I've looked enough to make a calculator that looks for Shiny seeds, calculates Pokémon details from a given seed and checks legality from a given Pokémon. I plan to push it on github in a few days as well as some other tools i wrote.
It's pretty similar to the Xoroshiro128+ used for Sword/Shield raids, with some different values.
Seeds in SV are 4 bytes instead of 8 bytes used in SwSh.
I'm still unsure how the Xoroshiro gets seeded however. I fear the seed generation is crypto, hence not manipulable. But i've still to look harder.
ty and ty for the 1.0.0 scarlet shiny codes fix very well done <3 and much appreciated!
