Where to create in the ROMs folder

Doom game files should all exist in a subdirectory of your main Doom folder in your ROMS directory. For example ROMS/Doom/.Sigil or ROMS/Doom/.Ultimate Doom

IWADS and PWADS?

Doom uses two categories to separate content, you have IWAD (internal WAD) and PWAD (patch WAD). You will need to place all IWAD files into their own directory ROMS/Doom/.IWADS. These are the main commercial WADs for Doom, Doom 2, Ultimate Doom, Heretic etc. These are important and are required for games to run.

Creation of Files to run Doom Content

In to root of the ROMS/Doom directory create a text file named <name of game>.doom with the following contents:

parentwad ""
wadfile_1 ""
wadfile_2 ""
wadfile_3 ""
wadfile_4 ""
wadfile_5 ""
wadfile_6 ""
wadfile_7 ""
wadfile_8 ""
dehfile_1 ""
dehfile_2 ""

An Example of Loading SIGIL

parentwad "DOOM.WAD"
wadfile_1 "SIGILC.WAD"
wadfile_2 ""
wadfile_3 ""
wadfile_4 ""
wadfile_5 ""
wadfile_6 ""
wadfile_7 ""
wadfile_8 ""
dehfile_1 ""
dehfile_2 ""

Directory Structure

Example Layout of Doom Games

.
└─ ROMS
   └── DOOM
       ├── .IWAD
       │   └── DOOM.WAD
       ├── .Sigil
       │   ├── SIGILC.WAD
       ├── .Ultimate Doom
       ├── Sigil.doom
       └── Ultimate Doom.doom

As you can see “Ultimate Doom” will requires no additional PWAD files however the directory “Ultimate Doom” still needs to be created.

Compatibility

Please note that not all PWADs you find on the internet will be compatible with PrBoom, if you search for vanilla mods you will have full compatibility.
