Do you ignore all of Bernd's AfA news posts? Where he compiles parts of AROS to replace parts of AmigaOS on 68k hardware?
The AROS developers take great pains to ensure that when compiled for the 68k CPU AROS is binary compatible with AmigaOS... Try can only do this because AROS is an OS that reimplements all of AmigaOS's features and structures. This is exactly the same as MOS and AOS4, except they (AFAIK) only compile for the PPC, AROS an compile on multiple architectures.
@Piru AROS's UAE integration features a Unity mode (that is kind of the point), bit the idea is that we can get it much tighter as AROS and AmigaOS are so similar and we can modify both UAE and AROS to work together... End result, 68k apps running seamlessly in a x86/PPC AROS environment
Please spend more time on the AROS Dev list, there are people working on a complete Amiga port of AROS, I'm sure you could offer advice
