/etc/ssnes.cfg (when installed), or ssnes.cfg in the source tarball serves as a skeleton configuration file. /etc/ssnes.cfg (when installed), or ssnes.cfg in the source tarball serves as a skeleton configuration file.

Unix-like systems will look in $XDG_CONFIG_HOME/ssnes/ssnes.cfg first. Then it will try $HOME/.ssnes.cfg. Last, it will try /etc/ssnes.cfg. If no configuration is found, default settings will be assumed. A configuration file does not need to define every possible option, only those that should be overridden.
