You could probably monitor the DOS VM to scrape camera/object matrices, render the static world in a huge GL (or what have you) display list, and then the other objects. The mesh formats were reverse engineered long ago.

Not sure how viable that would be, but if the rotation within the game is high-res enough I imagine one might render the same scene four times each with a rotation offset equivalent to half a pixel. Then combine those to a whopping 640x400 image :)

Yes, for DOS games.

However, DirectX games were much easier... I remember patching F-22 Total Air War (a DiD Flight Sim) to support higher resolutions back in 2001 or something, and it was just 3 bytes or so that needed changing, and worked surprisingly well...

(Seem to remember a bit of a community doing it in various games on the simhq.com forums back then.)

Yep.
