The next release of DreamSNES is said to be full speed. More optimizations must've been done.
I won't believe it until I see it.
If it's true though... it's
ABOUT DAMN TIME they learned some real SH4 ASM.
As for the Saturn, I was also thinking SNES, Genesis, SegaCD and even 32X emulation may be possible. The 32X emulation seems possible as the Saturn already has twin SH2 processors. Are those SH2s clocked above those of the 32X or at the same speed?
SNES and Genesis would be very painful to emulate on Saturn. SNES especially. I've been checking things out and unfortunately, not as much as I'd hoped can be offloaded to the graphics processors (IIRC, Mode 7 is surprisingly compatible with VDP2 but other than that, can't do a whole lot). Interestingly enough, though, the CPU and sound could very easily be done - sound by the 68k and CPU by one SH2.
A lot of Genesis can be done, though. Genny's main processor is a 68k, and Saturn has a (higher-clocked!) 68k in it - but it isn't quite the same processor, and the 68k is still needed to access the Saturn's sound hardware, so it isn't as simple as one would hope.
And 32X is totally out of the question. The SH2's in 32X are slower than Saturn's, which means you'd need something to control timing (say, the 68k...), but then you have nothing to do graphics or sound, which are both totally different in Saturn.
And SegaCD is also impossible. It has an additional 68k over Genesis (which is already very taxing).
