To get free nice cards, just go outside and chat with another Pokemon. They will
ask you a question. If you answer correctly, they will give you a Free Nice card.
The Nice cards are the Pokemon who asked you the question. For example, if you
answered a question correctly from a Mr. Mime, you will get a Mr. Mime card.
Fast forward through shows
To advance through the segments of a show on the TV, press L then R once right
after each other while watching the TV channel you want to fast-forward. You will
switch back and forth on the channel menu but not actually watch the other
channel. Repeat this to see the next segment.
