Well, first of all, you must BUY an action replay, if you want codes, or it doesn't have codes on it, you go to codejunkies.com and click your part of the world. If you put codes that are for the European version of action replay, but you live in America or Canada, they won't work.
Second, if you want to find the codes for the game, click Codes & Saves, change the platform your playing the game on, (which for this, would be Nintendo DS) and then type in the name of the game.
Then you put them in, and turn the codes on, and there you go, action replay codes for Pokemon HeartGold, for Nintendo DS!
Also, remeber that if you put in the SoulSilver codes, they won't work for HeartGold, and vise versa. Just a tip.
if you have an action replay you can get lots of cheats from neoseeker.com
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
There's no Action Replay code for Zoroark in Pokemon HeartGold, because Zoroark does not exist in Pokemon HeartGold.
