Emerald Battle Videos At first glance, battle videos don't appear to have any useful purpose, other than for entertainment. However, a video can be used to save and restore a specific PRNG value. Using a battle video allows cart players to reach frames that were once thought to be out of reach, as one can advance to a very high frame and save a value within quick reach of the target frame. How it works When you enter a battle in the Battle Frontier, as soon as the screen fades to black, that PRNG value is stored. To save the video, you must win or lose the battle—quitting doesn't allow you to save. When you view the battle video, the PRNG doesn't advance at all (not even the normal advance every frame). The value remains unchanged until the first turn begins to play out. To find out the PRNG value stored in the video, simply use EonTimer set at a low frame like 1000, start the timer at the same time you press B to exit the video, and encounter a Pokemon when the timer runs out. A stationary Pokemon Pokemon would be ideal, as it's easier to find out what frame you hit. Determine the frame you landed on, subtract that value from your target frame, and add that to the value in EonTimer. Tips/misc. info The RNG advances twice as fast when you're in a battle (except in the Battle Frontier, where the RNG doesn't advance at all except for battle calculations). Combine this with battle videos to advance to high frames even faster. By using multiple battle videos, one doesn't have to leave the game on for one continuous period of time. Save after saving a battle video, and then load it to continue to advance the RNG another time. It would be a good idea to test the PRNG value stored for each video made to keep track of the current frame. The only Pokemon that can't be RNG abused using battle videos are the starter, Castform, and the roaming Latias or Latios. Because the game resets after beating the Pokemon League, players can't take advantage of a different starting seed from starting a new game. Battle videos can be saved in any facility, except for the Battle Pike and Battle Pyramid.
