Silver and Gold Rackets:
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.
To get a Gold Racket easily, once you get the Iron Racket, equip it and go to
the lake at the training court. There should be a boy swinging. Talk to him and
say that he has a bad swing. You will now be able to swing for ten seconds. You
are instructed to tap A as fast as you can, but you can also press B. Get a
friend to help you, with one of you pressing A and the other B.
