Hello, I am new to this forum, and new to the use of pokegen. I will happily take a redirect if my question is not in the appropriate forum.
While I have used several tutorials, I have only generated a few pokemon. I have come across no issue in generating normal pokemon-- save for "legal" shinies, and "legal" shiny legendaries.
I'm looking to generate a shiny celebi next (for collection not for trade or battle) and am wondering how to do so without error.
I do not have an original ID to use, so I am borrowing those from other sources, or generating my own false ones. Because of this, Pokecheck often returns the message that the ID/SID is illegal. What does this illegality mean exactly? Does this affect Pokebank deposits, and how do I avoid it?
