[Linux/Ubuntu] Can't pass any CLI arguments to flatpak

[itsonlyMiRE]

I'm on Ubuntu and running desmume with flatpak run org.desmume.DeSmuME. Trying to add any flags/arguments after this always results in Unknown option --[option here].

Also, when I try launching a game thru CLI with flatpak run org.desmume.DeSmuME "/path/to/nds/file.nds", the desmume window opens with a dialog box saying "Unable to load: /path/to/nds/file.nds".

Let me know if more info needed.

EDIT: launching from CLI worked after I built from source. Why is the flatpak version the publicly advertised Linux version if it doesn't work properly?

Sounds like a question for whoever added flatpak scripts, @linkmauve

I am also having this issue. The only workaround is opening DeSmuME, then going to File->Open and then manually finding the .nds but that starts to get tedious when I have to do it for every single game.

found the solution to the.
in the flatpack finish-args options, --filesystem=host:ro needs to be added.
1 line fix. made a pr on the flathub repository to fix it.

this issue can be closed now
