Select game 2 or 3 and enter the maze in the Black Castle. Move screen to the left of the first maze screen. At the bottom center of this room is a closed cubicle. Use the bridge to enter that area and collect the "dot". Carry this item to the screen just above the catacombs, located one screen down and to the right of the Gold Castle. Note: The "dot" is the same color as the ground outside, so care must be taken not to lose it in transit. Drop the "dot" here, and bring two other items onto the same screen. Move through the line on the right side of the screen to view the programmer credits.

Press Select immediately after ending the game to hear the ending music played very slowly.

Walk over title screen:
