Hi,
so according to TCRF there are 2 unused Static Encounter in XY: a Scatterbug and a Abomasnow.
Speaking about a way to get it with @BlackShark I thaught we can use the same method as I did for GS Unused Venomoth slot.
But for that we need first to know where those 2 unused encounters are located.
What to do?
Modify a Static Encounter in XY with PK3DS and check the differences with an HexEditor.
Look around if there is the Scatterbug and Abomasnow slot and then swap them with Mewtwo for example.
Any volunteer?
I tried to do this but with my Gateway O3DS I failed using PK3DS.
I'll do some researches too in order to know more about those 2 Pokemon.
