GAMECONTROLLERCONFIG

A variable that lets you manually hint extra gamecontroller db entries

The variable should be newline delimited rows of gamecontroller config data, see SDL_gamecontroller.h

This hint must be set before calling SDL_Init (SDL_INIT_GAMECONTROLLER) You can update mappings after the system is initialized with SDL_GameControllerMappingForGUID () and SDL_GameControllerAddMapping ()
