The original Castlevania is set in the year 1691. Simon Belmont must fight his way through the castle and destroy Count Dracula.
Challenger ( https://tasvideos.org/Users/Profile/Challenger ) and eien86 ( https://tasvideos.org/Users/Profile/eien86 ) improve the predecessor movie ( https://tasvideos.org/4342M ) by 00:06.79 seconds, thanks to better optimization of the scroll glitch as well as more clever ways of utilizing it.
There is also a run of this game which destroys as little as possible ( https://tasvideos.org/4371M ).
The MSX version ( https://tasvideos.org/2444M ) has been TASed as well!
