Nothing, but if you trade the GameStop Jirachi, you get a new Pokewalker route. And currently, there is the "Yellow Forest" distribution via general WiFi. When you trade pikachu colored pichu to heartgold or soulsilver you are able to catch a rare Pokemon in a forest. I can not remember anything else. It's celebi.
You can find mespirt in : Dimond Pearl Platinum HeartGold Soulsilver Black 2 White 2 Pokemon Mysterdungeon Darkness/Time/ Sky (Maybe the new Mystery dungeon) (You may be able to catch mespirt in the new games, Pokemon X and Y)
Yes, you can. All you have to do is finish the game and then you are able to trade any Pokemon. like diamond, pearl, platinum, heartgold, and soulsliver.
If you take a rotom to the unworking lift in silph.co it will make the lift work and you will be able to get to the basement.
Find the lost little girl and play Hide and seek with her, then you will be able to get off of the boat.
rumours are you will be able to catch groudon kyorge rayquaza and giratina in both Pokemon heart gold and dawn silver
You may be able to catch it in the Safari Zone. Also another place (providing you have completed the Pokemon league) is Mt. Silver on the grass patch near the Pokemon center. you can also catch it in your pants.
Ash is not in Pokemon HeartGold, but Red is able to battle on the Summit of Mt. Silver.
Yes. You will be able to find Hoho on top of the bell tower after you have the rainbow wing and the clear bell and you can get lugia too
You have to be able to go in the kento region, then go in the: Viridian Forest, and while in there, you should run into a wild Pikachu, catch it, and you have your own Pikachu
Yes.
What you do is trade that Kyoger to a friend that has Pokemon soul silver for Groudon show that Groudon to Mr.pokémon and he will give you the Jade Orb with that orb you will be able to catch Raquaza. hope this helped
It's your opinion, but in HeartGold you can catch Ho-oh, Suicune, Raiku, and Entei, and in SoulSilver you can catch Lugia, Zapdos, Moltres, and Articuno. There are also more Pokemon available in HeartGold than SoulSilver. Edit: The person who last answered this question is wrong, you can catch all of the above Pokemon in both games, not in either or. I know this because I have soul silver and I have suicune, raiku, Entei, Ho-oh, Lugia, Zapdos, Moltres, and Articuno; so obviously you must be able to catch them in both.
If you don't include trades, I think you are able to catch these. Ho-Oh, Lugia, Suicune, Entei, Raikou, Mewtwo and Latias. I have heard that you can catch Groudon/Kyogre (Only one of them, the other one is available on Soul Silver) and Rayquaza, but that I'm not sure of.
To be able to find more unown!
Catch Arceus. Masterballs, or just weakening it until you are able to catch it.
Yes you will, and you can preorder it now for $39.99
