The original six NES Mega Man games have been released on iOS and Android devices, and you’re better off not buying them. We’re very sorry to be a bummer about this, but it’s best you hear it from a friend.
The idea that the games have had their speed “adjusted” is somewhat misleading, as the reality is that the framerate on these new releases is abysmal. The games themselves have also been edited a bit from the originals… More at Polygon.
That’s a real shame.
