The port of this to PC has not been done correctly. There are unusual framerate and input issues that are inconsistent. If you have played the Mega Man series before you will find yourself baffled as to how many time you'll be hit by projectiles you know you would have dodged, not jumping to the height you know pressing the jump button should take you, finding enemies slow down or speed up their attack patterns randomly where a jump that was timed perfectly is circumvented. Ladders have unusual behavior, they are much slower and trying to drop and shoot on them is difficult as the controls don't seem to be very responsive. Quick Man's stage the lasers were quite literally impossible to get through without using the Flash Man weapon.

The only improvement this collection has over the original games on the NES is that the slowdown is minimal. Everything else feels off, and that makes it virtually unplayable as a precision platformer. The Anniversary Collection from nearly 20 years ago also has more content than this. I've compared this to the console version and there is something particularly flawed with this version. It may be based on your own specs, but as it stands I could not complete Mega Man 3 out of frustration and dealing with these issues in the first 2 games. Finding myself playing worse than I ever have because the controls feel off, no support for direct USB, no volume control, and none of the glitches or bugs in the original games were ironed out so infamous errors like the cloud platform pushing you off the edge in Snake Man's stage in Mega Man 3 are still present.

Precision platforming requires precise controls, and this port is only slightly off, but that's the difference between playing well and having fun and playing with a handicap and being frustrated at jumps and slides you know would have worked if the game were running properly
