So there is this big mystery between these two games.
Special Tee Shot (SNES / BS-X, 1996)

Kirby's Dream Course (SNES, 1994)

The graphics and music are different, but the gameplay concept is similar. Kirby's Dream Course also features an EAD programmer, 2 EAD map designers, and 2 EAD producers. Then it also states "originally designed by" two other EAD guys (Tatsuya Hishida and Shinya Takahashi).
It seems that Special Tee Shot was the original prototype mainly developed by the EAD Stunt Race FX team. It looks like Nintendo didn't see much sell factor, and asked HAL Laboratory to rework the title with Kirby in it. Is there anyone up to task of obtaining the credits from Special Tee Shot? I believe it can be played via emulator, and the credits appear after beating the pro course. It would be great for our Nintendo history archive.
