It depends on the game. Only Pokemon from a GBA game can be transfered after the Elite Four have been beaten and you've recieved the National dex. Then, go to Sandgem town and down to the beach. surf down and to the right for a ways. You will come upon the Pal Park once you reach dry land if you continue right. At this point, save, turn off the game and reboot. At the file screen, go to "Migrate from [game]". Choose the six Pokemon you want migrated. Go into the game now, and go into the Pal Park, where you recatch all of your migrated Pokemon. Don't worry about losing your pokemon either,because the balls have a 100% catch rate.

You can't hook a gameboy to a ds if thats what you are attempting. You have to put the gameboy game in the GBA slot in the ds, and then you have to go to pal park and transfer them to your game. It isn't trading, as its only one way, all the HMs the pokemon knew have to be deleted, and you can't send them back. Hope this helped!

u need 2 see 150 pokemon then find pal park the save at pal park and then turn off then on then a new slot comes but u need a gba pokemon game in and copy then ask the guy to play then the pokemon r in the park then catch

thats easy. take your game boy pokemon game and take out the little cartridge on the bottom of the ds and incert it there.

you have to have beaten the game and go to the palpark and choose the pokemon that you want to transfer
