Start the game with the regular control pad and go through to the begining of the game. Pause the game and replace the control pad with your stunner. The cross-hairs will remain on-screen at all times.

At the beginning of BEGINER mode there will be a bad guy popping out of the door. First kill him and shoot the door until it is straight. You will get a machine gun.

In the expert level, just before you enter the room where you get the rifle you'll see two paintings. Shoot them both until they're gone. You'll find a machine gun behind each of them.

To gain more time on the name entry screen shoot the backspace button 20 times and your time will refresh to 99 seconds.

When you first go down into the basement, shoot at the red barrel next to the truck and a rifle should appear.
