Capcom's Mega Man will be making a guest appearance in Smash Brothers this time around complete with mega-buster, a whole pile of
robot master weapons, and his trusty dog Rush.
Rockman 4 Minus Infinity: A completely thorough MM4 hack that tranforms it into a completely different game where the bosses have totally different attacks and AI (effectively, all new
robot masters), you get totally different
weapons, and there are all of these cool effects that totally push the limits of an NES ROM.
