List of Super Princess Peach pre-release and unused content

This is a list of beta elements for the game Super Princess Peach.

Early builds
A very early screenshot shows a very early version of the "Peach's face" screen, which ended up on the bottom screen, to be on the top screen and totally devoid of Heart Panels and also having a bright green, solid background and a different design for Peach. Since Heart Panels, which were used to change Vibes in the final game, are lacking from this screenshot, this suggests that Super Princess Peach was once planned to not use Vibes and be a more average side-scroller.

Unused data
The Koopalings were originally going to be in the game, but were taken out for unknown reasons. All of the Koopalings' sprites have been discovered. Roy was given a green shell instead of a pink shell. This may have been either a design change or a mistake.

Sprites of Glad and Calm Goombas have also been discovered. In the game, only Mad and Sad variants appeared. The Glad Goomba (which was a bronze or yellow color), based on its sprite, could be able to bounce or dance around (as the glossary says most Glad Enemies do), and the Calm one (which was green and rather sickly-looking), based on the Calm Enemies, would probably be sleeping and act like a normal Goomba when Peach is too fast.

There are also flying sprites for a regular Goonie in the game data. There are no sprites, however, of it being damaged and returning to a Flightless Goonie. The sprites are directly from Yoshi's Island: Super Mario Advance 3, with the sole difference being the palette darkened to resemble Super Princess Peach. There is also a Chomp Rock in the game data, as well as unused background graphics resembling the ones in Yoshi's Island: Super Mario Advance 3.

Located in the depths of the game are also sprites of Peach in different art styles, supposedly from when the development team were deciding on an art style. Some of these early sprites of Peach are even used in the pre-release screenshots.
