Dropbox saved games

I use a Windows PC that is hooked up to my TV for my SNES gaming.  It is faster than my MK802, but my MK802 does have reasonable performance.  It got me thinking, though.  What if I'm on the road and I want to play an SNES game?  My MK802 could handle it, but I wouldn't have my saved games.  That is when it came to me.  I could point my emulators to save the game data to my Dropbox account!

On Windows, I use Zsnes.  That is part of the reason for the performance instead in Windows.  Zsnes is a lot faster than Snes9x, but it is partially written in x86 assembly.  This means it cannot be ported to Android, who's main architecture is ARM.  Just about all the SNES emulators for Android are ports of SNES9x.  The saved game data is in the same format, though.  They write the raw data that the game writes to EEPROM.

I also came up with the idea that I can share the SavedGames folder in my Dropbox with a friend that also has an emulator running.  He currently uses Zsnes in Linux.  Then, when I go over to his place to play video games, we can continue with the progress that each of us has made.  I brought this idea up to him and he was super excited.  

At this point, this is all theoritical.  I don't know if this will work.  I don't know if the emulators keep the file handle to the EEPROM data open.  I don't know when Dropbox will detect the change.  Will it upload after every save point in the game, or once I exit the emulator?  I  will do some testing in the coming weeks to figure these details out.
