>How many ROMs do you have
Probably around 80,000. I have 24,364 games individual games as far as I can tell, and most of them have 2-5 region options.
>How do you organize them
By platform. I thought about splitting the platforms themselves by region, so I can have NES and Famicom, TG16 and PCE, etc., but decided against it.
>What's your setup to play them
Other than real hardware, I use Launchbox, primarily with Retroarch for most things.
I have the platform list sorted by manufacturer and then release dates, so if I want to play SNES, it's between Game Boy and Satellaview. I also have playlists for individual series that are sorted by release dates, and I've made some categories where you select Nintendo, Sega, NEC, SNK, or Sony, and it lists all their platforms exclusively.
