I'm trying to manage my Retropie FBA Rom. Some ROMs have region on title, some didn't have any region info.
If I do like this, everything works as expected:
BR US EU WORLD
But if I try to add NONE to the very ending, expecting to add those regionless ROMs to the database I end up with various ROM versions to the same game. 1 game 1 rom fail as if NONE (no region) was meaning ALL (all regions + NONE). Can you confirm this behavior?
