A - Enemy Stop Shooting : on the first stage, kill everything but the two Bees in the bottom left corner. Then just wait, 
                          dodging the enemies' shots, until the enemy no longer drops any shots towards you. After the enemies
                          stop firing, let them pass for two more trips and then kill them. For the rest of the game, the enemies
                          will not drop shots. It will take approximately 15 minutes for the enemies to quit shooting at you, 
                          so this trick requires a lot of patience. Note : in a 2-player game, only one person has to do the cheat 
                          for both players to benefit. But as soon as one of the player's game is over the enemies begin shooting again.


B - information (BUG) Take The Control Of The Fighter For Free : during the Galaga demo, the Boss Galaga comes down and tries to 
    tractor-beam the Fighter. As soon as that tractor-beam starts, the player can take control of the ship in the demo.
    The player has two choices here and this will effect how the game handles this bug : If the player allows himself to be captured,
    the demo will continue as normal and he has the option of controlling the player Fighter or not. 
    The player can choose whether to save the captured Fighter, try to complete the level, etc. The demo mode will complete after
    30 seconds and the high-score screen will appear. If the player takes control of the Fighter and destroys the Boss Galaga 
    with the tractor beam, some of the characters on the screen will freeze while others are still moving and doing what they are
    suppose to be doing. This will last 15-20 seconds, then the game will go to the high score screen.


C - information Challenging stages are easier if the high score numbers are used to refine your aim. These tips assume a 6-digit high score :
    1) On the first two challenging stages, aim your ships so that your left set of bullets falls between the second and third numbers
       in the high score list.
    2) On subsequent challenging stages, aim one set of your bullets between the first and second numbers in the high score list
       (if the units come from the left) or between the last and next-to-last numbers (if the units come from the right). 
       This will allow you to hit descending enemies at the highest possible point.


D - information Here is a neat (and useless) Galaga trick : It is possible to end the game with a 200% ratio. The 200% hit-miss
    ratio trick can only be done with your first shot of the game. When the game starts, don't move, and fire only one shot. 
    If you time it correctly, two enemies will be killed at once. 
    Let your remaining Fighters be destroyed, and presto : a better-than-perfect result.


E - information Easter Egg :

    2) Keep B1 pressed and enter the following sequence : Right(x5), Left(x6), Right(x3), Left(x7). 
       '(c) 1981 NAMCO LTD.' will be added at the bottom of the screen.
