Sega Saturn
For a long time, way back at the beginning of emulation, Saturn emulation was deemed close to impossible (or at least really hard). Good thing those days are behind us now. SSF has been in development for a few years now, and has come a long way from it's beginnings. It's still not perfect yet, but runs many games full speed now on higher-end systems.

The webpage and readme are written in Japanese, but all of the menus in the emulator are in English, so it's fairly easy to figure the program out (of course, assuming you understand English). Grab it at the link below
