What are you guys talking about? You CAN'T synch a gamepad with a console. The gamepad that comes with the console is manufactured to be permamently linked to it. If you breake it, you can't get a replacement yourselfe. You need to send the whole console to Nintendo so THEY can synch another one to it...
Correct me if I'm wrong though.
But I'm pretty positive that if there are no hardmod/homebrew ways to do this, you can't do it yourself in a legit way...
Make a double research before you buy or you'll get screwed pretty bad :/
