I mean it depends on if you have action replay or not. Because if you action replay you get use full poke dex then save it. Then do darkrai event (there an anwer on how to do the darkrai event). Then again if you Do'nt have have action replay Then that's another story. See first to answer your fisrt question yes if you do'nt have action replay you will have to beat the elite 4 and the Chapion ( or how ever spell it). Then your going to have use wifi to have a nintedo event ( warning there are more that one nintedo event and you need wi-fi to get a nintedo event). and so that ends my answer and bye
Birth Island, but you will have needed to get the Pass to get there first which is an expired event.
there was a Nintendo event that gave you it, but its over so you must use action replay
