Deadzone right analog stick

[pmroyo]

Good morning everyone

I am having an issue with my gamepad when playing N64 games. As most of people, I use the right analog stick as C buttons. The problem is that the sensibility of this stick is very high and sometimes it works by its own. I have been trying to change the deadzone parameter in input.xml file, but the line:
<input name="AnalogDeadzone" value="4000,4000" />
only refers to X and Y axis of the left analog stick.
Is there any option to add another line for the right analog stick? any other solution

Thank you in advance
