Well you could check speedrun.com
It's nothing too crazy, just abusing advanced mechanics, doing everything really fast.
Shame it's any% race, it would be better if they ran B and C sides :/ The main game isn't super impressive, while later B sides and C sides are straight up insane.

After the event early this year I spend a whole month watching nothing but Megaman speedruns (specially the more insane fangames), but there is something special about watching the runs as they are happening.
