RetroArch CLILink

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.

Note: please be aware of whether your system uses DOS/Windows style paths with backslashes \ or Unix-style paths with forward slashes: /.

Loading a ROM and libretro core (Unix-style path)Link

retroarch -L /path/to/libretro/ game.rom

Verbose logging outputLink

To get a better idea on what's going on, use the --verbose flag. If you want to report a bug, it is vital that this log is included.

Using a config fileLink

By default, RetroArch looks for a config in various places depending on OS:

  • Linux/OSX: $XDG_CONFIG_HOME/retroarch/retroarch.cfg, then ~/.config/retroarch/retroarch.cfg, then ~/.retroarch.cfg, and finally, as a fallback, /etc/retroarch.cfg.
  • Windows: retroarch.cfg in same folder as retroarch.exe, then %APPDATA%\retroarch.cfg.

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 --menu as well if you aren't loading content directly from the command-line, or RetroArch will close immediately after launching. See man-page and/or --help for detail.
