To perform this exploit, reach an RNG seed that occurs before a target value, enter a battle in any of the Battle Frontier facilities, either win or lose, and then save the Battle Video. Forfeiting by selecting "Run" does not allow this option. When the game is next saved, the Battle Video and its corresponding initial seed will be saved along with it, so whenever it is viewed, the RNG will be advanced to a handful of frames after that seed. The lack of idle RNG advancement in battle while in the Frontier makes the difference between the two significantly less than in most other cases.
