Sets the configuration file path. \fBretroarch\fR will use this path to load the configuration file.
Should this not be defined, \fBretroarch\fR will look in platform specific paths to attempt finding the config file.
/etc/retroarch.cfg (when installed), or retroarch.cfg in the source tarball serves as a skeleton configuration file.
/etc/retroarch.cfg should serve as a skeleton config only, and not used as a config file.
/etc/retroarch.cfg should serve as a skeleton config only.

Unix-like systems will look in $XDG_CONFIG_HOME/retroarch/retroarch.cfg first. If $XDG_CONFIG_HOME is not defined, it is assumed to be $HOME/.config as per specification. Then it will try $HOME/.retroarch.cfg. If both paths fail, RetroArch will try to create a new, default config file in $XDG_CONFIG_HOME/retroarch/retroarch.cfg (or the $HOME/.config default for $XDG_CONFIG_HOME). If no configuration is found at all, default settings will be assumed.
RetroArch will not attempt to load the skeleton config /etc/retroarch.cfg.

If all fails, default settings will be assumed.
If RetroArch creates a new default config file, it will attempt to load the skeleton config file /etc/retroarch.cfg and use that as a basis.
This allows distributions to set up default paths for libretro cores, and similar things.
A configuration file does not need to define every possible option, only those which should be overridden.
If config_save_on_exit = true is set in the config file, RetroArch will overwrite the config file on exit. Settings can be changed from within RGUI.
