One of our older forum guys managed to land some cool screen caps that I've got in my database, but apparently for whatever reason it was hard to rip video from that game. I've been eager to land MPEG's of the Iron Man scenes for years.
I've finally got around to setting up my old capture card under Vista, so I'll see if I can get it that way. I probably won't be able to get anything better than 640x480 though.
Marvel vs. Capcom & Marvel vs. Capcom 2 were both on the Dreamcast as well. The second was actually developed for Sega's Naomi arcade board, which used the same system architecture as the Dreamcast mainboard, so the DC ports are probably the definitive home versions.
BTW, isn't the new Iron Man game coming to the Wii as well?
