The original Castlevania is set in the year 1691. Simon Belmont must fight his way through the castle and destroy Count Dracula.

Challenger improves one of the most well optimised runs on this site by 21 frames (roughly 0.35 seconds). However, due to the FPS difference between FCE Ultra (flat 60 FPS) and BizHawk (roughly 60.098 FPS), the improvement appears to be 1.47 seconds.

The MSX version has been TASed as well!

There is also a run of this game which destroys as little as possible.
