Mega Man 9 wasn't released on disc to my knowledge. That was a press kit given to the press to promote the game. There was no profit made on it. I have never seen an NES looking box in my local Target with Mega Man 9 inside.
It's probably not their choice and it's probably the Wii's low internal memory and the large file size that is keeping this from going there. Why not just deal with it since that's the situation? You have no evidence there even is an issue in regards to controls. You have no evidence, no proof and nothing from Capcom stating anything about this game yet. How it is you manage to continue your complaining with your foot squarely shoved into your mouth is beyond me.
@Valkyria00-MVC2 doesn't need to be released on VC because the Dreamcast is not a console Nintendo offers on there. Plus all VC games have no upgrades in features, while you would expect online play from this title. WiiWare would be the appropriate place to put this if it were possible.
