Yabause is a Sega Saturn emulator under GNU GPL. It currently runs on FreeBSD, GNU/Linux, Mac OS X and Windows.

Remember, remember, the 5th of November, for it’s the day of a new Yabause release! This release includes the long awaited save state support(linux and windows ports for now, sorry) and lots of bug fixes. Anyways, check it out.

Edit: One thing I forgot to mention: Aside from the windows binary and the source the other ports will follow this week. Guill moved to a new house(and has no internet) and I’ve been having trouble with some of the builds. Sorry about that.
