Would this work? Could be a useful idea.

I am a big RPG fan, love them. That said, I have a TV in multiple rooms that I would like to play on. What if I had 2 computers, and installed Launchbox onto both of them in different rooms, and stored and installed all of my emulator stuff in Dropbox? In theory, it should work just fine, my saves would all be in drop box for either computer. The only potential drawback is some of those huge games load times from drop box. However, to remedy that, couldn't I just set up all of my memory cards in drop box, and install all of the actual emu stuff and roms on each computer separately?

Yea, this can be done. However, the best solution I've seen is software related. I've seen users use software to keep they're LaunchBox install, games and saves backed up to several PC's. They're generally free and work great. The only problem I see is if you can't store your save states or memory card files outside of where the games are kept or outside a dedicated location. For something like PCSX2 where you can change the specific location of your memory card files, this works, but not for save states. If you made your Emulator folder a Dropbox folder, and used Dropbox to sync to multiple PC's then that could work. The files are still stored on your PC, their folder structures are kept in tact, and you should be able to access it anywhere. Just make sure you make your Dropbox account private, as in the file are kept private and not automatically view able to who ever can search for them.
