I have to spend some time going over my notes and seeing what I had planned for axis remapping… especially in the presence of multiple joysticks. It seems likely that I just never finished this piece. I will take a look… maybe this weekend if not sooner.
Lemur’s InputMapper (which will someday be a part of JME), is already supposed to allow remapping of this sort of thing.
Note: the constants in things like JoystickAxis are meant to map to the standard things that the joystick will report. I don’t believe that changes across countries. So I guess you mean mapping them into local-friendly names for display to the user.
