Ah ok, I see. So this feature is maybe coming somewhere down the line then ?
I'm relatively new to Launchbox, but I thought you could make custom platforms as well.
So that got me thinking, maybe you could create a second Mame platform under a different name with only the games you want and then you can export that ?
Or isn't that possible ?
Edit : I've installed a 3rd Launchbox and isntead of using the import Full mame set option, I've just imported the roms, which I first copied into a separate folder.
