For windowed you could simply record the whole desktop at 60fps while keeping a reference input window visible somewhere. But there is no real input lag problem with windowed...
Fullscreen would be more tricky, I can't think of an easy way to do this :/
I'm not sure if I understand your proposal. Sure, you could record the whole desktop with a window showing the current buttons being pressed, but I don't think the game itself has any sort of service menu or "buttons pressed" screen. I doubt there would be much legitimacy in trying to correlate with ship firing and/or movement, since there is likely a fundamental delay/acceleration to be had with either animation (which would exist on any version of the game).
The only way I can imagine trying to truly observe how much "extra" lag there is introduced in the Steam version would be to mirror the same input to a lag-less console (or emulator) playing the game and observe any difference in ship responsiveness.
If I am mistaken with any of this, please feel free to correct me.
MrMonkeyMan, thanks for the feedback. I'm starting to feel like I shouldn't even bother with this port. It is a damn shame, since I was really, really looking forward to this release.
