The original Castlevania is set in the year 1691. Simon Belmont
must fight his way through the castle and destroy Count Dracula.
Challenger and Morrison improve the previous TAS by 3.92 seconds, thanks to several new skips, different strategies for 2 bosses, and a better turnaround trick. Please read the authors' comments for more details.
The MSX version has been TASed as well!
There is also a run of this game which destroys as little as possible.
