If the next Game Boy (or DS) ran any of the Virtual Console systems, it would be a massive success. Come on, who wouldn't lay down a few bucks to play their NES favorites on the go?
I am hesitant to buy games for the Virtual Console if I own the original system and they are readibly availible, but higher resolution is pretty tempting for Ocarina of Time. I expect people to come back here and talk about their experiences (controls, graphics, etc.) after they buy it. Do not let me down.
