Pescatore is a prototype game for the NES, originally released in Japan. Its gameplay likely revolved around fishing, but specific details are hard to come by, given its unfinished status.  The English translation patch by KingMike v1.0 allowed more people to play this rare game. This is a classic example of an unreleased title that offers a glimpse into the experimental side of the NES game development scene.
