Every C programmer that knows what an x86 emulator is knows that when H0
emulates the machine language of Infinite_Loop, Infinite_Recursion, and
DDD that it must abort these emulations so that itself can terminate
normally.

The H0 case is very different. For H0 there is indeed a false assumption, as you mentioned. Here H0 needs to simulate itself, but the simulation is never able to reach the final state of the simulated self. The abort is always one cycle too early, so that the simulating H0 misses the abort. Therefore this results in a false negative.
(Note that H0 should process its input, which includes the H0 that aborts, not a non-input with an H that does not abort.)

This results in a impossible dilemma for the programmer. It he creates a H that does not abort, it will not terminate.

When every input that must be aborted is construed as non-halting
then the input to H0(DDD) is correctly construed as non-halting.

Since your "Needing to abort" is NOT the same as halting, all you are doing is admitting that your whole logic system is based on the principle that LIES ARE OK.

You are simply too ignorant to understand this.

Again, how can you claim a "Correct Simulation" by the exact definition of the x86 instruction set, when you omit the call H instruction, and then "jump" to an addres that was never jumped to at any point later in the program.

 But the question isn't DDD correctly simulated by H0, but does DDD itself, when run halt.
 

The proof that you are wrong is over your head.

You have been stuck on the wrong question for ages, because you just belive your own lies, and think you are allowed to change the definitions of terms.
 

No that is not it. I have known the truth for two
decades and am just now expressing it in words.
If the halting problem is correct then truth itself
is broken. Since truth itself cannot be broken then
the halting problem cannot be correct.
This is all anchored in the details of truthmaker
maximalism.

Do that just makes you a LIAR, and so that is what you are.
 

*Calling me a liar may get you sent to actual Hell*
That you have a religious conviction that I am incorrect
is a bias that prevents you from trying to actually
understand what I am saying.
Perhaps you are too ignorant to understand that bias
is a systematic error.
