Hi

thanks for bisecting the issue ; unfortunately, if it's a 68030 cycle 
accuracy problem, there's not much that can be done at the moment.
even if winuae improved a lot for 68020/030 (mmu, bus/address errors, 
....), cycles emulation is not accurate enough yet. In some case it will 
be better than older Hatari version, in some other cases it will be worse.
