Usage: retroarch [OPTIONS]... [FILE]
  -h, --help            Show this help message.
  -v, --verbose         Verbose logging.
      --log-file FILE   Log messages to FILE.
      --version         Show version.
      --features        Prints available features compiled into program.
      --menu            Do not require content or libretro core to be loaded,
                        starts directly in menu. If no arguments are passed to
                        the program, it is equivalent to using --menu as only argument.
  -s, --save=PATH       Path for save files (*.srm).
  -S, --savestate=PATH  Path for the save state files (*.state).
  -f, --fullscreen      Start the program in fullscreen regardless of config settings.
  -c, --config=FILE     Path for config file.
		By default looks for config in $XDG_CONFIG_HOME/retroarch/retroarch.cfg,
		$HOME/.config/retroarch/retroarch.cfg,
		and $HOME/.retroarch.cfg.
		If a default config is not found, the program will attempt to create one based on the
		skeleton config (/etc/retroarch.cfg).

      --appendconfig=FILE
                        Extra config files are loaded in, and take priority over
                        config selected in -c (or default). Multiple configs are
                        delimited by '|'.
  -L, --libretro=FILE   Path to libretro implementation. Overrides any config setting.
      --subsystem=NAME  Use a subsystem of the libretro core. Multiple content
                        files are loaded as multiple arguments. If a content
                        file is skipped, use a blank ("") command line argument.
                        Content must be loaded in an order which depends on the
                        particular subsystem used. See verbose log output to learn
                        how a particular subsystem wants content to be loaded.

  -N, --nodevice=PORT
                        Disconnects controller device connected to PORT (1 to 16).
  -A, --dualanalog=PORT
                        Connect a DualAnalog controller to PORT (1 to 16).
  -d, --device=PORT:ID
                        Connect a generic device into PORT of the device (1 to 16).
                        Format is PORT:ID, where ID is a number corresponding to the particular device.
  -P, --bsvplay=FILE    Playback a BSV movie file.
  -R, --bsvrecord=FILE  Start recording a BSV movie file from the beginning.
      --eof-exit        Exit upon reaching the end of the BSV movie file.
  -M, --sram-mode=MODE  SRAM handling mode. MODE can be 'noload-nosave',
                        'noload-save', 'load-nosave' or 'load-save'.
                        Note: 'noload-save' implies that save files *WILL BE OVERWRITTEN*.
  -H, --host            Host netplay as user 1.
  -C, --connect=HOST    Connect to netplay server as user 2.
      --port=PORT       Port used to netplay. Default is 55435.
      --stateless       Use "stateless" mode for netplay
                        (requires a very fast network).
      --check-frames=NUMBER
                        Check frames when using netplay.
      --command         Sends a command over UDP to an already running program process.
      Available commands are listed if command is invalid.
      --nick=NICK       Picks a username (for use with netplay). Not mandatory.
  -r, --record=FILE     Path to record video file.
        Using .mkv extension is recommended.
      --recordconfig    Path to settings used during recording.
      --size=WIDTHxHEIGHT
                        Overrides output video size when recording.
  -U, --ups=FILE        Specifies path for UPS patch that will be applied to content.
      --bps=FILE        Specifies path for BPS patch that will be applied to content.
      --ips=FILE        Specifies path for IPS patch that will be applied to content.
      --no-patch        Disables all forms of content patching.
  -D, --detach          Detach program from the running console. Not relevant for all platforms.
      --max-frames=NUMBER
                        Runs for the specified number of frames, then exits.
