• File src/hid/OHXInputGamepad.m — part of check-in [48e6a99f7b] at 2024-06-08 22:16:16 on branch trunk — OHEvdevGamepad: Filter buttons/axes

  This is instead of replacing them altogether, which means the button
  names are kept and extra buttons are not removed. (user: js, size: 5147) [annotate] [blame] [check-ins using]
