Daikōkai Jidai IV: Rota Nova

Daikoukai Jidai IV: Rota Nova is the port of Daikōkai Jidai IV: Porto Estado's PlayStation version. In comparison with its base game, this port contains a treasure hunting system based on treasure maps, much more profitable sea routes named "golden routes" and a new game mode that allows local multiplayers to do a sailing boat race with each other.

The DS version supports touch controls and was ported to smart devices later.
