the EA sports games are extremely slow games. Your processor is just not fast enough for them. Madden 2006 barely runs 60 fps on my Core i5 3570K, for instance, and it still drops during certain camera angles.
About your controller, it's probably just configured wrong. Go back through the dolphin gcpad configuration on the sticks and it should work right next time.
