You need two ds lites then one game should be original and the other one should be r4 or edge. In the r4 or edge you must activate the cheat of arceus then once you've have it, trade it to the other ds lite.But make sure you trade from the pkmn center at the 2nd floor.
You can't without hacking, unless you have HeartGold and SoulSilver. Why, one word, HM Moves, Rayquaza can't migrate, you need to get Rayquaza on the Nintendo DS. (This requires HeartGold and SoulSilver. You need both, you'll see why...)
not without a glitch or hacking
without cheats only 1
You can never get Mew without hacking or getting it from a hacking friend. Besides, its Mew and Mew2 O_O

arceus. you have to trade over from either pearl, diamond or platnium, palkia, dialga and giratina to either heartGold or soulSilver.-RR14
Growlithe is one of the "version-specific" Pokemon. Growlithe is only available in HeartGold, while in SoulSilver you can only get Vulpix.
Without trading or cheating, it's impossible. You can trade from HeartGold/SoulSilver or get it from Pal Park with FireRed or LeafGreen.
Once you ask the Copycat in Saffron City to get her Clefairy Doll back Talk to the man inside The Pokemon Fan Club.Then he will give you the Clefairy Doll go outside.Then Steven Stone will talk to you he will say that Latias(HeartGold)or Latios(SoulSilver).Finally Latias or Latios will roam Johto or Kanto.But sorry,you can't get Latios without Cheating,Hacking or Trading. :(
If you downloaded the special Darkrai mission you can transfer it. The special mission has expired and is not available anymore without hacking.
You can only get pokemon if you have a diamond, pearl, heartgold, or soulsilver game. Otherwise you have to use a rental pass.
