2024 KEX Engine Version (Steam)

Bethesda updated the DOOM + DOOM II listin to the new KEX Engine as of 2024-08-08.

The KEX Engine version spreads out the files and assigns a random BethesdaNet ID number to WADs as their filenames.

KEX Engine - Getting the Downloaded BethesdaNet

Prerequisite: First, download the add-ons from the featured mods list.

From the Main Menu, select a game (e.g., DOOM II) → Mods Menu → Featured Mods.
For some mods that are no longer on the Featured Mods list, go to Mods Menu → Browse and search for them to match the Unity Version set.

Where are the BethesdaNet WADs located?

Each downloaded .wad has its own sub-folder based on an internal ID.
The folder contains:

The .wad file
An index.json file

Example SIGILII in Steam:

~/.local/share/Steam/steamapps/compatdata/2280/pfx/drive_c/users/steamuser/Saved Games/Nightdive Studios/DOOM/bnetwads/585d6a05-e50c-4ad7-aac7-726d35d23a50/

585d6a05-e50c-4ad7-aac7-726d35d23a50.wad
index.json

Opening index.json:

{
    "id" : "585d6a05-e50c-4ad7-aac7-726d35d23a50",      // Mod's BethesdaNet ID
    "title" : "SIGIL II",                               // Mod Title
    "version" : "2ed265fd-6fdf-45a5-a078-35811549ce3b", // Current uploaded version
    "wad" : "585d6a05-e50c-4ad7-aac7-726d35d23a50.wad"  // The WAD file
}

This reveals that 585d6a05-e50c-4ad7-aac7-726d35d23a50.wad is in fact SIGILII.WAD.

You can then copy it into:

retrodeck/roms/doom/ and rename it to:

SIGILII.WAD.

Unity 2019 Version - Getting the Official Add-ons

Prerequisite: First, download the add-ons from within the 2019 Unity Version.

From the Main Menu, go to the Add-ons Menu.
Download all available add-ons.

How to Grab the Files?

Each add-on file is located in the WADs/ folder from the previous step. Each folder is named with an ID number that corresponds to the add-on.

Example: Sigil

Sigil has the ID 4, so it is located in /WADs/4/.
Inside that folder, you will find images and a file named 4 (no extension).
That 4 file is the actual SIGIL.WAD.

To use it:

Copy /WADs/4/4
Intoretrodeck/roms/doom
Rename it SIGIL.WAD
