apologies for the late reply ( EDIT: Got it working by unchecking "Remove Quotes" box, no idea why that caused it. Tested by re-checking box, none of the duckstation games with a hyphen in the file name worked again.
Games with " - " in the emulators files not working (example: CV - SOTN, Tenchu 2 - birth of the stealth assassins and persona 2 - eternal punishment)
These games bring up an error: "unknown parameter: - "
All other games are working.
apologies if its an easy fix im not seeing.
