So I'm trying to find a legit PID for an Adamant Giratina with Ivs: 31 HP, 31 Atk, 30 Def, 30 SpA, 31 SpD, 30 Spe with PokeFinder, but it doesn't give me any results. I have tried in Diamond, Platinum and HeartGold. I don't know if changing the TID/SID can work? Is there anything I can try? Or there isn't any way?
