I've updated prboom to 2.4.1. It's a Doom engine port to Linux, and it went with some intense QA testing as usual.

It just required to get the shareware doom.wad file from DoomWorld, it then worked as a charm :)

Doom noir looks like an interesting mod to test, it transforms the graphics to black and white, hilighting only red colors. It makes some gory and film-noir effect, a la Sin City.
