There is also a Dual Slot Function, whereby you put a gameboy cartridge into the ds's gameboy cartridge slot. That way, some examples...
LeafGreen-
FireRed- Growlithe
Ruby- Mawhile
Sapphire- Sableye
Or if not, there is also a thing called MASS OUTBREAK. It is whereby an outbreak of certain national dex Pokemon (at random) appear at a location. To know what the Mass Outbreak Pokemon of each day is, fly to Sandgem City and talk to Dawn's sister (in the house south of Proffesor Rowan's, with a sign written "Dawn's house").
These two stuff can only be available after you get the national pokedex, though

You need to get the National Pokedex first.
you dont need any specifics pokemon, you need the national pokedex.
you must encounter every sinnoh Pokemon to get the national dex from professor rowan. after that, you can enter pal park (in route 221)
Nope, you can't migrate Pokémon without using the Pal Park.
You must obtain the National Pokedex. (And it's PAL Park, not Pearl Park.)
You can't trade, but you can transfer you're Leaf Green Pokemon to Diamond using Pal Park in Diamond. Pal Park can only be accessed after getting the National Dex. Its on Route 221.
In Diamond/Pearl/Platinum you have to get the national dex before you can enter the pal park.
you would have to have a Pokemon gba game in the gba slot with a charmander in it, have beaten your diamond, have gotten the national pokedex, and unlocked the pal park.
No but you just have to unlock the national pokedex to unlock the pal park then migrate them from any 3rd gen Pokemon game.
You can't unless you migrate by using the pal park...
cant YOU CAN MIGRATE IT FROM POKEMON FIRE RED OR LEAF GREEN AND GO TO THE PAL PARK AFTER GETTING THE NATIONAL POKEDEX
