Optional add-ons go in THIS folder. Nothing here is needed to play, and none of
it ships with Doom 64 - Ray Traced: these are other people's downloads, loaded
exactly as you downloaded them. Nothing in this folder is modified.

Understood today:

  D64ClassicRecolored.wad            the Cacodemon and the Pain Elemental
  D64ClassicRecolored_OffsetFix.wad  repainted in classic Doom hues
     https://www.moddb.com/games/doom-64/addons/d64classicrecolored
     Either file works. See README, "Art changes", for which one gets which
     sprite offsets right - they differ, and neither is exactly right here.

Drop the file in here and press Re-check in the startup window: the add-on's
line turns green and grows a checkbox that loads it. You do not have to close
and reopen the launcher.
