sega saturn emulator

hey guys im kinda new to the sega saturn emulation scene...ive been into genesis, snes, neogeo, and nes for sometime...i i was wondering..if there was a saturn emulator that would actually work under windows xp professional..if tried a few..i was trying to play lunar sss...but none of the emulators worked..can i get some really appreciate it
the saturn is a complex machine.and as far as i know the emulators only just sound and at about 4 frames per will probebly be a long time before any decent emulator emerges.
