Drill Dozer Cheats (GameBoy Advance)

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 Default 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.

Once you have earned the Hard Drill by buying it from the shop after it becomes available,
you will have access to a secret room in the tutorial world (MaiMai Room). This room
contains a 4-digit combination lock.

Before you can properly use this room to enter in secret passwords, you must first enter
an unlock code. There are 3 levels of Unlock Codes, each unlocking more passwords than the
previous.

To enter an Unlock Code, you must first reset the combination lock by selecting one of the
digits and hitting start while the drill is inserted - this will reset the code back to
0000. Once this is done, you must set each of the digits of the Unlock Code to their
correct number in the correct order. If you change one of the numbers out of order, or if
you connect to and alter the same number twice before completing the unlock code, then the
code will not work and you will have to reset the combination again by pressing Start. 

Once the fourth number is correctly set, the combination lock will auto-reset to show that
you have entered the code correctly. You may then either enter another Unlock Code, or
enter an Effect Code of equal or lower level.

Unlock Codes stay in effect until you leave the room. If you re-enter the room at a later
time, you must input the Unlock Code again to use more Effect Codes.
