There has been a lot of unreleased SNES games that have come out this year, and this is likely the biggest yet. Special Tee Shot was the unreleased predecessor of Kirby's Dream Course, and was supposed to be released in 1992. A version of the game did come out on the Satellaview, but it is quite different from the prototype. Enjoy!
Special Tee Shot was going to be an early SNES release by HAL. Eventually it was remade into Kirby's Dream Course. The game also eventually came out on the Satellaview, but differs in many ways.
