List of Mario Party 9 pre-release and unused content

This page pertains to the beta elements of Mario Party 9.

Stages
Toad Road had a much simpler design. One will notice that there are no Green Spaces or Mini Star/Mini Ztar Spaces, but there are instead Blue Spaces. Mini Stars and Mini Ztars were only seen to be in one number, rather than three, five and ten. The unbroken bridge seen in the image is broken in the final game, yet there are still spaces underneath the bridge; it is likely that the spaces on the bridge were event spaces that would cause the bridge to collapse if landed on. The vine is placed near the upper-left corner of the mountain instead of the spiral hill in front of the fort. A Lakitu is seen above the fort, possibly to symbolize the mid-boss of the fort is Lakitu. Additionally, on the final board, there are two rock formations on the tops of the mountains that form the letters "MP"; no such rock formations are seen on the beta board.

The center of the stage has a circular island that was later moved to the forest part of the stage in the final game, and was replaced with an island in the shape of a "9". It is unknown how to get there, although a Warp Cannon can be seen near a Lucky Space, indicating that the island (including the rocky mountain with a water slide) can be reached through the cannon. The Bowser Gate is not at the end of stage.

Lucky Space Routes
Peach takes a route that is not seen in the final game. Green Spaces are only seen here.

Minigames
A minigame involving two players attempting to capture Bowser Jr. in a mountain-like maze is not in the final game.

Spaces
Some spaces were left in the game's file but were never used. This includes a file that seems to be from early in the game's lifecycle. These spaces include a Blue Space, a red Back Space, a Lucky Space, a Dry Bones space, a Dice Block space, a Happening Space, a swirling space, a blue arrow space, a VS Space, a Bowser Space, a Shuffle Space, two hands coming together, a Star Space, a Ztar Space, and an orange space. The game stores all of these spaces in one big texture image.

There is another file that includes newer spaces that resemble the game's final spaces. The game stores a file for spaces that are big. Oddly, these spaces are very small. These spaces include a Red Space, a +3 Jackpot Space, a +5 Magma Space, a Stop Space (its filename is "stop"), a space with a lot of Ztars. The +10 Mini Stars Space and +10 Mini Ztars Space do have bigger variations, but were scaled down to fit in a single image.

Other
The HUD only displayed how many Mini Stars a player had, instead of a Dice Block. The characters' faces are also facing right, while in the final version they are facing forward. Spaces were also more brighter in color in the beta version. The Dice Block was designed a bit differently; it lacked the aesthetic effects of the final Dice Block.
