Mega Man has been ported to nearly every system and in this episode of PortsCenter Ben Paddon talks about them. I didn't know which versions were ports and which were emulated but Ben does and it makes sense when he shows the graphics side by side with the originals. The recent Anniversary Collection on Steam seems to review well but some people note some input lag on those versions but that doesn't seem to show up for everybody.

I wonder if Capcom will just release all of the Mega Man games in one pack on Steam at some point? Hopefully Dr Wright can get them to do that.
