Here are some cheats and tips for the game Super Hydlide.
Hidden gold and sound test:
Game play starts in the City of the Forest. After speaking
to the townspeople, leave the town and enter into Fairie Land.
Move five screens to the left and enter a cave at this location.
You will discover a deserted village. Walk around the first
wooden fence and walk downward. Your character will walk onto
the brick wall. Continue to move to the left, onto the patch of
trees, and enter the middle clearing of trees. Press B
to collect 10,000 gold pieces. Enter the top left building to
find the sound test. Once inside, each of the game’s sound may
be heard.
Easy experience points:
Locate the pond in the City of the Woods. Stand on the left
side, at the bottom of the bridge. “Use” a coin, then
search the ground to collect 30 experience points.
Defeat the final Boss:
Kaizack will remain motionless after each of his arms has
been shot off. Enter his mouth while continuously firing. He may
be easily defeated if you have a large amount of hit points.
