Maybe I have incorrectly express myself. :)
I should have said "there is no software yet" rather than "there is
no way".
JIT is a nice idea, but for an MMU emulation, even with JIT, it is
just too much ressources consuming, really to much. By the way, I took
the example of ARAnyM which emulates more than a single processor,
but a graphic card, system buses, and some other peripherals. Hence,
my remark was misplaced. ;)
Cheers.
