Go to the 'You Arcade' and have a go on 'Hang-On' if you net over 10,000,000 points the Arcade Manager will give you a rare 'Hang-On' mini collectible.
Replay glitch
If somebody hits a home run off of the foul pole go to INSTANT REPLAY and show it in regular time, changing the camera to zoom out a little bit, and when it hits the foul pole, the announcer will say "Its off the foul pole!" I have done it before, but it is kind of hard to do.
