EDIT: It's possible make the masuda method?
The question arises because I do not think the game have a nationality and i read has to do with the region of the pc
Is that true?

FINAL EDIT:
thank you very much to everyone who gave me help, answered my questions and advise me to achieve my goals
if someone has a shiny lat me know and make an offer and I will try to fulfill to keep this
