Street Fighter Zero 2 for Saturn was released on September 14, 1996 in Japan.
Features an arranged soundtrack. While the Sony Playstation version uses XA-Audio, the Sega Saturn version uses a streaming ADPCM format which allows the background music to loop correctly like in the arcade version.
Exclusive to the Sega Saturn version of the game when compared to the Sony Playstation version is the inclusion of Evil Ryu, EX Zangief, and EX Dhalsim (from the arcade version of Street Fighter Alpha 2), a Survival Mode, and an Art Gallery.
There are characters with alternate or EX versions that can be stored to the Saturn's memory after using these codes to unlock them. Chun-Li (with the SFII outfit) is already stored in memory:
