Got CotM and it looks and plays great. My only gripe is that I find it easy and natural to go into a save room and save the game, and then shut the power off. Bad idea since you lose all your progress if you don't first exit the virtual console. I wish power off automatically exited the VC instead. Oi, I gotta get in the habit of creating restore points frequently so if I ever did forget to exit the VC, I wouldn't have to go too far back.
edit: oh, never mind on that gripe. i guess it does save when you enter a save room. if you power off right after you save, you can access the save again from the title screen when you start it up again.
