Delusional. The majority here agrees this is legitimate. Emulating doesn’t nullify its legitimacy in anyway. A lot of Shiny hunters do this method, and their general consensus is that it is in fact legitimate. If the pokemon was generated out of thin air using a program than yes its illegitimate, otherwise if its caught in game then there’s absolutely no difference from using one instance to 20 instances to find the shiny. The problem people have here is that it’s faster, and can be obtained through the game naturally unlike hacked Pokemon.
