I know. There were so many great arcade beat-em-ups that got home ports in the early 90s'. I have no idea why X-Men arcade never got a port. Konami ported Turtles in Time, but left both X-Men and The Simpsons games in the arcade.
One of my goals in life is to own a 6-player X-Men arcade cabinet. That thing has to be seen to be believed.
