STARTING A GAME
As with all DOOM source ports, DOOM Retro doesn’t come with any actual maps. Before you can start using DOOM Retro, map data (in the form of an “IWAD file”) first needs to be obtained by purchasing an official release of DOOM or DOOM II, such as from Steam or GOG.com. Once you have a version of DOOM installed on your PC, you then need to let DOOM Retro know where these maps are. You can do this by using either the WAD launcher or the command-line.
The simplest way to start a game in DOOM Retro is to double-click on the
doomretro.exe icon directly. A dialog box will open asking you “where’s all the data”. Navigate to where DOOM or DOOM II: Hell On Earth was installed and select one of the following IWAD files that DOOM Retro supports:
||DOOM Registered or The Ultimate DOOM|
||DOOM II: Hell On Earth|
||DOOM II: No Rest For The Living|
||Final DOOM: The Plutonia Experiment|
||Final DOOM: TNT – Evilution|
DOOM Retro also supports the countless number of third-party WADs — called PWADs (or “Patch WADs”) — made by members of the DOOM community over the past 20+ years. PWADs need one of the above IWADs in order to work.2 To open a PWAD, click on it, and then CTRL-click on the IWAD from the list above that it was designed for. With the two WAD files selected, click the “Open” button.
If a PWAD is selected on its own, DOOM Retro will try to automatically open the IWAD it requires if both WADs are in the same folder, or if DOOM Retro has previously been shown where the IWAD is.
Alternatively, you may want to create shortcuts for each WAD that you own. To do this, right-click on the
doomretro.exe icon and then click “Create shortcut”. A new file called
doomretro.exe – Shortcut.lnk will be created. Right-click on its icon and then click “Properties”. At the end of the text in the “Target” field, add the
–iwad command-line parameter, a space, and then the full path of your chosen IWAD file. For example:
doomretro.exe -iwad C:\DOOM\doom.wad
To load a PWAD as well, use the
–file command-line parameter, like in the following example:
doomretro.exe -iwad C:\DOOM2\doom2.wad -file C:\wads\brigandine.wad
Double-clicking on the shortcut’s icon will then load the WAD(s) with DOOM Retro.
