Should yes, but it remains to see if they will run at all. Currently even OS3.9 doesn't work well, but that should be fixed quickly one can hope. The thing with Macintosh emulators is that the CPU is not emulated in those.
What is wrong with OS 3.9? You said even the actual OS 3.9 does not work well, why?
Side note: In the very very very distance between Jupiter and Earth future, if the SAGA does become reality then all Amiga specs will be 100% the same. It will be who ever choose an Amiga model it will be for the sole reason of the flavor he likes and favorite style more than anything else. AGAIN IF THIS VERY between Earth and Jupiter distance future does become reality then I am content with my favorite flavored A500. Others will be A600, while others be will be A1200 and others will be A4000.
THE VERY CONCEPT excites me!
