WadFusion — simple IWAD merge utility

[Owlet VII]

WadFusion is an active fork of JPL's discontinued WadSmoosh—a tool for merging all of the official classic DOOM games and expansions into one IPK3.

The list of new features added to the fork includes:

• Support for Legacy of Rust.
• Support for the Master Levels rejects.
• Support for masterlevels.wad from the DOOM + DOOM II release.
• Support for the alternate MP3 soundtracks of SIGIL / SIGIL II, with options to switch between MIDI and MP3 music on the fly.
• Support for Andrew Hulshult's IDKFA soundtrack from the DOOM + DOOM II release, which can also be switched on and off on the fly.
• More compatibility options.
• Super ultra-widescreen support.
• A "Full Run" mode that plays all episodes in succession.
• Optional introduction screens with story text from the manuals.
• Many smaller enhancements and bug fixes.

A full list of changes is available in the changelog. The readme contains a full list of supported WADs and and instructions on how to use the tool.

Much like the original WadSmoosh, I do not intend to add support for any unofficial WADs. Some users have already went ahead and started doing that on their own.


WadFusion is a Python 3 script, but a Windows executable is also provided with releases.

You should also add support for Heretic, Hexen and Deathkings of the Dark Citadel. Take advantage of the fact that they released the remaster of those games.

Those games won't work with Doom, if that's what you're asking.

Those games won't work with Doom, if that's what you're asking.

But it could serve to merge Heretic with Hexen and their respective addons and thus maintain continuous progress between those games without the need to start from scratch every time. Especially if you play mods like Wrath of Cronos or the Serpent Resurrection RPG Mod.

You might want to check out HXDD for that.

So as of now is this tool not working? I tried it out the other day and the new .ipk3 wouldn't load in one of the newest beta versions of GZDoom.

[Owlet VII]

The current stable version of WadFusion works with the current stable version of GZDoom. If you wish to use Fusion with the GZDoom dev builds, you will also need to use the dev builds of Fusion.

Do note though that GZDoom's recent implementation of tooltips appears to have broken long episode menus, so either downgrade to a dev build from before those changes, or wait for the issue to be fixed.
EDIT: This issue has been fixed in UZDoom.

I've asked the author of WadSmoosh to support loading IWADs from a user specified directory rather then from the application directory, but he rejected the idea. Can you please add this in your fork? This would make using the tool much more convenient. Thanks!

[Owlet VII]

That is an excellent suggestion. I'll add a command line option to specify a source directory, and I'll also look into adding an option for the script to read from a text file with a list of directory paths (or specific files) that the user could set for it to search in.

Hello! I have used wadfusion and i like it a lot. I use it with Delta touch and it has been great until the uzdoom was added to Delta touch. I noticed that uzdoom does not support wadfusion when using Delta and i have been told that the maker of wadfusion needs to add support for it. Hopefully this can be fixed. I can send error log if needed.

[Owlet VII]

I don't have Delta Touch and I don't support it, but I can take a look at the log. I suspect that the issue here is that Delta Touch's UZDoom is a dev build, so you'll need to generate the Fusion IPK3 with the current WadFusion dev build, as I explained a few posts ago in this topic.

My problem here is that the wadfusion dev build is for linux and does not have windows support. Or maybe i'm mistaken? But here's the log

[Owlet VII]

Okay, yeah, that version is built from a UZDoom dev build.
WadFusion dev builds aren't just for Linux, wadfusion.py is a Python script, you should be able to run it on any system with it installed.

There is something wrong with the dev build wadfusion. Everytime i make a fusion i get this error. And i don't use shareware version.

This same file was tested on pc and it also crashes but it gives these errors. Any idea what they are and are they fixable?
