Make sure you have the Iron Racket equipped, then go to the training courts. Go up to the
lake and follow it until you see a boy practicing his swing. Tell him you do not like it
and you will show him your swing. He will laugh, and you will get angry. Next, get ready
to swing. In ten seconds, press A as many times as possible. If you press it 100 times,
you will get the Silver Racket. If you swing it 150 times you will get the Gold Racket.
Note: Try wrapping your hand in your shirt and rub it over A until it ends. You
should be able to get either racket this way.
