SDL_HINT_JOYSTICK_HIDAPI_GAMECUBE


brief A variable controlling whether "low_frequency_rumble" and "high_frequency_rumble" is used to implement
the GameCube controller's 3 rumble modes, Stop(0), Rumble(1), and StopHard(2)
this is useful for applications that need full compatibility for things like ADSR envelopes.
Stop is implemented by setting "low_frequency_rumble" to "0" and "high_frequency_rumble" ">0"
Rumble is both at any arbitrary value,
StopHard is implemented by setting both "low_frequency_rumble" and "high_frequency_rumble" to "0"

This variable can be set to the following values:
"0" - Normal rumble behavior is behavior is used (default)
"1" - Proper GameCube controller rumble behavior is used

This variable can be set to the following values:
"0" - HIDAPI driver is not used
"1" - HIDAPI driver is used

The default is the value of SDL_HINT_JOYSTICK_HIDAPI on macOS, and "0" on other platforms.

It is not possible to use this driver on Windows, due to limitations in the default drivers
installed. See https://github.com/ViGEm/DsHidMini for an alternative driver on Windows.

SDL_HINT_JOYSTICK_HIDAPI_PS3

SDL_HINT_JOYSTICK_HIDAPI_PS4


brief A variable controlling whether extended input reports should be used for PS4 controllers when using the HIDAPI driver.

This variable can be set to the following values:
"0" - extended reports are not enabled (the default)
"1" - extended reports

Extended input reports allow rumble on Bluetooth PS4 controllers, but
break DirectInput handling for applications that don't use SDL.

Once extended reports are enabled, they can not be disabled without
power cycling the controller.

For compatibility with applications written for versions of SDL prior
to the introduction of PS5 controller support, this value will also
control the state of extended reports on PS5 controllers when the
SDL_HINT_HIDAPI_PS5_RUMBLE hint is not explicitly set.

SDL_HINT_JOYSTICK_HIDAPI_PS4_RUMBLE


brief A variable controlling whether the HIDAPI driver for PS5 controllers should be used.

"0" - HIDAPI driver is not used
"1" - HIDAPI driver is used

The default is the value ofHIDAPI

SDL_HINT_JOYSTICK_HIDAPI_PS5


brief A variable controlling whether the player LEDs should be lit to indicate which player is associated with a PS5 controller.

"0" - player LEDs are not enabled
"1" - player LEDs are enabled (the default)

SDL_HINT_JOYSTICK_HIDAPI_PS5_PLAYER_LED


brief A variable controlling whether extended input reports should be used for PS5 controllers when using the HIDAPI driver.

This variable can be set to the following values:
"0" - extended reports are not enabled (the default)
"1" - extended reports

Extended input reports allow rumble on Bluetooth PS5 controllers, but
break DirectInput handling for applications that don't use SDL.

Once extended reports are enabled, they can not be disabled without
power cycling the controller.

For compatibility with applications written for versions of SDL prior
to the introduction of PS5 controller support, this value defaults to
the value ofHIDAPI_PS4_RUMBLE.
