How does Roamer Editor in PKHEX actually work?

[nowhere]

Maybe I don't fully understand this but this option allows me to encounter a specific Pokemon right? Everything appears to be correct yet I can't find the Shiny Vulpix. It simply doesn't show up in game. Am I doing something wrong? I can't find much information anywhere about this.

For the context of your game, the roamers are Latias and Latios. Without knowing how exactly the game uses the values from the save file, it is unknown how it behaves for non-roamer species.
