Comment (by dfabulich):

 I tried that, actually! The problem is that KQ6's code assumes that the
 low-resolution graphics _are_ being stretched. So I starting fixed bug
 after bug after bug: rendering garbage on the screen after dismissing the
 opening "Sierra" movie, opening and closing the icon bar, misaligned
 inventory.

 ScummVM has a few script patches checked in, but this would require a
 _lot_ of script patches.

 I gave up on it after a while, but I guess it's possible in principle to
 find (gulp) all of the bugs and fix them.

 A simpler approach would be to render render 320x200 graphics to 10x11
 pixel blocks (matching the original Windows release's 1:1.1 pixel shape),
 and 640x440 graphics to 5x5 pixel blocks, using OpenGL to rescale the
 resulting image to fit the user's window. That wouldn't require a massive
 bug hunt.

 Would anyone want a PR like that?
