My work got buried by an ignorant forum admin at first, but I am still going. He doesn’t know the Zodiac very well. Neither do I, but better than him apparently. He has been following this case for like 30 years, far longer than me. So that is pretty strange to not be able to put 2 and 2 together. Welcome to the internet.

I’m not Faycal 2.0, I actually solved this code the right way. He used weird steps that he liked and seemed cool. I used the steps the Zodiac instructed with this cipher, and nothing more.

So yeah another day and I am still here, still working on version 3 of my paper, will submit it to other journals, translate it into other languages, port the code to Javascript, make my videos, ect ect.
It ain’t over until the landmark is scanned. Then I win.

This became a battle rather than a collaborative search for truth due to censorship, bad debunks, and a wall of silence from experts.
It goes back to my previous opinion that people made Z32 much more difficult than it had to be. It could have been solved decades ago as well. But they wouldn’t have had Google Maps. Still solvable though, the landmark David Stampher found in December 2025 would still be in the same place regardless.

But yes, a manual solver was never going to crack Z32. Their method wouldn’t prove they tested all of the other possibilities, which is a weak method.
It is why @shaqmeister is so offended by the codebase, and the Haversine formula usage. These manual solvers hate to see code win the game, but that is what happened, and what had to happen.

Guaranteed Zodiac internet forum users will never know the feeling of cracking the Mount Diablo Code.
But I know the feeling, and it is unlike anything else.

Sure I am biased, but one is an exhaustive search with a smart ranking step, the other is subjective mental gymnastics that sounds good for a documentary or forum post.

I am biased because I found the landmark, that is true.

Just reading others bad theories on Z32 while I wait around for the scan.
“Why would these codes and/or unsolved problems be significant when the 408 and the 340 weren’t?”
Love this one, it is common. They think because the other two solved ciphers didn’t lead anywhere, that this one is meaningless. We will see about that theory.

I’d say the “Z32 leads nowhere” rumor is the dominant theory on this cipher. Not sure which expert perpetuated that myth, but I am dealing with it now.

They tell themselves this story because they weren’t able to solve the cipher and find the landmark. By saying it leads nowhere, they have convinced themselves they solved Z32, by saying it is unsolvable and a waste of time (because it leads nowhere, according to them). The irony.
