Famicom Mini: Nazo no Murasame-jou is a Game Boy Advance video game released in 2004 by Nintendo. It is a remake of the Famicom game The Mysterious Murasame Castle, and little to no alterations were made on the game to stay faithful to the original title. The game was not released in America or Europe, and thus was exclusive to Japan. It was part of the Famicom Mini Series that re-released a variety of classic Famicom games for the Game Boy Advance.
