Mega Man Legacy Collection - which includes the first six NES games and some nice extra features - isn't far away in the West. In Japan, however, it's out now, and Capcom has celebrated the 3DS version's release with a couple of rather neat HOME Themes.
You can see videos of these below, with one having a rather fun animation and the other riffing on stage openings.
It wouldn't be surprising if these are available in the West once the collection arrives in Europe / North America on 23rd February. Will you be picking these up?
