PID Method for the berry fix shiny zigzagoon?

[BPSpike]

Anyone knows what's the correct PID method or IV spread that was used for this pokemon? I'm mainly curious as many the ones floating around on the pokecheck GTS return a valid gen 3 egg PID there, and a hacked berry glitch zigzagoon warning on the old sabresite's legal.exe (which I know it's outdated, but it just seems wierd).

Sabresite built berry fix zigzagoon checks into his program; legal spreads shouldn't say hacked.

I know Sabresite built in the checks into his program in the 53-xx or 54-xx. What I don't understand is what method is used to generate the legal ones and what's exactly the difference when the only change in some of them is just the... and IV/spread. Thanks for clarifying that just in case .

Yay, found out what exactly was the difference between those zigzagoons passing the legal.exe check and the ones which weren't making it. The valid PID is generated on the Gamecube with a different PID method than the other (invalid and illegal) ones. Somehow Pokecheck isn't recognizing this difference.

But at least now I can rest at ease knowing what method they used
