Model this part of the API after the Sony PlayStation 3 Controller which
exposes independent analog values for each one of the D-Pad buttons.
The PS3 programming API psl1ght also maps the analog D-Pad buttons
individually.

Hi,
as David mentioned no gamepad defines analog D-Pad buttons as mentioned in the
gamepad API, so the API change should be OK.
And is it OK too to fill the holes in the ABS space or should I just use
higher codes?
Thanks,
Antonio
