From http://www.hardcoregaming101.net/korea/part1/company-topia.htm:
For their last Action-RPG before they withdrawed from the game business, Topia returned to the MSX, this time creating one of the country's few MSX2 games. Future Boy Conan is based on the Japanese animated series with the same title, but its licensing status is rather doubtful. Just as Pungnyu Hyeopgaek, advertisements and short magazine reviews are all that is passed down about the game.
