Knightmare

Knightmare, known in Japan as Majou Densetsu (魔城伝説 , Demon Castle Legend?), is a 1986 MSX vertical scrolling shooter computer game. The player is a knight, Popolon, who must fight his way through several levels to defeat Hudnos and rescue Aphrodite. Knightmare was an innovative top-scrolling shoot 'em up game for the MSX system, released as a game cartridge. The top view graphics were considered very sophisticated for the time, similar to other MSX games like Nemesis and Penguin Adventure. Konami also released a slightly modified version that could be purchased through the LINKS network. (Japanese "internet replacement" of the 80's) In this version you could submit your high scores to an online server. It was brought to SG-1000 in Taiwan without a license.
