How do I trade Pokemon from other games into my Diamond game?

Can someone tell me how I transfer Pokemon over from my LeafGreen over to my Diamond? I haven't done it in a while and can't remember how. Someone help please!|||First you insert your gameboy game into the socket. The game menu will then display an option to transfer Pokemon.|||You have the option to do so when you first turn on your game. Choose the pokes you want to import, then play the catching game in pal park. You can do this once ever 24 hours.|||The Pal Park is located on Route 221, If you surf south and east from Sandgem Town. You need to have the 'National Pokedex' to get in. Upon entering the park the attendant will give you 6 Park balls, that have a 100% capture rate. And, you only receive the transferred pokemon after catching all 6 of them. Hope that helped you. =).|||put game in gba slot|||Once you unlock the National Pokedex for seeing/capturing all 150 Pokemon native to the Sinnoh region, go to Professor Rowan's lab, where Professor Oak (think back to Red/Blue version, or the recent Fire Red/Leaf Green remakes that you have) shows up and upgrades your Pokedex. He tells you about the Pal Park, a new "minigame" that has now opened at the end of route 221 (South of Sandgem Town). When you go there, save your game and turn it off. Keep your Pokemon Diamond cartridge in the DS and put your Leaf Green into the Game Boy Advance slot. When you start your DS up, it might be helpful to choose to play your Leaf Green first to make sure the Pokemon you want to transfer don't know any HM moves (even if they still exist in Diamond/Pearl, like Surf) because you cannot transfer any Pokemon that knows a HM move (don't ask me why). While you're playing Leaf Green, it's also beneficial to give the Pokemon you're importing a Master Ball or another useful item to hold, because they will retain them as they make the jump from game to game. Once you're all ready, put all 6 Pokemon to be transferred into your PC box. Save, and turn off your DS. Turn it back on, and select your Diamond game. After you press start at the title screen, Underneath your file will be another box that says "Import from Leaf Green" (it changes to Sapphire, Ruby, Fire Red, or Emerald, depending on which games you have). Select that box, choose the 6 Pokemon you want, and it will transfer them into your Diamond cartridge! You're not done yet, though. Once the process finishes, load up your save file again and talk to the man at the counter in the Pal Park. He will ask you if you want to partake in a "Catching Show", and you should select "Yes". Before you do, however, make sure you bring a Pokemon that knows Surf in case you're importing any Pokemon that are housed in either the lake or the ocean sections. Once you start the game, run around in the wild grass and Surf on the water to find your Pokemon from Leaf Green! You can throw one of your 6 alotted "Park Balls" which have a 100% catch rate to recapture your Pokemon. When you capture all 6, you will be told your "Catching Score" and your Pokemon will be put into PC boxes. This works in both the Diamond and Pearl versions with any of the Game Boy Advance games. You can only import 6 Pokemon from any game pack ever 24 hours.|||Catch 6 pokes u want to transfer from leafgreen to diamond and put them in the PC. Turn on Diamond and find the option that says migrate from leafgreen. Click that and it will let you decide. Then go to Pal Park and they should be ready.|||When you finish the game and have seen all 150 pokemon in the region, go chat to proffesor whats his name and get a Pal Park pass. Then when you start up the game and yo can choose new game, continue and all that, you will be able to choose migrate from "Leaf Green", you then choose 6 pokemon to send to pal park. You then go to pal park and have to then catch the pokemon you migrated over.


Good Luck
