Warrior. Eventually this subtitle was dropped but an indication of how late this decision was made is given by its appearance in early promotional material and even a prototype cabinet. To some extent it is still recognised officially; it is included on the Super Turbo logo in the Street Fighter Eternal compendium, for instance. In addition to this strapline, a stylised letter 'Z' that is designed to wrap around the 'II' in the title logo has also been found in the game data. This too was ultimately unused but it is intiguingly analogous to the letter 'X' that does appear in the final version of the game in Japan. So whilst the game retained its tinselled title in Japan as Super Street Fighter II X: Grand Master Challenge internationally the simplified title Super Street Fighter II Turbo was preferred.
A scientist wearing a hazmat suit as seen in the background of Seth's Secret Laboratory stage in Street Fighter IV is also visible taking photographs in the background of the 'break car' bonus stage in Super IV. In the game's development blog, Natsuki Shiozawa confirmed that this S.I.N. employee and the man with a camera wearing short trousers in the Crowded Downtown stage are one and the same. In the fight with Seth, one of these scientists can be seen sinking to his knees when one of the fighters is defeated.
In addition to the 'what-if?' characters found in 1997's Marvel Super Heroes Vs. Street Fighter (Cyber-Akuma, Mech-Zangief, Sunburnt Sakura and Shadow) an alternate, 'dark' version of Chun-Li debuted in 1998's Marvel Vs. Capcom: Clash of Super Heroes. In symmetry with Shadow, the brainwashed version of Charlie, this form of Chun-Li is known as Shadow Lady and has similarly been transformed by M. Bison into a cyborg (complete with drill arm and rockets!) Shadow Lady even has an alternate, maroon colour scheme and in Ultimate Marvel Vs. Capcom 3 Chun-Li has a colour-scheme designed to mimic Shadow Lady (although it's merely a cosmetic change; no drill attacks!) Although she is an extremely niche character the developers of SNK Vs. Capcom Card Fighters DS saw fit to include a Shadow-Lady card in 2006.
As Gill is unplayable in New Generation the announcer's sound effect 'Gill Wins', which exists in the ROM and would have been used in versus matches, cannot be heard in-game under normal circumstances. By use of a hack, however, it is possible to select Gill in versus matches and trigger the sound effect. Intriguingly, a version of the festive 'Jingle Bells' theme can also be heard in the game's sound test mode (number 20) but isn't heard anywhere in-game. With Sean's stage taking place in a Christmas themed New York City it is plausible that the theme was originally intended for this location.
Namco × Capcom is an action RPG/tactical RPG hybrid game for the PlayStation 2 developed by Monolith Soft and featuring characters from games produced by both Namco and Capcom (2005). In so far as game centres on a cast of original characters with pre-existing characters playing supporting/cameo roles the game has a kinship with the Adventure Quiz/Capcom World titles from the early '90s. The host of characters is simply too large to list in full: suffice to say that Ryu, Ken, Chun-Li, Cammy, M. Bison, Akuma, Sakura, Rose, Juli, Juni, Karin, Haggar and Guy all make noteworthy appearances alongside Hideo and Kyoko from Rival Schools and the four protagonists from Captain Commando. Namco and Capcom would famously unite again for the Street Fighter/Tekken crossovers.
