Stronghold of the Dwarven Lords

Deep in a 15 by 15 cavern lies the Dwarven gold, in one of three places: the north-east, north-west or south-east corner. You start in the south-west, and your only clue is the Dwarven Source Beam, which after each step reads 100 times the north-south distance to the gold plus 10 times the east-west distance. Find the gold in as few steps as you can. The map shows the cavern and where you are, never the gold; you see it once for free at the start, and every later look costs 15 steps. The cavern is built as in the book, from its fixed passages plus a fifth of the other squares opened at random, and the gold's place is chosen at random.

The book printed your surroundings as text and suggested turning them into a 3D maze; this version does that, with a first-person view and the four directions still listed beside it. Because you now face a direction, turning is new, and free. The book's data opened only 68 of its 69 passage squares, leaving out the north-east gold's own square; all 69 are opened here so the gold can always be reached. The gold shows in the view when it is straight ahead, the end map shows where it was, and the best (lowest) number of steps is kept. New music (Under the Mountain) and sound effects are added.

Controls: either joystick. Up steps forward, down steps back, left and right turn. Either button looks at the map (15 steps). The keypad is not used.
