Yes. I would recommend a dual boot system with AOS3.x to run WHDLoad.

On the other hand if is possible to use memory virtualization feature under OS4 to fake the memory map of classic system, then maybe UAE can run on top OS4 JIT emulation, just imagine the speed benefit, if you have stock 68020 CPU at 12 mhz, whit OS4 JIT most likely get 680X0 whit 50+ Mhz under emulation even on slow PowerPC 604, 200 Mhz PowerUP card.

This would be something to improve UAE. Not appropriate for WHDLoad because it also needs the cia/custom chips.

There is no way that you can actually use the 68k anymore. The boot loader patches a rom routine that puts the CPU into a HALT so it doesn't use memory cycles.

In that case there will be no WHDLoad for AOS4. A full emulation using UAE must be used instead.

The current WHDLoad cannot work under AOS4 because it wont work inside 68k emulation. It takes over the operating system...

Technically it should be possible because the hardware is present (CSPPC/BlizzardPPC only).

The question is if AOS4 offers a way to use the 68k cpu. As long as I have no AOS4 I cannot do any investigations. We will see what the future brings.
