I have started my own full Megaman Game - it has all 8 traditional bosses, an opening stage and 4 Wily Stages.
The link to the project with the download is here:
http://scratch.mit.edu/projects/Proseph/1878728
It only has the opening stage and a started stage select so far; although, you can check out all of the music that will be used in the download.
By the way, Scratch wouldn't allow me to directly upload the game to the website. Sorry for the inconvenience.
