I played this again many years ago on Xbox when the Disney Afternoon Collection came out, along with Rescue Rangers 2, DuckTales 1 & 2, and Darkwing Duck.
The music for these fans was really great, owing to Capcom. DuckTales is basically an unofficial mini Mega Man soundtrack at times (Moon Stage, Transylvania Stage, Mine Stage). Many of the themes from Darkwing Duck also sound like they come from Mega Man 3 specifically, like the ending theme (very bluesy).
