Very cute. From the title screen, it looks like he used the updated NES version from the Virtual Console. I'm curious how he got it. Is it even possible to pull VC ROMs off your Wii? A quick Google suggests that if he downloaded it, he would have had to go out of his way to find that version, as opposed to just using the original NES version.
EDIT: Here's the backstory, in case anyone hasn't seen it yet.
