How to switch a US save file to a PAL save ?

[Turaltay]

I am from germany and wanted to ask the same question. It is possible to add and change Pokemon with PKHeX. But this seems to be only possible if there is already a custom pass in the savegame. Is it possible to create a custom pass without a DS on Dolphin or modify the savegame to enable it? Unfortunately all savegames in the internet are english and i would like to use my own profile name.
