Doom with any source port | Steam overlay
By 1200
In this manual I'll tell you how to run any Doom game with source port, such as Zandronum, Zdoom, gzDoom etc.
What is Source Port?
As you can see, Doom runs with Dosbox in Steam. And this is not very comfortable, because you can't play in openGL mode or with HD textures for example. So now I'll tell you how to handle this. But firstly, what is Source Port?

A Source Port is a fan-made program that allows you to play Doom on systems not originally supported (like XP, Vista or 7) or with new features and improvements, including 3D platforms support, OpenGL graphics, mouse look, higher resolutions etc.

There are many Doom Source Ports. All of them support all Doom games like Ultimate Doom, Doom 2, Final Doom and Master levels.

The most popular Source Ports for Doom are:
Game directory
If you go to the Steam\SteamApps\Common\Doom 2\ directory, you can see there three .bat files, such as:

  • doom2 + mouse.bat - starts Doom with mouse control
  • doom2.bat - this starts Doom without mouse control (classic controls)
  • testapp.bat - this one we won't modify

If you go to the Steam\SteamApps\Common\Doom 2\base directory, you can see there DosBox files, Doom2.exe, Doom2.wad etc.

There are 2 solutions to run Doom with any Source Port. Let's start.
Solution №1
Ok, fisrtly, you need to download any Source Port and extract it into:
Steam\SteamApps\Common\Doom 2\base

Then you must open doom2 + mouse.bat with notepad. In the file you will see this code:
.\base\dosbox -conf .\base\doom2m.conf -fullscreen -exit

In doom2.bat you will see this:
.\base\dosbox -conf .\base\doom2.conf -fullscreen -exit

So, then just delete all text in .bat file, which one you want to launch, paste this code (if you use Zandronum Source Port) and don't forget to save the file:

If you use Zdoom - paste this:

Or this one, if you use gzDoom:

That's all. Now you can launch Doom 2 with Zandronum or any other Source Port and enjoy the game with comfortable controls and OpenGL graphics.
Solution №2
Also, you can do another thing - after downloading Source Port, extract it into:

Steam uses Dosbox.exe to run Doom, so just delete it and then rename zandronum.exe, for example, to dosbox.exe. That's all.

Enjoy the game:)
Steam overlay
Sadly, you can enable steam overlay to take screenshots only in Ultimate Doom. But anyway, using, for example, Zandronum source port, you can play any .wad starting Ultimate Doom (Doom 2, TNT, Plutonia etc.).

To enable Steam overlay you need to use mine Solution №2 (only second, because the first one doesn't work with Ultimate Doom), then open ultimatem.conf file and find there these parameters:


You need to set them this way:


That's all. Don't forget to save the file :)
Cheat codes
There are cheats that you can use in all Doom games:

IDDQD - god mode
IDFA - gives you all weapons
IDKFA - gives you all weapons and keys
IDCHOPPERS - gives chainsaw
