// Sets device to be used for player 'port'. // By default, RETRO_DEVICE_JOYPAD is assumed to be plugged into all // available ports. // Setting a particular device type is not a guarantee that libretro cores // will only poll input based on that particular device type. It is only a // hint to the libretro core when a core cannot automatically detect the // appropriate input device type on its own. It is also relevant when a // core can change its behavior depending on device type.
// As part of the core's implementation of retro_set_controller_port_device, // the core should call RETRO_ENVIRONMENT_SET_INPUT_DESCRIPTORS to notify the // frontend if the descriptions for any controls have changed as a // result of changing the device type.

// Resets the current game. RETRO_API void retro_reset(void);
// Returns the amount of data the implementation requires to serialize // internal state (save states). // Between calls to retro_load_game() and retro_unload_game(), the // returned size is never allowed to be larger than a previous returned // value, to ensure that the frontend can allocate a save state buffer once. RETRO_API size_t retro_serialize_size(void);
// Serializes internal state. If failed, or size is lower than // retro_serialize_size(), it should return false, true otherwise. RETRO_API bool retro_serialize(void data, size_t size); RETRO_API bool retro_unserialize(const void data, size_t size);
