Thank you for the offer, very kind. It sounds a bit beyond my skill level though. For now, I think I'll just keep my MAME library on an external drive and plug it in when I want to play something

Yeah that makes sense, and maybe I could look into making my own smaller non-merged set down the road. As an alternative, how does LaunchBox handle ROMs on removable media? Would LaunchBox throw a bunch of errors if it opens and the MAME set is missing? And would it welcome the files back into the fold if I reconnected the drive?

Thank you for the quick response. What about moving the full set into my LaunchBox folder, importing the full set with the non-casino, non-handheld, etc. restrictions, and then running some kind of clean up to delete those files from my LaunchBox folder which are not in my library? Is that possible? Edit: Oh, I see what you're saying. The Split set is already a pared down version in a way, and picking and choosing could break certain games if I understand correctly

I have the full 60 GB set of MAME roms on an external HDD. I'd like to be able to copy just the parents to my LaunchBox folder while skipping the casino games, fruit games, handheld games, etc. so that I'm not wasting a bunch of space on my internal drive. Is this possible in 8.6 premium? I couldn't find an option in the MAME full set import feature to copy to library. Thanks!
