I cannot get the C-Down button to work on my Generic Usb Joystick in Mupen64 because C-down is listed as Joystick 2 - Down. I cannot set a value for Joystick 2 - Down when configuring my controller in Batocera, as it only gives me the options to set values for Joystick 2 - Up and Joystick 2 - Left.
The file i'm referring to for the configuration is \batocera\share\system\configs\mupen64\input.xml
Is there a way to manually set a value for Joystick 2 - Down or to change the button that corresponds with C-down?
Hopefully this makes sense.
