    Copy the zip from the latest release onto the SD so the plugin is in the following folder:



    Place your files in the following folder:

    For example, if you want to replace the file

    you place it in

    Note: In some Arc tooling, regional files will show up with a +us_en (or another region code) at the end of the filename. Do not include this.


    As of version 0.1.4, ARCropolis uses a configuration file that can be found here:

    If you do not have one, it will be created the next time you run Smash Ultimate, with a default configuration (The same one ARCropolis used prior to the use of a configuration file).

    This configuration file is made in an effort to support workspaces generated by Quasar by Mowjoh, a mod downloader and manager for Smash Ultimate (and more!) with support for one-click download for GameBanana mods.

    Even so, you can manually edit the configuration file using any text editor of your choice to change the directory where files and streams are read from.

    Error messages have been added for most cases, so if you manage to butcher your configuration somehow, don't open an issue for it. Delete your configuration file and generate a new one.

    Ultimate Mod Manager Backwards Compatibility

    The plugin also supports backwards compatibility with UMM paths to allow for mods to continue to work. You can simply rename your UltimateModManager folder to ultimate and all mods will work. If you no longer need UMM, it is recommended you delete your data.arc file from romfs.
