After 9 months of work (random laziness / sidetracking!) I've finally released the Mega Man 3 cover playthrough. You can see it here:
This is a video of me playing through Mega Man 3 with all the music remixed using the VRC6 expansion in stereo. Headphones are recommended as the stereo was programmed with headphones in mind. Enjoy!
I also released this on Bandcamp (linked in youtube description as well): http://rushjet1.bandcamp.com/album/mega-man-3-remade
