as far as i know it never used the internet, it used "KDDI" which used physical telephone switching boards, so you'd need a way to emulate that, and to make things more bleak, these boards are almost impossible to obtain. kinda hard to emulate something that you don't have or know almost nothing about how it worked
that being said marvel vs capcom 2 online would be absolutely awesome
Yeah, it would be cool, to see that game back online. That and mvc2. Anyways, I checked out some info, about that KDDI thing, a few weeks ago. I will admit, It was rather interesting, to learn what it is.
