This video is intended to be a demonstration of the battle video method, the method of shiny hunting that I used to find the three Johto starters in Emerald. I soft resetted over the shiny without saving in order to demonstrate that the shiny frame can be re-accessed by watching the live video and timing your presses perfectly.
This video is a very long one because of how monumental I see this shiny to be. I have now completed the set of Johto starters in 3rd gen, a task I previously viewed as impossible due to Emerald's broken RNG. When the speed running community came up with data on the battle video that indicated it could be used as a shiny hunting method, I jumped on the opportunity.
Now, almost a year after initiating the project, I have found all three Johto starters! I am just overjoyed to have these hunts completed, so I decided to put a bunch of effort into the video.
