=>Duck Patrol: CNTRL I can control the ducks in one of the game modes.

 ->Freeze Trick: Press START to pause, then unpause. The screen will remain
frozen for a very small amount of time, giving you a chance to shoot those
critters.

 ->Super Cheat: Take a NES advantage joystick, and "tape" the joystick in the 

up/right (diagonal) position.
Now when you play Duck Hunt, the ducks will 

always fly up to the upper right ahnd corner, thus you know where to aim!
