In a lot of ways I think AROS needs classic Amiga and classic Amiga needs AROS. I'd be happier if if in some way classic Amiga were emulated.
To Emulate a real Amiga on "AROS 64" you would need:
A real copy of OS 3.x and/or it's kickstart or a AOS3.x compatible AROS M68k build. I do not think it's smart to rely on copyrighted material for a open source OS to function "properly". So i take it you want AROS M68k too? :-D
A lot of people seem to expect 2 things: For it to happen overnight and for someone else to do it.
People usually pay for Hardware so it's no problem to wait for someone else to do it. On the software side - if everybody (maybe 1000 people) would give 10€ to the Aros Kickstart bounty's the one we expect to do it for us would get 10.000€ for his effort...
