In the Japanese version, the title screen will show an animation of Kirby popping out of the hole while the stars shown change color. In the International release of the game this is replaced with a stationary Kirby on a blue and starry background, with spotlights moving around on the title screen.

There is an unused mix ability icon in the game's data which was probably going to be used in 2-player mode if someone bumped into the mix ability enemy but was cut for unknown reasons.

The Japanese version has an animated introduction that is absent from the international releases of the game, where the story was relegated to the instruction manual, this was cut along with the soundtrack to the intro, several test courses and the debug menu.

This was done to lower production costs, by cutting down the size of the ROM it could be fit onto a cheaper cartridge for the international release.

Kirby's Dream Course contains many sound effects from Earthbound, as both games were developed side by side.

Originally, Kirby's Dream Course was not going to be a Kirby game. It was originally a game titled Special Tee Shot, a miniature golf game which was going to be released on the Super Nintendo. It was midway through development before the game was reworked using elements from the Kirby series. Special Tee shot eventually got a release of its own on the Satiliteview add-on for the Super Famicom in Japan.

The color palette for the buttons on the SNES controller was changed in the North Amercian version to show the colors that are on the controller in North Amercia. The PAL version keeps the button colors from the Japanese version, but removes the text.
