Getting the BFG editions of Doom 1 and 2 working on modern source ports
This guide shows how to make the BFG editions of Doom 1 and 2 work with your favorite source port.
Getting the versions of Doom 1 and 2 included with Doom 3 BFG to work with modern Doom source ports is easy. Here's a quick guide to get the BFG editions of Doom 1 and 2 working with your favorite source port.
ZDoom and GZDoom
First, download the latest version of GZDoom at or ZDoom at Then, unzip the file you downloaded wherever you want. After that, start the game and it should show the BFG editions of Doom 1 and 2 for play! Easy.
Other ports
Before we start, I recommend getting the latest version of your source port of choice. Earlier versions do not have support for the BFG editions of Doom 1 and 2.

First, go to your base Doom 3 BFG Edition folder (C:\\Program Files (x86)\steam\steamapps\common/doom 3 bfg edition). When you're there, look for the “base” folder and open it. From there, look for “DOOM.WAD” or “DOOM2.WAD”. Copy whichever ones you want.

Now, go to the folder where your source port of choice is. After getting there, paste the files you copied into the folder that has your source port of choice. Now, start the game and it'll work just fine.
Doom 2 issues
The BFG version of Doom 2 has a missing piece of code that makes it impossible to run on some source port. Most modern ports (GZDoom, Doomsday, Odamex, Zdaemon, Chocolate Doom) have ways to get around this, but with some, like (prBoom), you'll need to fix it manually.

Doing this is easy. Go to {LINK REMOVED} and download the file. Unzip it.

Now, do the steps above. Now, before you start the game, drag the “d2ttlepic.wad” file to the engine .exe and drop it. Start the game, and it should work just fine.

You can also download Classic RBDoom3 BFG (search it on google).
Which allow you to use classic DOOM parameters, load mods that require DEUSF or DeHackeD/BEX and input cheat codes without the console (only on Doom & Doom2)

oh & before i forget: readme is in english but here the text: Use the command line to apply the included patch files to your DOOM.WAD and DOOM2.WAD files using bspatch.exe.

Type the following(*) and run it to create the original 1.9 version IWADs from the BFG version IWADs:

bspatch udoombfg.wad doom.wad bfg2udoom.pat
bspatch doom2bfg.wad doom2.wad bfg2doom2.pat

(*)Maybe -depending on the real name of your .wad files-
you have to rename them accordingly beforehand. This is the required synthax:
bspatch (yourexisting BFG-DOOM-WAD) (nameofthedoomwadthatwillbecreated) (patchtobeapplied)

so, well, the only problem is this site is in german language but i try explain, go on this site scroll down to the bottom & down ther is a word in fat blue called 'hier' (means here in english) then the download happens automatically : & with this versions then it should be possible to play on every port, i hope it helps anyways a bit

@iqdog - in the options for doom 1 and doom 2 turn on "Enable Gamepad" - I believe its the same for Doom 3
