Doom 64 - Ray Traced ships the renderer, not the game. Put the game files
in THIS folder, then run launch-doom64-rt.cmd one level up.

1. Doom 64: Retribution v1.5   (free)
     https://www.moddb.com/mods/doom-64-retribution

   Extract the WHOLE download in here, not just the WAD. It contains
   several files this needs and they are easy to miss one at a time:
     D64RTR[v1.5].WAD        the mod itself
     D64RTR_BRIGHTMAPS.PK3   every enemy eye and glowing panel is masked from it
     DOOMSND.SF2             without it the few MIDI tracks stay silent
     libfluidsynth*.dll      plays those MIDI tracks

2. OGG music pack v1.3   (free, same ModDB page, file D64MUS.ZIP)
     .../addons/doom-64-retribution-ogg-music-pack-v13
   Unzip it here too - that gives you D64MUS.PK3.

3. doom2.wad   -   a DOOM II you own, from Steam or GOG.
   The launcher finds Steam and GOG installs by itself, so you probably
   do not need to copy this at all. If yours lives somewhere unusual,
   the startup check has a Browse button.

The launcher checks all of this on startup and tells you what is missing,
with a link to each download.
