Sound Test Menu#

Activate the following MAME cheat before the title menu loads to be redirected to a sound test menu. For the moment, the text display does not load correctly.

Controls:

• 1P Up/Down - Switch function
• 1P Left/Right - Switch ID
• 1P Button 1 - Play
• 1P Button 2 - Stop
• 2P Button 1 - Refresh screen

There are 10 functions in total; the first three ones play sound effects, the sixth one plays music, and the seventh one plays voice samples. It is unknown what the other functions do, or even if they work.

Unlock Code#

To permanently unlock the EX Stage The North, the player would normally be required to connect a memory card with save data of the PlayStation or Dreamcast versions of Mr. Driller with either the Time Attack Mode or 1000m Stage cleared to the cabinet; this was only possible in Cyber Lead II cabinets, which had a Slot Link System panel with support for both PlayStation Memory Cards and Dreamcast VMUs. (The NAOMI Universal Cabinet can also be used, but only for the Dreamcast version's VMU.)

However, a second, more obscure method is also known to exist:

1. Go into the game's operator menu and enter the A.D.S. menu.
2. Afterwards, press the following buttons in order:
   P2 Start, P2 Button 1, P2 Button 1, P1 Button 1, P1 Button 1, P2 Button 1, P1 Button 1, P2 Button 1, P2 Button 1, P2 Up, P2 Down, P2 Left, P2 Right, P2 Start, P2 Down, P2 Up, P2 Right, P2 Left, P2 Button 1, P2 Button 1, P2 Left, P2 Right, P2 Down, P2 Up, P1 Button 1, P2 Right, P2 Left, P2 Up, P1 Button 1, P2 Button 1, P2 Start
3. If the code is entered successfully, "ON" will appear on the bottom left of the screen, and the Extra Stage stats will be displayed, like the picture below:
