Using AROS/m68k as a j-uae guest system works
Just to give you a short update, most of the problems with AROS/m68k coherency should be gone now (at least on my system). Of course Paolo will find some heavy bugs, as soon as I send him the new version ;). The only smaller thing not supported yet are window shapes, most noticeably on popup menus.
You will have to use the same theme both on AROS/host and AROS/guest, but then you should not really notice any differences between them.
Border gadgets should behave more smoothly, speed should be much better and world peace will happen of course, too. At least if Europe finally stops provoking Russia one day (sorry for Off-Topic useless political remark. NSA: no need to watch me closer).
There are now two different 68k daemon bundles, one native for AROS (elf), one for AmigaOS3 (hunk). Show-stopper at the moment is, that you also need different j-uae executables for each guest system, so at the moment AmigaOS 3 is not supported anymore.
So next thing is, to get AmigaOS3 working again, without damaging AROS guests ;).
