goldenrod city, look around in the underground or look up a walkthrough.
go to the undergroud place with the camera in goldenrod city then talk to the rocket member and he gives you a uniform!(what an idiot!)
No, but you can trade Pokemon only in HeartGold to Black
you can trade pokemon from heartgold to black but you can only transfer the pokemon in heartgold not trade it from black
you can transfer it from Pokemon soulsilver/heartgold to Pokemon black
in the tunnels below goldenrod city
You can transfer Pokemon, but you can't trade. Since HeartGold was released before Black, HeartGold doesn't know Black exists. However, Black knows HeartGold exists. You need to be on Route 16 in Black version, which requires beating the Elite Four.
No they can't.
the underground tunnel in goldenrod
You cannot transfer pokemon from HeartGold to Black until after you finish the main part of Black. Do note that you will be transferring pokemon from HeartGold to Black, not trading pokemon between the games.
you cant. you can only do that with Pokemon heartgold and soulsilver.
After beating the story and obtaining the National Pokedex. Go to Route 15 in Pokemon Black to the Pokemon Shifter Building. Connect a second DS running Heartgold. There you will be able to transfer up to 6 Pokemon from Heartgold to Black/White. Make sure the Pokemon transfering have no items and do not know HM moves(Cut, Surf, Flash, ect) You can not trade or transfer from Black/White back to Heartgold.
