Command Line Options

Dolphin includes a variety of command line options that may be useful for scripts, development, or debugging. Basic help and usage for them can be shown by running "Dolphin --help". The options are as follows:

-h, --help                                    Show this help message
-d, --debugger                                Opens the debugger
-l, --logger                                  Opens the logger
-e, --exec=<str>                              Loads a specific game file (ELF, DOL, GCM, ISO, WBFS, CISO, GCZ, WAD)
-n, --nand_title=<str>                        Launch a NAND title
-b, --batch                                   Exit Dolphin with emulator
-c, --confirm                                 Set "Confirm on Stop".
-v, --video_backend=<str>                     Specifies a video backend to use, D3D or OGL.
-a, --audio_emulation=<str>                   Specified the type of audio to use, HLE or LLE.
-m, --movie=<str>                             Plays a movie file
-u, --user=<str>                              Specifies a path to the user directory
-C, --config=<System>.<Section>.<Key>=<Value> Set a configuration option.

A shortcut file on Windows can be customized with command line arguments to a specific Dolphin build. First create a shortcut to the executable of the Dolphin build desired, then open the shortcut's properties and edit the target field. After the path to dolphin, add an argument like --logger, then save. Using --logger as an example, the shortcut will then launch the Dolphin with its logger window opened. The -u option will override the portable.txt file. The --help option is a CLI message, only command line window can view it.

Dolphin will check if that file exists in the same directory, then it will not use the default user directory; instead, it will create a \User\ folder in the same directory as the executable.
