The MSX version was never released outside Japan. Confusingly in the West on other platforms, this is called simply "Genghis Khan", while in Japan it is the second in the series, and sometimes called "Genghis Khan 2" although the third release in the series is called that in the West.
The Japanese title translates to "The Blue Wolf and The White Doe - Genghis Khan" though Doe is often misgendered as Stag.
Note: There is both an MSX1 and an MSX2 edition of this game
