FIFA Soccer 64 Game Cheats

Easy Way to Score
Put the difficulty on novice. Go around the goalie (it will be easy) and you can dribble the ball into the net without opposition.

Easy Win
During a match, pause the game and access the Controller Select option. Then move the controller icon under the other teams flag. When you go back to the game, dribble the ball into that teams own goal. Repeat this process until you have enough points, and before the match ends, make sure you switch back to the winning team. You are assured to win every time!

Taunt Your Opponent
When you are playing in a match, if you press in any direction on the control pad (or the analog stick if you use the control pad for movement), the crowd will "BOO" the other team. This can be particularly effective when your opponent scores a goal.
After you score a goal, experament with the C-buttons to make sounds like the other FIFA games.

More Annoying Sounds
After scoring a goal, while the player is doing his victory jog and during the instant replay, pressing the C buttons causes sound effects. Top is horns, left is the crowd yelling, bottom is a drum, and right is a man yelling "Gooooaalllll!"
