How do you get to eight and nine island on Pokemon firered and leaf green?

Beat the Elite Four and the Champion, then make sure you catch at least 60 Pokémon. Go to Prof.Oak and talk to him, he should give you the National Dex. You can visit the Seven Sevii islands,by going and talking to Celio. But to visit Islands 8 and 9, you must go to Nintendo Events to download Mystic and Aurora Tickets. But if you have a Gameshark or Action Replay and are willing to cheat a little then use the codes below: But please note that once you put in the code, walk through a door, and you will reach the Islands 8/9, but then take out your cheating device to prevent further warps. Please ENSURE that.
