Hat Trick 2020

Hat Trick 2020 (also known as Hat Trick: Four Player Mod and Hat Trick Extended) is a hacked version of Pacific Dataworks International's official C64 conversion of the arcade game of the same name. This hack adds the ability for up to four players to play, in teams of two, as opposed to two players only. This extended version hack was done by Barfly and released into the public domain on February 21, 2020.

Adding the extra players basically turns the game into an unofficial version of Team Hat Trick, which was a 4 player version released in arcade in 1985.
