Castlevania: Dracula X (1995), released in Japan as Akumajō Dracula XX, is actually a toned-down remake of a PC Engine title known as Rondo of Blood (1993). It stars Richter Belmont, supposedly a son of Juste Belmont from Harmony of Dissonance, on a mission to save Annette (said to be his girlfriend) and Maria Renard (a young vampire huntress said to be his girlfriend's sister), along with a number of their fellow villagers, from imprisonment by Dracula (said to be the villain) and his minions.
Unfortunately, in this SNES port Richter isn't too much of a fast walker - unlike his father and the later Belmont clan descendants - so his fastest way of moving is constant backflipping.
This run by McBobX aims to complete the game with the fastest completion route.
We also have a run of this game that accomplishes the best ending in the game.
