Are there DOOM utilities for unix?
Obviously, you can’t use any patches for DOS on your SGI executable. You can use people’s homemade wad files once you are registered. Since a Linux port of DOOM is out, many of the wad editors, etc., may be ported soon. (The WAD editor DEU has already been ported to Linux.) Look around the ftp sites; some of the utilities may come with code; port them yourself and then announce them!
