keys stores them differently, according to this:

typedef enum KEYPAD_BITS {
  KEY_A      = BIT(0),  //!< Keypad A button.
  KEY_B      = BIT(1),  //!< Keypad B button.
  KEY_SELECT = BIT(2),  //!< Keypad SELECT button.
  KEY_START  = BIT(3),  //!< Keypad START button.
  KEY_RIGHT  = BIT(4),  //!< Keypad RIGHT button.
  KEY_LEFT   = BIT(5),  //!< Keypad LEFT button.
  KEY_UP     = BIT(6),  //!< Keypad UP button.
  KEY_DOWN   = BIT(7),  //!< Keypad DOWN button.
  KEY_R      = BIT(8),  //!< Right shoulder button.
  KEY_L      = BIT(9),  //!< Left shoulder button.
  KEY_X      = BIT(10), //!< Keypad X button.
  KEY_Y      = BIT(11), //!< Keypad Y button.
  KEY_TOUCH  = BIT(12), //!< Touchscreen pendown.
  KEY_LID    = BIT(13)  //!< Lid state.
} KEYPAD_BITS;
