Also, yes, you can get Ho-oh. He is still in the Tin Tower and (in this version anyway) you still get the Rainbow Wing in Pewter City. He's still in the upcoming update too, but I changed how you get the Rainbow Wing. But that's getting ahead of myself.
Great! I'm practically done with the game-I've caught Lugia, Legendary Birds, Ho-Oh, Mewtwo, beat Kanto, and is working on getting pokemon I like (I'm currently trying to get money so I can buy Mew from the Casino in Goldenrod City!) Just a tiny thing you might wanna change: When I look at the ABC mode in the pokedex, Leafeon shows up in place of Dunsparce (In the middle of D and E, that is) and Glaceon shows up in place of Tangela. If you could fix that, it might be helpful THX!
