Well, what exactly does it say? Are you aware of the fact that file paths are case sensitive in Linux?

its says: IWAD file /path to file/DOOM2.WAD not found. I'm not sure what "case sensitive" means tbh.

This means that doom2.wad is not the same as DOOM2.WAD and both may be separate files.

I see. I did experiment with renaming the file, but that also didnt work. So is he looking for doom2.wad or DOOM2.WAD?

If the path to your iwad contains spaces, you also need to surround it with .

Okay. Can you share the exact terminal output then?

And does the file /home/fredi/Doom_iwads/DOOM2.WAD exist? As mentioned before, upper case and lower case makes a difference.

100% it absolutely does. The WAD also works, as I checked it with a diferent sourceport. Could there be an issue with the way crispy searches for files on my computer perhaps? Putting the file in the root of my home directory also doesnt work. Neither did putting the file in the crispy directory.

Sorry if this seems like an inane request, but can you run ls -l /home/fredi/Doom_iwads and share the output?

Haha you really don't trust me it seems. Here's the output:

Someone removed the ability to access the file system: flathub/io.github.fabiangreffrath.Doom@5d0e935

A line like this needs to be added: https://github.com/flathub/org.chocolate_doom.ChocolateDoom/blob/c9575372cffade6d9d55240c853454d9066ef1d4/org.chocolate_doom.ChocolateDoom.yml#L14C5-L14C37

Until that's fixed, try adding --filesystem=/path/path:ro to the command line (more info).

I guess you can also copy the wad to the crispy directory under ~/.var/app/ ?

Oh, great that the problem got figured out! Could you perhaps post the entire command for crispy?

Tried already. Didn't work. And the WAD file itself works fine.

Quite the opposite, in fact! This problem seems kind of crazy so I knew there was no way you were making it up. 😄 I was thinking maybe a strange character got into the filename or perhaps the permissions got mangled.

Anyway, @ceski-1 to the rescue. (As usual!)

The flatpak works fine for me provided that the iwad file is located somewhere under ~/.var/app/io.github.fabiangreffrath.Doom.

For example:
flatpak run io.github.fabiangreffrath.Doom -iwad ~/.var/app/io.github.fabiangreffrath.Doom/DOOM2.WAD

For example: flatpak run io.github.fabiangreffrath.Doom -iwad ~/.var/app/io.github.fabiangreffrath.Doom/DOOM2.WAD

That's probably a more secure approach than exposing other parts of the file system to the flatpak. Maybe someone can update the manifest to be more convenient.

This also works with the above but I'm not sure what the best practice is: flatpak run --persist=. io.github.fabiangreffrath.Doom

I know next to nothing about flatpak, but could you add a wad directory to the data folder and then set DOOMWADPATH to that directory and then inject it into flatpak environment? Then the user could place their wads in that folder and call them by their bare filenames.

I just wanted to say that it works now! Also do I have to put in the filesystem command everytime I wanna run Crispy?

@Cleetu5 Could you confirm that if you put DOOM2.WAD in the ~/.var/app/io.github.fabiangreffrath.Doom/ directory and then call crispy-doom using flatpak run io.github.fabiangreffrath.Doom -iwad ~/.var/app/io.github.fabiangreffrath.Doom/DOOM2.WAD that it does not load for you?

Manually setting DOOMWADPATH over Flatseal and then copying the WAD files to the respective directory within the sandbox seems to work. It's important to keep in mind that Flatpak does not replace $HOME by the root of the sandbox namespace itself, but it exposes the respective .var subdirectory, i.e., DOOMWADPATH should be set according to the actual user home directory. DOOMWADPATH=/home/foobar/.var/app/io.github.fabiangreffrath.Doom/data/wads should do it. Don't forget to replace /home/foobar with your own home directory path. $HOME doesn't work as Flatpak (nor Flatseal) does bash-like string replacement.

I ran into the same issue trying to load Crispy Doom on the Steam Deck. The quoted solution was enough to get it going. Thanks.
