@karlos: i have only two conditions i need to acknowledge an amiga as such on any machine you throw on me.
1) amigaos should not be hosted on any foreign os especially if it is an commercial closed source. i would accept an abstraction over a kernel used to provide hardware support such as amithlon if i dont have to deal with it as a user but i prefer 68k native hardware that doesnt introduce jit precompile lag each time i start a 68k application, which applies as well to os4 as to winuae.
2) the backwards compatibility should be assured as far as possible, custom chipset inclusive. i know even back in the day it wasnt well taken care of, but that time there was still an evolving market, whereas today we mostly have to rely on 10-20 years old legacy.
