First and foremost, I'm sorry if there already is a topic about this. I tried to search for it in the forum and didn't find what I was looking for (made an account just for asking). If that's the case, please forgive me and share me the link to that discussion.
Now, with that out of the way, my question is: is there a way to edit static encounter pokemons? To be more specific, I'm kinda working on a livingdex to put in HOME and so I'm revisiting every game, starting from old gens. Currently playing Ruby, I'd like to have a flawless Groudon, but editing the one from Cave of Origin, I get the invalid PID correlation error. So again, can I edit that Groudon (and other legendaries) or do I have to find another way to force those stats on them?
