It is unreachable by the Halting Problem counter-example

If is was true that it is not a faithful simulation
then you would be able to show exactly what sequence
of instructions would be a faithful simulation.
The sequence executed by HHH1, as you are on record as admitting is correct:
What exact sequence of the following machine addresses
of DD emulated by HHH causes DD to reach its own
final halt state at machine address [00002155]
When this sequence is required to conform to the
rules of the x86 language?
_DD()
[00002133] 55 push ebp ; housekeeping
[00002134] 8bec mov ebp,esp ; housekeeping
[00002136] 51 push ecx ; make space for local
[00002137] 6833210000 push 00002133 ; push DD
[0000213c] e882f4ffff call 000015c3 ; call HHH(DD)
