Damned Liar !!!
I have told you too many times that correct simulation
is simply obeying the semantics of the 86 language for
whatever the x86 input finite string specifies.

If the x86 string tells the computer to catch on fire and
the computer catches on fire then this proves that the
emulation was correct.
