OVER THE NET:
First, choose a one set game, play the sea-cup and enter one team
or two human players.  When it's your turn to serve, move the
non-serving player up to the top of the court close to the net.
This will force one of the computer players to follow him.  Now 
do a jump serve (push up and fire), then hit the ball to the other
computer player by pushing right then down.  The ball should drop
between him and the net and he should miss the ball.  Hopefully
this plan should work.  I don't know if it works with the other 
teams like Coco, Freaks etc but it works with the Rollers and 
the Golden Boys.


OVERKILL AGA:
Enter "NZL" for your initials on the high score table.  When you
restart the game you'll find you have infinite lives.


OVERLANDER:     
JUST A FEW TIPS - When cruising the highway don't stop shooting, and
always choose the highest paid mission.  Buy fuel carefully, only
enough fuel for that level, after level 1 you must buy a leanburner.
Try to stay in the middle of the road and travel fast, travelling
slowly only burns more fuel.  Fire bombs are more useful than smart
bombs when you learn how to use them.  Bulletproofing is necessary
after level 2.  When travelling through the barriers the best speed
is 90-120mph.
