For a long time, we didn't knew if it is possible to emulate 16 bit systems like Genesis or SNES on Saturn. Well, now it seems we have certainty for the SNES:
On special request, I started porting snes9x to SEGA Saturn. The hardest thing involved was to meet the RAM requirements and so the emu requires a 4MB RAM cart.
The emulator already features loading from CD and frameskip setting. Unlike these shots from SSF, the gfx is not yet that correct on real hardware.
The future of this project is undetermined, it's on hold currently.
