Where to find suicune in pokemon heartgold?

you cant catch suicune in all the Pokemon games except gold silver and crystal but if you hack u can catch it.

edit* actually you can catch it in firered leafgreen (you have to pick charmander as your starter) on route 2 after you beat the elite four and you can catch it in heartgold soulsilver outside of bill's house in cerulean city in kanto (after you beat the elite four)
