Answer : Action Replay Code Arceus (Pearl)

Answer 1

You need to use the following code :

94000130 FCFF0000
B21C4D28 00000000
B0000004 00000000
0000AA3C EDB88320
2000AA68 0000000A
D2000000 00000000

Now, when entering a PokéMart, press L and the R - button on the same time and talk to the attendant in the PokéMart. He will give you an Azure Flute. Go back to the Sky Pillar and play the flute there. You'll have the opportunity to catch Arceus.

Good luck catching Arceus and have fun! :)
