Is it possible to get most of the Pokemon in Pearl without trading?
I know that Pearl and Diamond have different Pokemon, but I'm wondering if there's a way to fill up my Pokedex (except the starter Pokemon and any Pokemon specific to Pearl or Diamond) without trading? I know that I can stick a GBA game into the GBA port on my DS and do it that way, but I only have Leaf Green and Emerald (no Fire Red, Ruby, or Sapphire), and one DS. It would be too expensive to buy a second DS and all the other Pokemon games, and I don't know anyone offline who plays Pokemon.
Just want to know what percentage of the Pokedex I can expect to fill with Pearl, Leaf Green and Emerald alone, before I begin.
Also, on the DS, does "wi-fi" really mean "be in the same room"? I know that if you have a PSP and a PS3, you can play your PSP online over vast distances. Can the Wii do this with the DS?
Thanks in advance.
