Simpson's: Hit & Run, The Cheats (GameCube)

- Infinite car health

- Speedometer display

To skip a mission,  you have to fail a mission 5 times and then
  in the menu you will have the option to "skip" sometimes you
  will have to fail a mission 6 times. It's common sense if you have
  played Road Rage, in the Missions fail it 5 times and you skip it,
  same as here! NOTE: THIS DOES NOT WORK ON THE LAST MISSIONS FOR ANY
  LEVEL

  

In the first level of this game you can find a rocket car. Find the
  power plant and take the tunnel all the way through. When you arrive
  out you will see large mansions. Go straight out, turn right, then
  left and immediately to your left will be a gold house. walk up to the
  front gate and you will see a rocket car from that old episode... you
  know that one. Get inside with y. Keep in mind that this car is
  extremely fast and not so durable so be careful!

  middle of the street.  And wait till a car stops in front of you. 
  And when it says press (y) to enter. Don't do it.  Instead, press
  (a) and jump on the back of the car that stopped by you.  It
  works best with the ghost boat because, there is a lot of room on it.

  seconds, the car you are on will begin to move and homer will act like
  hes surfing.  (The car will take you all over the level)

  jump on the mechanism, and then jump up and kick the boards. go down
  the corridor, and you will see the giant chess board. you can go up
  the stairs and you will find two buzz cola coin boxes. also if you
