"Why are save states not compatible across DSP engines?"
When I read this, I actually thought it was a fairly interesting question. So I brought it up on the IRC and got this response:
"DSP LLE saves registers, where as DSP HLE has no idea what values they're supposed to have."
The answer is simply that DSP LLE has more/different information to save than DSP HLE, thus if you were to load a savestate from a different DSP engine, bad things would happen.
