How do you use friend codes how far does the wifi go in pokemon diamond for trading and battling and stuff?

Answer 1

well friend codes are the ID for each of your friends they are used in large conventions where evryone has a pokemon game with their wifi on soo that kainda picks each one out

since wifi range id say a good 15meters , you can always try it out walking away from each other untill the game freeses
