Double fighter (Galaga)
 
 Shoot one of the green ships on the top row to turn it blue. When one
 of them dives alone, avoid its shots. Intentionally allow your
 fighter to be captured by its tractor beam. With your next ship, wait
 until the joined ships to dive. Shoot the alien while carefully
 avoiding your captured fighter. You will have a double fighter with
 twice the firepower. 
 
 Keep Galaxians unarmed (Galaga)
 
 In level 1, allow all the enemies to get into formation and note the
 bottom left bee. Kill all of the other enemies except for that bee.
 When just that bee remains, place your ship in the lower right
 corner. Allow him to fly around and attempt to attack your ship.
 After one pass with him not firing, allow him to pass again. If he is
 still not firing, shoot him during this second pass. This will take
 approximately 15 minutes. Doing this will disarm the enemies for the
 remainder of the game. 
 
 Quick start (Pole Position)
 
 Shift to low until you reach about 160 kmh, then shift to high. This
 will result in a nice speed boost, and if you have pole position, an
 instant lead.
