Dark Castle looks like a Genesis version of Donkey Kong. This new movie by Aqfaq is one second faster than his previous version.

I managed to skip most of the game, which is good because Dark Castle sucks.
This is a tool-assisted speedrun, made on an emulator, using frame-by-frame shooting, savestates, and rerecords to overcome reaction time and human error. As such, it is purely a form of entertainment, and is not designed to show skill.
