This page contains Drill Dozer Passwords for GameBoy Advance called "Secret Password" and has been posted or updated on Feb 13, 2008 by jkalebh930. Let us know what you think of this Password by thumbs voting.
Once an Unlock Code has been entered in the secret room in the tutorial level, you may enter one or more Effect Codes of equal or lower level. These codes may be entered freely and without any specific method - there is no need to reset the combination lock at any time unless you need to enter another Unlock Code.
Entering in a correct Effect Code will cause a chest to appear from the purple brick pipe in the room. Simply walk into the chest to claim the prize. Certain chests (the wallpapers, for example) may be collected multiple times to alter the current effect. In particular and as an example, the Standard Wallpaper chest will not appear until you have changed the current message border to something else.
Note that these codes will not work until the correct Unlock Code has been entered since entering the secret room. The Master Seal and Full Gearbox enable certain key combinations on particular screens for extra effects, detailed in the code section. The Soundstone opens up a Music/SFX Player in Gearmo's Save Menu at the Trailer. The Wallpapers change the border around messages and the inside of the Red Dozers' Trailer. And the Costumes allow you to change Jill's appearance by highlighting her in the trailer and pressing either the L or R buttons.
Finally, two Effect Codes have further requirements before they will work. The Soundstone chest will not appear until you have found the Soundstone treasure in Area 1-2, and the Full Gearbox chest will not appear until you have collected all 31 treasures, earning the highest rank: Crime Boss.
