Hopefully!

Weird. Try "cp /etc/dosemu/dosemu.conf ~/.dosemurc" and edit that
manually (if necessary).

I understand. And yeah, it's common. I think (?) it has to do with
address space randomization. So you'd have to do something like
this:   su -c 'sysctl -w vm.mmap_min_addr=0  (or edit /etc/
sysctl.conf)

It shouldn't do that, obviously, but I don't have the app you're
referring to for comparison. Well, I'm not a huge gamer, and I'm so
disorganized that I never have the same files anywhere (my bad). So I
don't have any good tests.

Oh yeah, I forgot, both (DOSEMU and DOSBox) load up Gautier's 3D (Ada)
engine just fine! So try that (though admittedly I recompiled for Ada
4.6.0 since 4.5.3 didn't work):     http://tinypic.com/view.php?pic=6sz87q&s=7
