Street Fighter Alpha 3 Upper is a compressed version of the original game and lacks several stages and music tracks from the previous arcade and console versions, although all the characters are present. In addition, Eagle, Maki, and Yun, all of whom were characters from Capcom vs. SNK 2 were added to the game. Only a few character voices were included in this version due to storage limitations, which the developers worked around by having characters share voice samples, modified with real-time pitch shifting, such as using a higher pitched version of Ken's voice for Sakura's attack calls.
