PrBoom works with multiple released versions of Doom, but has particular naming conventions you must follow if you want the Launcher to see the WAD file.
| Doom | doom.wad |
| Ultimate Doom | doomu.wad |
| Doom II | doom2.wad |
| TNT: Evilution | tnt.wad |
| The Plutonia Experiment | plutonia.wad |
| Freedoom | freedoom.wad |
This is particularily important because the Steam version of Ultimate Doom has the WAD file named doom.wad.
