I guess we have a problem with how Batocera is handling the button mapping. When I try to setup a gamepad button, it is just states that this button is already mapped. It makes no sense to me, I'm trying to change the button mapping, I need to change it becouse it's not really mapped or mapped to an undesired button. So I guess it would be better if it just replaced the button mapping to the one I'm telling it to, and unmap this button from whatever it was before.
