The GameBoy games do have some interesting variation on the themes that they take from the original NES games. However, this and my other request are unique to the GameBoy games. I should know as I own and have played through all the NES ones (I grew up on Mega Man and especially paid attention to the music from the games). Up until a few days ago, I assumed that the GameBoy games were knock-offs of the originals, so I never bothered with them. I wish I had, as these two now rank among the best Wily songs (if not Mega Man songs in general) of the whole series in my opinion.
I'm still convinced the other one would make a kickass Stevie Wonder mix.
