The Ultimate DOOM How to Run Custom Mods WADs on Linux Guide

How to download Crispy Doom

Of course, to run mods you need a source port. Here I will be using Crispy Doom because it is my prefered source port and it is (in my opinion) the easiest.

You can go to the snap store and look for crispy doom or you can type the following into the terminal:

 sudo apt install crispy-doom

How to run your main iWAD

To run your main iWAD file you will need to use the terminal. Shocking, I know.

 crispy-doom -iwad DOOM.WAD

This is the command I would use to get Ultimate Doom running in Crispy Doom. To chose what IWAD you want, you just need to change DOOM.WAD to whatever you choose.

Just to clarify, the code shown above only works if the IWAD is in your home directory. To use an IWAD that is, say, in your documents folder you would need to change DOOM.WAD to the directory, such as:

 crispy-doom -iwad Documents/DOOM.WAD

Remember that this is caps sensitive!

How to run a custom / modded WAD

In the previous section, we outlined getting the main IWAD running. Good. Now we need to get the mod running on top of that.

To do that, you must put in the following code:

 crispy-doom -iwad DOOM.WAD -file DTWID.wad

Anything after the -file part of the command will be your mod. I used DTWID.wad as an example, but you can use whatever you want. To use directories other than your home one, the same trick applies.

Conclusion

And thats it! I hope this helps anybody like me who keeps searching but can never find an answer. I think the same also applies to Chocolate Doom but I haven’t tried that out yet.
