Released in 1997 on PlayStation and Sega Saturn, Daikoukai Jidai Gaiden uses the same engine as the Uncharted Waters: New Horizons (known as Daikoukai Jidai II in Japan), and focuses on the story of two characters instead, further expounding upon the loose plot that ties the series together. The two protagonists are as follows:

-Miranda Verte: Genoese adventurer who mistakenly thought the treasure hunter, Pietro Conti, had asked for her hand in marriage, and sets off to find him. Her quest eventually leads to a plot relating to an ancient civilization in South America, which were touched on by Pietro's previous adventure.

-Salvador Reis: Pirate and adopted son of Hayreddin Reis (aka Khayr ad-Din). His adventure involves rising to fame as one of the Algerian pirates, compete for domination with enemy pirate clans and also struggle for power within his own clan.
