Unused Contest Effect

Earn +2 for each
time the same Judge
is chosen.

しんさいんが
かぶるごとに＋２

Each doubled
Judge: +2

しんさいんが
かさなるごとに＋２

Effect 0x03 is a unique unused contest effect that is intended to increase appeal by two extra points every time the same judge is chosen. However, this function is incomplete and doesn't seem to work. It also comes with proper text and in-game descriptions.

Unseen Terrain Effects

The only marsh tiles that can be battled upon are located in the Great Marsh, where Pokémon moves can't be used, but the handful of moves that change based on the terrain type still have specific effects for marsh terrain coded in.

Move	Effect
Camouflage	Changes user's type to Ground
Nature Power	Becomes the move Mud Bomb
Secret Power	May lower the target's Speed by 1 stage; uses the animation of Mud Shot

This effect for Camouflage is shared with the used ones for sand and for plain terrain, but the other two are completely unique.

Unused Wild Held Item Data

Some Pokémon, when found in the wild, have a chance of holding an item. This held item data also exists for some Pokémon which cannot be caught in the wild in the final game, however, rendering these assignments unused.

Rotom, Giratina, and Shaymin Alternate Forme Placeholder Data

There exists placeholder data for alternate forms of Rotom, Giratina, and Shaymin in Diamond and Pearl, suggesting the alternate forms (sometimes referred to as "Formes") featured in Pokémon Platinum were already in development. There is a table within the game's coding that specifies the number of Formes/forms a Pokémon has. Pokémon that have no alternate forms are listed with the number 0, while Pokémon with alternate forms are listed with a number corresponding to the number of forms they have. For example, Pikachu has the number 0, while Deoxys has the number 4. There are three exceptions to this: Rotom, Giratina, and Shaymin are the only Pokémon listed with the number 1. It seems this number is meant to be a placeholder, indicating that at least one alternate form was planned or in development.

Unused Pal Park Species Data

When transferring Pokémon from Generation III games into Diamond and Pearl through the Pal Park feature, the location and appearance rate for each one as well as the score bonus for catching it are determined on a per-species basis. Every species in the game has unique data for this, including those that are newly-introduced to Generation IV and therefore cannot be encountered in Pal Park during normal gameplay.
