The two are quite different. Win3.1/NT/95 were all 32-bit systems, so they had the benefit of being able to use VM86 to do 90% of the work for them. In long mode (64-bit mode), vm86 no longer exists, so this approach cannot be used.

Thanks for the clear response, I hadn't thought about that. I'd forgotten about the differences between 32bit and 64bit mode on modern CPUs, and that dosemu and dosbox aren't the same thing.
