Unlock bonus:
Successfully complete the game to unlock the survival mode and level select
options.
Unlock alternate ending sequence:
Collect all the treasures and secret swords during game play to get an
alternate ending sequence.
Cheat mode:
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. Note: 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
