Do not download the ZIP file as it doesn't contain the required files from shared-modules repository.
Instead, do:

git clone --recurse-submodules https://github.com/dgcampea/desmume-flatpak.git

By default, this flatpak only allows reading from HOME and saving to XDG-VIDEOS and XDG-MUSIC directories.
If you want to save/read from other locations:

flatpak override org.desmume.DeSmuME --filesystem=host
