This hack repurposes the life counter in Castlevania into a death counter. You begin the game with zero deaths, and each time you die the counter increases by 1 (up to 99). This effectively gives you infinite lives but more than just a simple cheat code, it also modifies the in-game UI to help players keep track of deaths and encourage trying to have as few deaths as possible.

[Changes]

• Repurposes the lives counter as a death counter.
• Death counter starts at 0.
• Dying increases the counter.
• Getting extra lives (either from points or the hidden 1up) plays the jingle but has no effect.
• Added a little skull icon to the UI to indicate deaths instead of lives.
• At 256 deaths the counter loops back to 99 to prevent a Game Over caused by an overflow.
