Ok, so I've spent most of my afternoon while I worked researching multiple methods that everyone has posted here but every time I found one that I could possibly use like the bar codes one, or the oot one etc it seems they are no longer valid? Cause they were patched? Is there any way for someone to link me or tell me a working guide that I can possibly use? would love to try and get some of the pokemon that I'm missing especially event ones. I appreciate any help I can get thank you.
