Just tried to run it from BODLoader and it worked. At first I thought "but Gladiator will use BODLoadr which actually does that for you, without necessity of using console. Then, tried from console (
Bladex.LoadLevel("stav") ) and it worked as well. It's literally magic. I don't see any rational reason why didn't it work before.
It still doesn't change the fact it's not possible to see it in LED's preview. I even changed stav.lvl and copied used textures to the maps directory so it didn't have to look for them, and still the same.
I changed fog in stav.bw binary @ offset 0x1C from 0.15 to 0.05
$ hexdump -s 0x1c -n 4 -C stav.bw-fog=0.05
0000001c cd cc 4c 3d
(for D3D and
sgi-rOpenGL 0.10 is better)
$ hexdump -s 0x1c -n 4 -C stav.bw-fog=0.10
0000001c cd cc cc 3d
