A collection of WADs for officially-supported games in CGDoom. Most were
edited; one option to do that is to use SLADE.

doom.wad:
  A modified version of 1.9 shareware, I don't know what was changed exactly;
  at least sound was removed.

doomu.wad:
  A modified version of Ultimate Doom, at least sound removed.

doomu[1-4].wad:
  Individual episodes, made from doomu.wad by removing unused maps, removing
  intermission and finale screens from other episodes, then removing unused
  textures and patches (while manually preserving textures not used in maps
  but still used in the code like the sky and buttons).

doom2.wad:
  A modified version of Doom II: Hell on Earth, at least sound removed.
