Street Fighter Zero 3 was re-released for the arcades in Japan in 2001 under the title of Street Fighter Zero 3 Upper (officially promoted as Street Fighter Zero 3↑). The game was released for the Dreamcast-based NAOMI hardware (rather than the original game's CP System II hardware) and features all the added characters from the console versions of the game. Upper also allows players to upload any customized characters from the Dreamcast version of the game by inserting a VMU into a memory card slot on the cabinet. A Game Boy Advance version developed by Crawfish Interactive was released in 2002 under the title Street Fighter Alpha 3 Upper. The port is compressed and lacks several stages and music from the previous arcade and console versions, although all characters are present. In addition, Eagle, Maki and Yun, all whom were characters from Capcom vs. SNK 2 (released during the previous year), were also added to the game. Only a small amount of 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 Ken's voice for Sakura's attack calls.
