Very nice!
Very impressive. Great juxtaposition of sounds and synths that emulate the games. A segment that appeared at about 2:10 reminded me of a remixed, counter-melody version of Air Man's stage from Mega Man 2. Awesome.
What synths did you use to recreate the sound so well? (I've always been curious, because I would like to try it sometime in the future as well) :)
Rock on.
