You have to trade it from soul silver to heart gold this is the only way
if you have an action replay you can get lots of cheats from neoseeker.com
do it yourself
No, the only way is to do cheats or an event, and there are no more events for Pokemon Heart Gold because there is a new Pokemon game they are doing special events on.
you can using cheats,trade or using pal park but without 1 of those 3 u cant
you can't do that you need a action replay or R4 if you want cheats. or.... you could probably use the events to get legendaries.but i know you can't use cheats without a action replay
no
Get Pokemon emerald and then you can get all three without cheats or trading
Probably trade with Ruby.
no, groudon is available in soul silver only, so you must trade from soul silver, however if you use cheats, the groudon will not unlock rayquaza.
You cannot obtain Celebi in HeartGold without cheats if you missed the event.
without cheats only 1
not possible dude
no you can't you have to either trade or gameshark cheats :P
After you caught Groudon from the Hidden Tower talk to Mr. Pokemon (First you have to have heartgold to) Youhave to have kygro in heartgold make that person in heartgold trade, And when your soulsilver person has kygro then talk to Mr. pokemon he gives you a green orb and then go back to the hidden tower. go inside and there is rayquaza! You have to have a pokemon higer then lv. 50.
