# User Handbook - Command Line

There are two main applications, an SDL-based app (`eden-cli`) and a Qt based app (`eden`); both accept command line arguments.

## eden

- `./eden <path>`: Running with a single argument and nothing else, will make the emulator look for the given file and load it, this behaviour is similar to `eden-cli`; allows dragging and dropping games into the application.
- `-g <path>`: Alternate way to specify what to load, overrides. However let it be noted that arguments that use `-` will be treated as options/ignored, if your game, for some reason, starts with `-`, in order to safely handle it you may need to specify it as an argument.
- `-f`: Use fullscreen.
- `-u <number>`: Select the index of the user to load as.
- `-input-profile <name>`: Specifies input profile name to use (for player #0 only).
- `-qlaunch`: Launch QLaunch.
- `-hlaunch`: Launch homebrew launcher `nx-hbloader`.
    - Requires a copy of Atmosphere to be extracted onto `sdmc`.
    - This is a shorthand for `<eden folder>/sdmc/atmosphere/hbl.nsp`.
- `-setup`: Launch setup applet.
