Street Fighter Alpha 3 for Sega Dreamcast incorporates all features from the PlayStation version while introducing a distinct World Tour mode. Characters Guile, Evil Ryu, and Shin Akuma are available, with Shin Akuma accessible through a specific input. The game also includes an online mode for high score tracking and a Saikyo Dojo mode, where players face off against a formidable opponent from an online pool, refreshed weekly.
The Dreamcast port of Street Fighter Alpha 3 uses all the added features from the PlayStation version but features a different World Tour mode. Guile, Evil Ryu and Shin Akuma are immediately selectable, although the latter still shares a slot with his regular counterpart and is playable via a special button combination. An online mode was added, allowing the player to display their high score. In addition, a Saikyo Dojo mode was added, which pits a character that the player has built up in World Tour mode against a very strong opponent who had to be downloaded from the Internet and changed every week.
