If I recall correct, the 060 is 32-bit pure and hardware emulates <32-bit by simply stripping the communication since it would take more resources to do it "the right way" (and it wouldn't shave any cycles anyway). As others pointed out: modifying CF to do this is not a viable option. So (finally) my question is: will doing this with JIT have a notable impact on performance?

By "notable" I don't mean a reduction of a vanishing factor 4 in the scope of a x1400 or x140 gain.

A wild stab in the dark: because it needs to emulate everything all the time - as opposed to the CF who can use emu when it needs to?

But then again I don't know what I'm talking about when it comes to JIT and CF. -Less than the thread-average anyway.

You really got him there HenryCase; no Amiga user would ever recall any of the weeks last 57 gurus and which of the 3 OS versions he used at the time :-)
