Now that the RNG Seed is known, the Shiny Frame can be determined.
1. Load up Display Raids of the plugin on PKHeX
2. Load up Raid Calculator.
3. Now input the found RNG Seed, and set shiny to Yes (Any Type). Lastly, hit Search
Den, Species and IVs can be ignored for now. We just want to know where is the shiny frame.
4. Shiny Frame found!
In my case, it is 1094 frames away. If you intend to SR species (I intend to), I need to advance my game till 3 frames away.
Typically, I advise you to restart (from wanted light) if your frame is larger than 1000.
Alternatively, if you have a backed up save, you can know your shiny frame by simply loading up Display Raids (to bring up the Raid List) for that save,
and going to the Den ID:
