Just as in the arcade game, the Nintendo 64 version has the same cheat. In stage one, allow all enemies to get into formation, the bottom left-hand bee is the key to the cheat. Kill all of the other enemies except for him. After eliminating everyone except for him, place your ship in the bottom right hand corner. Allow him to fly around and attempt to bomb you. After one pass with him not firing, allow him to pass again and if he is still not firing shoot him during this second pass. This will take approximately 15 minutes. This will disarm enemies for the rest of the game.
