F1 2016 XBox buttons location

[Clemens]

Hello, I would like to have PS button images instead of XBox button images.

Is there a mod out for this yet?

If not does someone know if they are stored in a certain location? (or hardcoded ) ?
If so where is it?

I've searched a bit but nothing found yet...would like to make a mod for it if there isn't one out yet, but without the location I can't really start....

Thanks a lot...
