I mean, how do I get my files onto my game!
You use Pokedit by first switching the DNS number in your DS/DSi Wi-Fi settings
then, select a Pokemon and click send to game and then go to the GTS.

Edit: If you want a file on your game you have to send your game to them and use the file that you created. (This costs $$$)
