A hidden feature in these Pokémon games is the ability to tell a certain NPC four specific words or phrases using the easy chat system in order to unlock special rewards. Which words are required are unique per save file.
In Diamond, Pearl, and Platinum these rewards include 8 different special PC box wallpapers. The NPC to speak to is located on the 3rd floor of the Jubilife TV station.
In HeartGold and SoulSilver, rewards include 8 different PC box wallpapers plus 3 different Pokémon eggs. The NPC to speak to is located in the Violet City Pokémon Center.

The original distribution of these passwords was via the Pokémon Daisuki Club, a defunct, Japanese-exclusive official fan club website.
Below is both a calculator to generate the passwords for your specific save file, an in-depth explanation of how the password check system functions, and a full dump of the relevant word data.

One thread caught his eye.

Rohan’s mind wandered back to the night his younger brother, Arjun, had asked him to watch a Bollywood classic with him. That memory reminded Rohan of why he loved movies: the shared experience, the emotional ride, the conversations that followed. He realized that by supporting the creators—by paying for the film, however small the amount—he was keeping that chain alive. Rohan’s curiosity got the better of him
Halfway through, the film’s climax arrived. A chilling revelation that tied together all the ominous symbols he’d seen on the screen. Rohan’s heart pounded, his palms were slick with sweat. When the final credits rolled, a silence settled in his tiny room, broken only by the distant rumble of thunder. It was a post from a user called
The next morning, Rohan called Arjun and told him about the movie, describing the plot twists and the haunting soundtrack.

Yet the satisfaction of enjoying art through the right channels, respecting the creators, and supporting the ecosystem that brings stories to life is a reward far richer than any fleeting thrill of piracy. The next time you’re tempted by a mysterious file name like Sinister.2012.Hindi.ORG.Dual.Audio… , pause, consider the impact, and choose the path that lets the story shine—legally and proudly.
