sorry u cant
how do you get arceus whit cheats in Pokemon heartgold
not possible dude
You can't catch Arceus without cheats.. You can get it when an event is going on about Arceus..
You can only get arceus without cheats if you go to an event.
the only way you can get arceus without cheating is by getting a mystery gift, you get them via wireless internet, look up when the arceus event is coming
get arceus then the game is easy lol there is none with action replay
only with cheats or by trading
Without cheats, you can only obtain Arceus through a Pokemon Event.
You can't.
you must get the azure flute and go to spear pillar.Use it and you will see arceus on a staircase.
I
it isn't possible without cheating
