Greetings. I plan on have a Platform called Top 50 Arcade Games. It'll basically be a subset of my Arcade Platform [my imported romset]. When I boot into Bigbox I want it nice and simple and just have the two options...the two Platforms This is not as easy as I hoped...not that I'm complaining as this post is just to highlight my way around this. I just created a second instance of MAME using a different romset version and imported these roms into my Top 50 Platform. I couldn't see a way using Playlists to create the second Platform in such a way that it left the two Platform options only. Anyway, I'm big into the Bigbox now.
