I have a non merged set of the games, where each game is one zip with a bunch of files in them. But there seems to be so many versions of each game, do I need them all?
I have the exact same problem as OP.
Added a SNES game then deleted it and if I add it back now it says 0 games added. I have looked everywhere and cant fint any residue of the game.
The title in question is Final Fantasy VI.
