An easy way to beat Altair is to place lots of bombs around him. Then when he combines with his ship, kick a bomb into him and while he is dizzy, pick him up and throw him off the cliff.
First, you need to be at the first world(Green Garden)on world 3(To have or to have not). Then, go to one of those platforms that work like elevators. Once there, put a bomb under the platform, go to the top of it, and let an enemy hit you. Blast the bomb so you go up, and when you land, you will be standing up as if an enemy had knocked you.
When you are on the menu where it says adventure battle etc, press the start button continuasly until you hear a chime. Then go into battle and you will have 4 extra levels. If you don't press it fast enough you won't get the levels.
All you have to do is make your opponent dizzy, then as soon as possible walk up to them and pick him/her up by pressing "b". Now just imagine you have a bomb instead and throw him/her off.
Press B and A at the same time and then keep pressing a until the bomb light up use the b to throw, now if u want a powerful bomb you need to pick up an item that looks like a star plate and a red bomb if you use that bomb and make it into a big bomb it will explode so big that it can destroy some of your enemies(if they are only close).
When Bomberman is dizzy, rotate the Analog-stick for a faster recovery.
At the main custom Bomberman menu, press Z or R.
Collect all 120 gold cards (100 from the normal worlds, 20 from the Rainbow Palace). Then, a "Full Power" selection will appear on the options screen. This option allows any level to be started with maxed out Red bombs, and the remote item.
Beat the first four levels of the game on the normal difficulty level of adventure mode.
Beat the Rainbow Palace world by defeating Sirius. Then, a new selection that allows the credits to be viewed will appear on the options menu.
Press start as possible at the mode selection screen.
Find all one hundred Gold Cards and defeat Altair.
A new battle mode level (In the Gutter, Sea Sick, Blizzard Battle, and Lost at Sea) will be available for each world that is completed in Adventure mode. Alternatively, highlight the "Battle" option on the main menu, then repeatedly tap Start. If you entered the code correctly, you will hear a sound. Note: For the Japanese version of the game, use a Joy Card 64 controller. Set the controller's slow switch to the "Hu" position at the title screen and wait for the sound that confirms correct code entry. Then, four new levels will be accessible in battle mode.
