Hi 
 
	I'm not sure if I'm missing a setting or if this is actually possible.
 
	I'm using a Ipac-4 ultimate and I have all my key bindings configured in RetroArch.  This is all working properly.
 
	Now, I want to make a few changes specific to the different cores / systems that I'm using.  When I load a core all my mapped buttons are correct.  I want to change / move some of the functions to other mapped controllers. 
 
	So, for example.  In stella, Atari 2600.  I want to change the mapping for "right difficulty A"  & "right difficulty B" switches.  I can only set this option for controller #1.  I would really like to map this to controller #2, but it is not listed in the options, for controller 2
