How do I configure mouse movement and right and left clicka in retroarch input?

Hey there so I decided today it would be best for me to also configure retroarch for keyboard controls instead of just use with my controller. Anyways I am trying to setup the input settings to use my mouse movement for the right stick and the left and right clicks to be used for right and left trigger. I don’t understand how to actually accomplish this. I go into input settings and select what I want to edit but moving my mouse or clicking doesn’t register anything in the input settings. What do I need to do to accomplish this?

I am currently using the Retroarch April 30th nightly build.

RetroArch doesn’t support that. You would have to find some other program that translates mouse movement to analog joystick input and then map that into RetroArch.

Well that definitely explains why I could not find the option. That is my suggestion then. For now I’ll try to see if maybe the numpad works. Thanks for your response.
