ZDoom

I know only two ways to change the default difficulty to UV:

1. Set the skill parameter to 4 by launching GZDoom with -skill 4
2. Make a tiny mod with just a mapinfo.txt file containing only the following block (zipping the mapinfo.txt file should be enough). It'll override the UV difficulty of all Doom-based games, making it the default skill. Load it after maps and mods altering the skills if you want to override them as well, else just put it in your autoload.

skill hard
{
SpawnFilter = Hard
PicName = "M_ULTRA"
Name = "$SKILL_HARD"
Key = "u"
DefaultSkill
}

Hi there.

Like many other source ports, like doom retro, dsda or nugget doom (also woof) I can set UV to default difficulty.
I want to do the same on gzdoom.

Is feasible?
