I saw that 'Hide all games' button in the 'Game Lists' tab too, but you're still left with possibly hundreds of ROMs that need to be manually installed in the Destination list. Is there a way to list all working ROMs that are actually =in= your ROMs folder?
So, what's the solution for loading all working/installed ROMs into the playlist?
Mala Gamelist Editor 1.1 beta could use a filter "Display only working ROMs" in the Gamelist dropdown menu to solve this, which would expedite the 'Source' -> -> -> 'Destination' process.
And a pony.
Actually, I think MaLa comes with a pegasus, so forget the 'pony' feature.
