Its not hard, just go in and change the text, if they did it the right way. Similar to editing posts here. Like I said assuming it was done the right way.
I get what you mean, though, a controller is immensely helpful to playing the game (again, from what I have read, as I have the 360 version).
I have a controller. It's not an Xbox controller though, as I don't need one, I'm happy with my current controller... but it doesn't have a button A, or a button Y! Or whatever else the xbox one has. >:(
