FreeDOS (and MSDOS) kernel and command are in no way hardware
dependent; exclude them from bug searching if just every game fails.
single failure might be possible, but not *every* game.

there are 2, more or less, 'hardware' dependencies:

HIMEM tries to find out how much and where memory exists.

(J)EMM386 tries to find where are regions in A0000-F0000 occupied by
hardware; and often enough got this wrong (not counting the bazillions
of times where it got it right as these cases are not reported on the
internet;).

it might be the BIOS reporting available memory above 1MB in a strange way,
misunderstood by HIMEM/EMM386, leading to trouble.

or it might be EMM386 misunderstanding some adapter memory
requirements in the a000-f000 region.

just my 5 cents.
