This is a tool-assisted speedrun. For more information, see http://tasvideos.org/2092M.html Castle of Dragon, known as Dragon Unit (ドラゴンユニット) in Japan, is an obscure arcade game about a castle with a dragon in it. Perhaps it's not the most original sounding game; but it does have nudity, gratuitous violence, and Engrish to make up for it. The action is very fast paced, and with the help of TAS skills, the dragon master is dispatched quicker than a hard boiled egg. We also have a movie of the NES version (http://tasvideos.org/1698M.html) .
