On SDL, there's an SDL2+minimal ANSI C environment for plan9/9front called NPE.

The SDL2 audio and video libraries are just shims against 9front drawing/audio functions, and often they just work.

Plugging a DOS game to an SDL(2) library won't "just work".

Some concepts are inherent to the hardware and the O/S.

Hardware example: EGA (not the case of doom, but of other, slightly older games) uses bitplanes, it's not just an array of byes; audio cards used specific drivers.

O/S: timers may need to be emulated, as the game may not have a straightforward game loop; due to this, even exiting cleanly may not be trivial to implement.

Not an issue for Q1, it wasn't for neither EGA or VGA for DOS exclusivelly, they had DOS, Windows and Unix versions since day 1.
