WadSmoosh - simple IWAD merge utility
WadSmoosh merges your provided Ultimate Doom, Doom 2, Master Levels, No Rest for the Living, and Final Doom data into a single IWAD file that can be played in GZDoom, with each game as its own entry in the episode list. This makes it very convenient to play all of classic Doom's official releases without relaunching the game with different settings.
It's fine if you don't have all of the Doom games, eg you have Doom 2 but not Final Doom - WadSmoosh will package up everything it can find.
If you're not a Doom expert and just bought these games off Steam etc, see the Absolute Beginner's Guide section below.

source_wads/ subfolder, then run WadSmoosh. A log will appear showing progress and any errors that arise.

WadSmoosh will create a new file called
doom_complete.pk3 with all the game content in it. You can run this in GZDoom with
-iwad doom_complete.pk3 at the command line, or even rename it to
doom2.wad and run without any command line needed. GZDoom 2.4 and later will recognize the
doom_complete.pk3 file as a valid IWAD without any name change needed.
If you've extracted the No Rest for the Living addon episode for Doom 2 from Doom 3: BFG Edition or the PSN or XBLA versions, make sure it's named

In rare cases, you may need to uncheck the
source_wads/ folder's read-only status.
Advanced users can edit
wadsmoosh_data.py to customize how and what WadSmoosh extracts. This file is Python code, read by the main program at runtime, so no recompile is required. You can also customize the ordering of the Master Levels in
