Yeah, I agree. We went off on a different conversation, there.
I really don't understand when people feel they need every single version of every single emulated game in their cabinet. No one is going to play all of the hundreds of Amcoe games. No one. No one is going to play all 20 or so SF2 clones & bootlegs often enough that they need them each in the menu.
This whole sense that you must have everything... that's the cause of a lot of trouble in the world outside of emulation, and the cause of a lot of trouble inside the world of emulation. Worry about what you need, and nothing else. Better yet, worry about what you legally own, and nothing else.
If OP has the full CHD set, even for games they'll NEVER play, I can understand where the desire to centralize originates. Takes a long while to pull down enough of a CHD over a network to get started in an emulator, and folks that have every single game in their menu seem to do so because they can't just pick a game and play it, alone, for a few days.
But, yes. If you can't fit everything you want on a computer in the cabinet, maybe it's time to really survey what you need and what you don't. You most definitely do not need everything.
