A file browser and extractor for Smash Ultimate's data.arc file for Windows, MacOS, and Linux. The latest version of the program can be downloaded from releases. Report any bugs or request new features in issues.
Open an ARC file using File > Open ARC or Ctrl + O on the keyboard. The program supports any ARC file from Smash Ultimate version 4.0.0 (Hero DLC) or later. Use ArcCross (Windows only) for opening very old ARC versions.
The program also supports opening an ARC file over the network by connecting to the Switch console using the Switch's IP address. All program features work normally when connecting to the ARC file over the network but file extraction will likely be slower.
- Install Skyline if you haven't already
- Download the companion skyline plugin, arc-network and install it as you would any other skyline plugin
- Run Smash and keep it open
- Click File > Connect to ARC in ArcExplorer
- Input your Switch's IP address. This can be found under System Settings > Internet on the Switch itself.
- Click Connect
Navigating the ARC file can be done with the mouse or the keyboard. Double click a folder to open it. Click the "Exit Folder" button to exit the current folder and go the parent folder.
The textbox above the file list shows the current folder. Modify the path in the textbox to navigate directly to the desired folder. For example, copy paste fighter/mario/model/body/c00 into the textbox to avoid having to click fighter > mario > model > body > c00 individually.
Keyboard shortcuts are listed below.
| Action | Keys |
|---|---|
| Enter Selected Folder | Enter, Right Arrow |
| Move Selection Up | Up Arrow |
| Move Selection Down | Down Arrow |
| Exit Selected Folder | Left Arrow, Alt + Up Arrow |
Type paths or parts of a path into the search box to search the entire ARC. This works if the ARC is opened from a file or when connecting over the network. The search is "fuzzy", so small inaccuracies in spelling don' t matter like "mrio" instead of "mario". To clear the search results and return to the ARC root, delete the text in the search bar.
If the application encounters an error, click the red error icon to see details on the error. Application errors, warnings, and additional performance information are logged to the log.txt file in the executable directory. If an extract operation fails or the data.arc won't open, check the log.txt for details. Include the relevant lines from the log.txt when reporting issues if possible.
The right panel contains details on the currently selected file or folder. If a file is selected, the details panel displays information such as the file name and full path, compressed size, offset, etc. Shared files use the same data, so edits to one of the files will update all the other files shared with it. Shared files have a link icon in the file tree and a corresponding list of files shared with that file in the details view.
Folders or individual files can be extracted by right clicking the folder or file and selecting extract or by clicking extract under the Arc menu. The export directory can be customized under Settings > Preferences.
Various aspects of the program can be customized in the preferences window by selecting Settings > Preferences in the top menu. The preferences window allows toggling the dark theme, using hexedecimal or decimal for file properties, etc.
