 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 .
