in diamond and pearl, you go to jublife city go to TV station go to the 3rd floor where the records are dont go inside the records place talk to the man inter vewier he says something. say everyone happy. everyone and happy have to be separated. then wifi connection. wifi and connection are separated. after that, he says he will give you a mystery gift. save then shut the game off then turn it back on then if this thing says mystery gift, go on that and then you get it. check your wifi conection settings. then after you get it i think you go to canalve citys pokemart then talk to the mailman and you receve membres card. then go outside then go to the house on the right beside the girl with her psyduck. go in and you apper at new moon island then soon youl meet darkari. hoped i helped!
