Unable to play ports from NFS

[klein1jo]

Posted this issue to the forum 2 years ago; https://retropie.org.uk/forum/topic/32543/ports-not-working-all-other-roms-working/9. Still not resolution. I'm running the latest RetroPie image on a RPi 4. I was previously using a RPi 3. I have updated the Pi using the update option in retropie_script.sh.

Ports and only ports will not run from NFS. Tested with both Doom and Duke Nukem 3D. See output below. Error is 'not a directory', but as you can see I can navigate there a list the files.

My latest test, I plugged a USB drive into my RPi, copied the ports to it so it was a local block device, and mounted it on /home/pi/RetroPie/roms/ports. Ports worked just fine doing that.
