Um, just because Capcom apparently needed a 20 man team to do MM9/10 doesn't mean the rest of the world is as wasteful. Why would you even need to market a Megaman game especially one that looks like it could be made on the 8-bit system? The only guys who would be buying it are the hardcore Megaman fans and you'd just need some guy to post on the forums these guys frequent in. It's not like some brand new guy is going to say "OMG this 8-bit looking game looks awesome, I better check it out!" There are far more sophiscated game made with whatever-Makers, let alone people who actually try to make a good game, so I think it's insulting to say that Capcom contributed to help make a game that'd be mistaken for NES technology.
At this point the most important support Capcom can provide is the graphical assets and that they wouldn't be slapping people with copyright issues or some "Megaman vision", like what happened to Megaman Zero 1 when you were supposed to fight Megaman X as the last boss but it was changed the last moment because Capcom intervened so you get a mostly nonsensical story, and I'd say Copy X is gimped because he's not the real X, so the fight wasn't nearly as cool as the fight against Omega, who is the original Zero.
