Please let us know if/when you're able to pinpoint a culprit.
You might want to start with a MSDOS/Win9x bootdisk (www.bootdisk.com) 
to eliminate FreeDOS components as the culprit, and to have a proven 
reference platform.

Once that works, try 4DOS but keep MSDOS's memory manager.
Independently, also try JEMMEX (and/or XMGR and/or HIMEMX with/without 
JEMM386).

Your game seems to be the most obvious situation to demonstrate 
something's not quite right.

So things that can vary:
[1] KERNEL (MSDOS versions, or various FreeDOS kernels)
[2] SHELL (MS-COMMAND, FREECOM, 4DOS)
[3] HMA/XMS driver (MS-HIMEM, HIMEMX, XMGR)
[4] UMB/EMS driver (MS-EMM386, JEMM386)
[5] Combo XMS/UMB driver (JEMMEX)

A not so nice challenge is trying Quarterdeck's QEMM, that's one big 
nightmare :)
