Vivillon Forms explained once for all in details?

[ranqt]

Wi the the last PKHeX upate, some Vivillon have been marked as illegal

I asked this on the wrong thread so they told me to write in this section.

Basically this (the attached image).
Only 3 of 20 forms had to be changed I really don't understand how this works. Any help/explanation?

Thank you

Start your game with 3DS region -> Turkey, Russia, for example.

Then save the game. This locks in Vivillon pattern.

Then, change the 3DS region to Poland to collect your egg, all the eggs will say Poland.
(This also works for any future encountered Scatterbug/Spewpa/Vivillon)

These region changing shenanigans only apply to region allowed in your 3DS legitimately.

So for example, you can't change to an EU device Country, if that country is not on your US device.


As for why your other Vivillon are marked illegal, I need to see them (in file form) before I can diagnose the problem
