That's because they have to emulate 3 different processors at the same time, plus all the other shit with it. A Saturn emulator will actually take more processing power from a pc than a Dreamcast emulator. Same reason 32X & Mega CD emulation took longer cause the emulator had to emulate both the Mega Drive + either of the two, or in the cause of 32X CD games, all 3 machines. The best Saturn emu at the moment would be Satourne. It's making the best progress and it's the only Saturn emulator being updated.What about Saturn emulation? How can Dreamcast emulation be further along than Saturn emulation?!
The Dreamcast on the other hand, only has to have one processor to emulate plus the rest, not to mention all the DC hacking, the availability of dc developmental tools and advanced technology has helped speed up the emulation of the Dreamcast.
Which is good, cause from what I've heard, it's impossible or damn close to impossible..You mean a Saturn emulator for Dreamcast? I don't think my heart can take kind of excitement.
