At the moment ZSNES can load ROMS directly off a network path (not a mapped network drive) eg.
\\otherpc\roms\snes
But it doesn't save the setting (you must input it manually, of course). I'm guessing this would be a relatively easy fix. Other emulators I've tried are fine with network paths.

I think there may be some more general path bugs that may include both network paths as well as relative (but local) paths. At least in Windows, maybe. I've had problems with savestates and saverams with relative paths.
