Decreasing compatiblitiy of OS4 a good thing?

@LiveForIt

On AROS there is a experimental version with SMP support. As I understand it the concept is one core runs the system processes, apps are automatically started on other cores or can be started on a own core. Advantage, system is more stable and expeciaslly more resposnsive

But this of course needs changes in exec that affect compatbility. No problem if your software base is limited and mostly sources available and adaptable, a problem if most software is closed and cannot be recompiled. The same is true for 68k.

Another topic is migration to 64bit. You have software that is 32bit and cannot be reompiled. Solution is a runtime where 32bit software works on 64bit system..

68k can be solved by UAE of course, for example Amiberry.

So in short you need to modernize to drop compatibility to the old 68k amigaos and also to the existing PPC base and solve it by runtime/VM for PPC software (QEMU?), perhaps runtime for closed 32bit software, integration of 68k using UAE (as transparent as possible). Petunia will no longer work
