Bug ID: 51908
           Summary: Make evdev joystick axis mapping customizable.
           Product: Wine
           Version: 6.19
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P2
         Component: directx-dinput
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

The legacy dinput joystick backends previously supported some custom mapping
from the registry, and it's now gone.

SDL supports axis mapping customization through its game controller mapping
(although it then exposes an abstracted game controller device), and hidraw and
iokit are just raw pass-through backends, but Wine evdev axis to HID usage
mapping could be made customizable to better support exotic or bogus joysticks.
