Drill Dozer Cheats

Once you have the Proof of Mastery item, you can select Hard mode on the file select screen by holding down L+R before you hit the Start button.

Once you have unlocked the Full Gearbox using the secret room in the tutorial level, you are able to replay any world with all three gears by using its effect. To activate it, hold R and press Select while on the world select screen. The Screw Bit will turn yellow to indicate that you have activated the Full Gearbox.

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.

Purchase the Hard Drill when it becomes available at the shop. It will allow you to access the secret MaiMai room in the tutorial world. In the room is a four digit combination lock. There are three unlock code levels that each unlock its passwords, as well as the passwords of the previous level(s). First, choose one of the digits and press Start while the drill is inserted to reset the code to 0000. Then, set each of the digits of the unlock code to their correct number in order. When the correct unlock code is entered, the lock will automatically reset. You can continue entering another unlock code, or enter one of the effect codes for the level unlocked, or a lower level. If you leave the room the unlock codes must be re-enterd.
