Street Fighter Zero 2 Alpha/Street Fighter Alpha 2 Gold
This is an update of Street Fighter Alpha 2 - Description from Wikipedia
Street Fighter Zero 2 Alpha was released in 1996 as an updated version of Zero 2. Due to presence of additional characters in the English localization of Alpha 2, Capcom produced this update specifically for the Japanese and Asian market. Zero 2 Alpha is slightly enhanced, giving some of the characters a number of new moves, while additional game modes were also added, such as 'Dramatic Battle' (the 2 on 1 game mode from the original Alpha), 'Shin Gouki Mode' and 'Survival'. This update also added classic versions of Ryu, Ken, Chun-Li, Sagat, and M. Bison (in addition to the classic versions of Zangief and Dhalsim featured in the localized Alpha 2) and the Japanese debut of "Evil Ryu".
This game reached North America and the PAL region in the form of Street Fighter Alpha 2 Gold (or Street Fighter Zero 2 Dash in Japan), which, until the release of the Street Fighter Alpha Anthology, was only available on Street Fighter Collection for the PlayStation and Sega Saturn, and further presented the first Alpha appearance of Cammy, previously introduced in X-Men vs. Street Fighter, but lacks the 2-on-1 Team Mode from the arcade game.
The version of Alpha 2 Gold in Street Fighter Alpha Anthology is actually a combination of both, the arcade and console versions, retaining the arcade version's 2 on 1 Dramatic Battle (which is retroactively added to the original Alpha and Alpha 2 as well) and features Cammy as a fully playable character with her own full fledged storyline.
