@Bond697, you did confirm that there is no LCRNG in sample0519, which indicates that most likely most, if not all data for the PKM is in IWRAM. This would include species, PID, moves, etc. Which makes sense since for example with the 5th anniversary eggs, there is a random pokemon chosen, with a % chance of a shiny pichu. They probably set the data in IWRAM, and then the slave simply copies it via PKM format. That means sample0519 in both of those events are interchangeable/universal.
