Start a new game, and enter "SPELUNKER" as a name. This mode has
alternate dialogue, death with one hit, and the death sound from the
original Spelunker. Alternately, while playing the game in From mode,
you may encounter a Spelunker trapped in an area at the top-left corner
of the map. Use the flame wand on the stump to the right of him to free
him and unlock Spelunker mode in a new game.
