Galleon: Islands of Mystery

Enter Areliano's house. It contains three empty bedrooms and
a fourth guest room to which you are taken. You must open the
doors into these rooms from the corridor in a particular order
to enable cheat mode. Opening the doors from the room side will
not count -- you must be standing on the corridor side. There
are three doors in the corridor, with the third door being the
closest to Rhama's room. Open the first door three times, the
second door six times, and the third door nine times (in order).
If you make a mistake, you must start again. If done correctly,
the final Boss' sword will appear on your character's back and
you will have 99 pistols in your inventory. Additionally, when
you complete the game, all ending credit bonuses will be unlocked.
The pistols will disappear when you proceed to the next level.
Collecting all of an item after the code is enabled has the
opposite effect and will negate that bonus in the ending sequence.

Secret Sword:
The secret sword is available after Jabez's betrayal. Once you reach
his ship you will once again be able to run about the island. Go to
the shop with the cannon outside. Jump on the cannon then into the
open window. Inside, you'll find the secret sword in a box.
