Castlevania - Dracula X

Better ending:
Do not fall off the pillars on Level 3. Pick up the key that is located near the chamber of the headless knight. This key must be used on Level 4 to free Maria and open the path to the alternate Mission 5b. Note: The codes for Missions 6b and 7b follow this better ending path.

Extra lives:
A bonus life is awarded at the end of each level that is completed without your character getting any damage.
