To access this feature look down at your hand when you are locked up at the 'Title' screen and keep pressing ZL + ZR on a Classic Controller to escape from the chair. Then move around to the area behind the chair to find an old computer terminal that you can type the case sensitive code 'DOA' (without the quotes). You can also plug a USB keyboard into your Wii to enter the codes and play the Zork text-based adventure game. Click here to view the video
