Hey, I know it's an old thread but still I need your help please. I used the Celebi code that you gave, and it worked well, the Celebi was in the Box 1 Slot 27. But when I bring it to Ilex Forest and communicate with the shrine, nothing happened. Is it because I already far away in the game? I already beat team rocket at Goldenrod Radio Tower long ago and already beat Clair at now is omw to route 27 or road to pokemon league.
Please help me, I really wanted to go back in time and beat the crap out of Giovanni haha
