Getting the Dark Bomb
First, throw a lava toward him. He will shoot with the bird thing. Keep doing this until you defeat him.

Getting the Guardian Boots
In Starlight, after you get the lightning bombs, return to the start. Enter the next area. Push on the middle left, where a golden statue used to be. You should enter a room. Lightning bomb the platform to get the Guardian Boots. You can now permanently kick bombs.

Getting the Guardian Vest
Note: Earth bombs and lightning bombs are required for this trick. On Aquanet, just at the beginning on your right are three pillars. Use an earth bomb here. Enter the hidden doorway on the left. Lightning bomb the platform to get the Guardian Vest.

Buying costumes or weapons
Go to the planet selection screen and press [R]. You can now buy items with the coins you collected during the game.

Glitch: Silent bombs
Lay a bomb, then quickly pause game play as soon as you see it explode (before the bomb blast disappears). Wait until the explosion sound stops. Resume the game. The bomb should explode again, but with no sound.

Glitch: Never-ending KO sound effect
When Bomberman gets knocked out, pause game play. The sound effect should still be playing.

Glitch: Two Pommeys
Use the "Silent bombs" glitch. Select the dark bomb. Pommey will get sucked into the blast and it will appear as if there are two Pommeys.

Glitch: Use any stones in demo mode
For this trick to work, you need to have a saved game with at least more that one elemental stone. Any other stone will work -- just not the fire stone. To start, make sure your game is reset. When the title screen appears, go into your saved game. You can choose any planet, but the easiest one to do this trick on is the entertainment planet. Once the level starts, choose which stone you would like with the "C" buttons. Start the level and let yourself die with the stone still selected. You must not kill yourself, or this trick will not work. Allow the enemies kill to you. Once they do, the hard part is over. Put the controller down. At the "Game Over/Restart" screen, do nothing. Let the countdown exit you to the main screen. The stone is now registered into memory. Wait for the demonstration to automatically start, with the elemental stone you have chosen. Try choosing the Wind stone to see people get blown off the world a lot and Pommy even defying gravity. Choose the Lava stone and Bomberman will not get hurt. Note: This will freeze the game part way through. Reset the game to start over. Try your own stones for more effects. If you want to see it again, you must reset the console. This also will not work for demo part two.
