Mega Man is the first game in the famous series that now comprises games on many different systems as well as several television shows and comic books.
While the other run of this game uses lots of tricks to reach the ending impressively quickly, pirohiko and FinalFighter decided it just wasn't fast enough. In this run, they manipulate an object to appear which allows them to execute arbitrary code and warp to the credits, all using only controller input. For an advanced explanation of how it works, check out the submission text.
WARNING: There are flashing lights during the level select screen which may cause epileptic seizures to those affected.
Watch this run on a real console (played back on the US version).
