At last, the cursed verification mail arrived my mail, after two weeks waiting for.

Ok, I have a small doubt I was trying to find at the documentation, elsewhere, but i was not able to find.
I have made some MODs and maps, and i usually set the map so GzDoom needs to make use of "Doom Legacy" ligtning mode. At the readme.txt file, i explain to player to configure that, or the map will be weird and darkish.
Also, i usually provide a .BAT (or .SH for Wine Linux users) to allow player launch easily the game, something like "gzdoom.exe -iwad doom2.wad -file mymod.wad textures.wad sprites.wad sound.wad"
And the question is: How can i made to set the lightning mode to "Legacy mode" from de .BAT file? Is that possible?
That would avoid the players to change configuration manually, and the most important, dont forget that.
Thanks for answer.
