Sorry, you can't.
truthguy/mushking: im not even sure you can get it on GameShark ive been looking evrewhere.
Pokemon Channel, Pokemon Colosseum Bonus Disk, or Nintendo event.
Nintendo Wi-Fi
you need both ruby and Sapphire to get there. :)
you CANNOT get Lunatone without inserting Pokemon sapphire in ds
You can't.
Go to Granite Cave in Ruby/Sapphire/Emerald
Six without trading.
hach an egg or surf
You just cant
The only way to get manaphy without Pokemon ranger is to get it from a Nintendo event.
Sadly you can't without cheating. You must trade it from Ruby or Emerald to your Sapphire.
