Reply To: Cannot, for the life of me, figure out how to set controls

It’s defined by the way the emulator executable is called (check the es_systems.cfg). For retroarch it loads the retroarch.cfg in the corresponding system folder. That retroarch.cfg includes the one in configs/all. So if you want to overwrite the button layout you can do it in the system specific config folder. The system specific config also has the variable input_remapping_directory which defines a folder with a new config cfg.

If you want to do it for every retroarch core you can change the auto config file for your controller. Changing the retroarch.cfg in configs/all with a new button layout did nothing for me while the autoconfig was enabled.
