>>39757735Not that guy, but I do egg RNG. The way that shiny generation is that every trainer has a TSV (Trainer Shiny Value) and every pokemon has a PSV (Pokemon Shiny Value). When talking about eggs, we call the PSV Egg Shiny Value (ESV). When generating the pokemon, the game checks if TSV and PSV are equal, and if they are the pokemon is generated as a shiny
First of all, you need to know your egg seed and your TSV, and there are ways to find it. You can think of the egg seed as a "status" in a given time. The main difference between egg seed and the seed for wild pokemon is that egg seed ONLY changes when an egg is accepted or rejected, whereas wild seed (or main seed) changes every frame the game is in the overworld and is influenced by other factors.
If you know your egg seed and your TSV, you can input that data in a tool, and provided the info on the parents, you can see every egg in the future using those parents.
After that, it's a matter of setting your target, and then trying to accept the correct egg. Every accepted egg advances the egg seed by a certain number, and every rejected egg advances the egg seed by 1 frame. You can think of accepting eggs as taking big steps in the list, and rejecting eggs as small steps. In the end, you end up accepting N eggs and rejecting M eggs, and the one you accept next is the egg you wanted.
The only problem with this method is that you end up with tons of eggs in your boxes that you can't free until they hatch, but since you know which eggs you accepted, you know their ESV, and that means that you can find someone online who matches the ESV and can hatch that egg as a shiny
Stationary RNG involves a timer and you hitting A at the correct time. That's all I know about it
