Question about legality in this jirachis from channel

[Mechrow]

Hi,
First of all, english is no my first languaje so i apologize for any speeling or grammatical error.

I was trying to make some jirachi using this method 

But i'm very impatient and i don't want to wait for the script to finish, so i tried diferent methods to make the whole process faster, as a result i found that "0x[code]" is the actual seed (i think) and started to experiment, resulting in 5 jirachis that pkhex marks as legal but i have doubts.

The process whas this:
1. Ii use this Jirachi, Timid shiny square 0IVs attack

I copied the PID and search in "PID to IVs" and use this seed instead of the script (why this and not the other?, i dont know, i'm not very smart)

2. In this part before recive the jirachi
 

Pasted the seed from pokefinder to memory location "8033d888" just like the normal tutorial


Received the Jirachi

From pokehex


This was all, doit 4 more times and all was marked legal

All the programs was
-Dolphin 2409-254
-Pokefinder 4.2.1
-pkhex 20240727

I know that modify the RAM to make this Jirachis has a high porcentaje of being ilegal
