 As with X-Men vs. Street Fighter, Marvel Super Heroes vs. Street Fighter was initially developed for the CP System II arcade system board, which debuted in Japanese arcades in 1997. The game received a port to the Sega Saturn, exclusive to Japan, on October 22, 1998. The Sega Saturn port supported the 4MB RAM expansion peripheral, allowing the developers to create a conversion which retained the original frame rates and tag team system. The game was then ported to the PlayStation in February 1999. Due to the console's limited RAM capacity, the tag team format was switched to the more traditional round format used in other fighting game series, such as Street Fighter. To compensate for the removal of tag team gameplay, several new game modes, such as Hero Battle and Cross Over, were implemented.
