[The Protomen] How long does it take for the sniper to kill Emily, Wily to take over the city, Protoman to e killed and for Megaman to come to confront Protoman?

At least two generations, maybe three.  Long enough for the City to abandon all memories of freedom and for Dr. Light to be nearing the end of his life as a refugee from Wily's hunters.

The theme of the album goes from rugged acoustics to heavy synths during 'How the World Fell Into Darkness', outlining the City's transition from an agrarian, pre-tech society to a futuristic dystopia run by Robot Masters.  The process was accelerated by the automated workers, but it still would've taken time to prepare everything, time for Wily to solidify control in his Tower, time for Joe to be born and grow up under the regime.

After Joe's death, Dr. Light spends many years building Protoman in secret, going very slowly so as not to arouse suspicion.  When Protoman falls, Dr. Light spends more years in despondency before building Mega Man, who fulfills Protoman's original purpose.  At his victory, the people of the City cry out to Mega Man, not as a savior, but as a new leader.  Years under Wily's rule has atrophied their will to freedom, and they look to Mega Man only as another iron fist to rule them.
