Region option? (Problem from Dissidia Duodecim)

[Code101]

Is there some kind of region option we can change?
My Dissidia Duodecim (Europe) game seems to think that O is X and vice versa yet at the same time, it isnt like that for any other game and region is the only reason I can think of that would be the problem.
Even if region is not the problem, I still think adding a fake region setting would be a good idea, is it too early to add this feature or hasnt anyone thought about it yet? (I would do it myself but I dont know much about coding)
