Does marvel vs. streetfighter need a ram cart?

A link to that site in Newbie 101 or in a Saturn FAQ (hint, hint) might be useful.

Yes, see Shin Force for a list of other RAM/ROM cart games.

Is there one universal cart for all games? I found a 4mb Sega brand one on ebay that i might want to purchase. Would that work for all games? If not definately, atleast probably?
