Bomberman Max 2: Red Advance Cheats for Gameboy Advance
Charabom that makes you very powerful:
Obtain a Elephan and Dorako in the Garden stage and fuse them together to make Elefandom which is a Charabom that will give you full power and the maximum amount of bombs.
When you are holding the Invisible Vest press A repeatedly just as the bomb you set explodes to protect yourself. As the Vest wears off be carefull not to blow yourself up.
To avoid losing your Charabom turn off the power immediately before losing when you are playing in a two player battle and your opponent will get a free Charabom and you will not lose one.
