RetroArch can be utilized via its robust graphical interfaces as well as a powerful command-line interface (CLI). Getting familiar with the command-line helps you understand the design principles of RetroArch.

To override this, use
retroarch --config customconfig.cfg. If you have some special options you want to store in separate config files, you can use
retroarch --config baseconfig.cfg --appendconfig specialconfig.cfg. Be sure to pass
