Pokémon Diamond and Pearl demo

The Pokémon Diamond and Pearl demo was available in select video game retail locations in western countries in early 2007.

In the demo, the player controls the female character in Diamond, and the male character in Pearl, named "Diamond" and "Pearl", respectively. The player begins in Jubilife City, and Barry will give them a tour, during which the player has no control. At the end, Barry will drop the player off at the entrance to Route 203.

The player is given no items, and only the Pokémon of Lucario (Force Palm, Me First, Bone Rush, Metal Sound), Roselia (Leech Seed, Magical Leaf, GrassWhistle, Poison Sting), and Mime Jr. (Barrier, Copycat, Mimic, Psybeam), each at Level 30. The menu is modified to only include the "Pokémon" menu and no other options. The player is equipped with Running Shoes.

Upon taking a step onto Route 203, a scientist will approach the player and give them a Pokétch, though it contains only the digital watch app and no other apps.

The player is then free to explore Route 203, though it is modified from the final version of the route that is in the full version of the game. Specifically, obstacles have been added to prevent the player from accessing the tall grass and encountering wild Pokémon. Three trainers stand in the way of the player, which the player may either fight or avoid: Youngster Roland (who uses a Level 23 Buizel and a Level 23 Mantyke), Lass Carrie (who uses a Level 23 Chatot and a Level 24 Pachirisu), and Youngster Norman (who uses a Level 24 Kricketot and a Level 25 Cherrim).

Upon reaching the end of Route 203, the player meets with Professor Rowan, and may speak with him to cause him to instantly evolve the player's Roselia into Roserade, with Rowan commenting that several Pokémon are able to evolve in the Sinnoh region that were previously thought to be unable to evolve.

The cave at the end of the route (which leads to Oreburgh Gate in the final version of the game) is blocked by Lucas/Dawn. If the player speaks with them, Lucas/Dawn will tell the player that they look forward to seeing them in the full version of the game, and then the demo ends and the game resets back to the title screen.

If the player blacks out at any point, the demo ends prematurely, also resetting back to the title screen.
