If you would like to hear all of the incredible sounds and music in this game, just try this method. On the title screen, press RIGHT and DOWN very quickly while rapidly pressing the X button until you hear a ringing sound. The sound test screen will appear after this has happened and you may now choose from an array of sounds and music. If you have a rapid fire control pad, set the X button on automatic and do the trick.
If you have a rapid fire control pad, you can do this trick. First, start the game and put the rapid fire on the X button. You will see the weapons at the top of the screen change back and forth very rapidly. Once you get two different weapons, you will see that you can use both of them at the same time. This will help you in defeating some of the tougher enemies and bosses throughout the game. The only weapon that this is not good with is the flamethrower, which will not respond to this trick.
