Mouse preferring touch screen

I hope I can get some help on this one- I am using this airmouse- http://a.co/d/fUq0kuA for light gun games such as duck hunt. It works okay but the cross hair isn’t following the cursor. I set Grab Mouse to Page_Up but it doesn’t help.

I don’t know how to program but I think it’s this thing - ENABLE_TOUCH_SCREEN_MOUSE - in this file - https://github.com/libretro/RetroArch/blob/master/input/drivers/android_input.c that is making it want to use touch mouse instead of the cursor.

I would really love some help on this and If I need to add a Git Hub Request, let me know.
