Alright, is there a video or a tutorial you would be able to guide me with? I actually never even heard of PkHex until now (I don't have it installed either) and I'm not sure how the procedure works.

Hello, so I recently just bought pokemon Brilliant Diamond and I am extremely late to getting the Manaphy egg, Shaymin, and Darkrai. I really wanted to shiny hunt them and that's only available in this game since they're not shiny locked. Is there anyway where I can still somehow get the items that allows me the encounter them or get the egg? And if someone does find a solution, would you be able to walk me through it? Thanks.
