Unlike the Liar Paradox, the Tarksi Undefinability Theorem sentence and
Gödel's 1931 Incompleteness Theorem sentence where the correct answer
to, is it true or false is neither, the Halting Problem counter-example
is provably non-halting.

typedef void (*ptr)();
int H(ptr p, ptr i); // simulating halt decider

// P does the opposite of whatever H decides
void P(ptr x)
{
int Halt_Status = H(x, x);
if (Halt_Status) // if H(P,P) reports that its input halts
HERE: goto HERE; // P loops and never halts
return; // else P halts
}

P specifies non-halting behavior to every simulating halt decider H
because P continues to call H to simulate it again until H aborts its
simulation of P.

*This is easily verified with my fully operational halt decider*

(b) Complete x86 emulator adapted from libx86emu to compile under Windows

You acknowledged that it does work...

typedef void (*ptr)();

// P does the opposite of whatever H decides
void P(ptr x)
{
int Halt_Status = H(x, x);
if (Halt_Status) // if H(P,P) reports that its input halts
HERE: goto HERE; // P loops and never halts
return; // else P halts
}

// This H(P,P) directly executes P(P) and is non-halting.
// and is an input to H
//
int H(ptr x, ptr y)
{
x(y);
}

int main() { P(P); } is not an input to H(P,P) thus is irrelevant to H
when it computes the mapping from its inputs...
