: This is the primary technique for BDSP. Because the game's RNG advances based on character blinks, players use external software to track these blinks through a webcam or capture card to identify the current RNG state. Because the game's RNG advances based on character
In Pokémon Brilliant Diamond and Shining Pearl (BDSP), RNG manipulation is a technique used to predict and influence the game's internal random number generator to obtain specific outcomes, such as , perfect Individual Values (IVs) , or specific natures . Unlike hacking or using external save editors, this method involves monitoring in-game events—specifically the player character's blinking pattern —to determine the game's current "seed" and target a precise "frame" for an encounter.
