ya u fight petrel in the directors office hes disguised as tha director. he mostly has koffing but he also has a weezing. i think e koffing r at level 32 or 30 the weezing is around 34 hes pretty easy depending on ur Pokemon but good luck =)
first, get to the director's office in the radio tower and beat petrel. he will then give you the basement key for the locked door in the undreground tunnel. once you go in, you will be chalenged by your rival, so be prepared. in the room with the switching doors, hit the 3 switches from left to right to get to the next door. there is, however, a smoke ball in the switching door room, so I suggest getting that too. in the next room, follow the path while beating the grunts to get to the director who will give you the card key to get to archer and save the radio tower! the director will then come and give you the rainbow wing (or silver wing in soulsilver).
you get the silver wing after you defeat team rocket went they take over the golden rod radio tower prof. elm will call you about the broadcasts from the radio tower after you beat the gym in mahogany town
you can´t
First, go into the building that sells stuff. Beat team rocket in there by going down the stairs, fly to Olivine City and beat Jasmine. Fly back to Mahogany Town, and the guy will let you pass.
go to goldenrod city and defeat teamrocket at the radio tower. PS go to the underground tunnel first a goon will hand you a uniform thinking your a new recruit cool or what but u cant leave the city so go to the radio tower
This was a problem that I was having a lot when I played the Johto games. after u beat pryce and get team rocket out of the radio place, go to goldenrod city in the radio tower and battle team rocket in the tower. be careful, in the tower, you will have to face some old rocket rivals like adriana, proton, and petrel. after you beat archer, who will standing on the observatory floor, in the tower, you will then be able to pass the guy. (p.s the ragecandybar in absolutley useless)
you have to beat jasmine ,beat team rocket executive petrel and ariana and all the electrode that are powering rthe radio transmission then go in to the gym and beat him
You have to get into the tower and beat team rocket.
beat him
you beat them in a battle
You have to beat team galactic and then talk to the man that is out side of the radio tower.
in the radio tower
Beat the grunts, get the key from the Radio Tower Chairman at the hideout, beat Archer and Ariana
To get to Blackthorn City (when your ready) you WILL NOT GO THROUGH THE DARK CAVE!!!!!!! You go to Goldenrod city and go to the underground tunnel at the top of the city. then you go right at the first turn then talk to the dude and he gives you a rocket costume then go to the radio tower and beat up all the rocket grunts and Petrel. then you go to the underground tunnel after defeating Petrel) at the bottom of the city and take a right. go through the weird door and beat up the rockets. after you save the director go to the radio tower again and beat up all the executives (don't worry there is only 2) then go to Mahogany town and the guy that stops you won't stop you. it took all my skills.
You beat Team Rocket in the Radio Tower. And then the Owner of the Radio Tower or whatever he is gives you the Rainbow wing at the top of the Tower.
In the warehouse in goldenrod (make sure you have beaten the radio tower, and have the basement key) go to 3F of the radio tower and open the shutters then battle to beat them
after getting your 7th badge (you have to have 7)go to goldenrod underground and get your team rocket suit then go to goldenrod radio tower and go to 5f then beat petrel and youll get the basement key go to golden rod underground and youll see a kimono girl go thatt way and unlock the doors and beat the team rocket grunts and youll see the directorand get the card key then go to 3f in the radio tower and unlock the doors and beat the rest and youll get it
