I got a copy of Marvel vs. Street Fighter, the one that comes with a 4 MB cart. Is this cart able to be used in all capcom and SNK games that require a cart, since the highest is a 4MB, or will I need a different cart for each game. I know there are 1, 2, and 4MB carts for different games, can a regular 4 work for any. And I know this may be a noob question, but I just got a Saturn 2 weeks ago, and I have noticed on Ebay and other places, it is more expensive to get games with their carts as opposed to just the games that require one themselves.
