Setup (Getting Started)

What do I need to run ARCropolis?

• A Nintendo Switch running the latest Atmosphère (any other Custom Firmware is unsupported)
• An up-to-date Super Smash Bros. Ultimate (cartridge or digital)

How do I install it?

Download the latest stable release of ARCropolis by clicking on release.zip under the changelog. Extract the release.zip and put its content (the atmosphere directory) at the root of your SD card.

If you did everything properly, a file called libarcropolis.nro should be located in the following directory:

    sd:/atmosphere/contents/01006A800016E000/romfs/skyline/plugins/

Then, download the latest Skyline build by clicking on skyline.zip Extract it in the following directory: sd:/atmosphere/contents/01006A800016E000/

If you did everything properly, a file called subsdk9 should be located in the following directory:

    sd:/atmosphere/contents/01006A800016E000/exefs/

How can I confirm if ARCropolis is in use?

Check the version indicated on the title screen of the game. If everything went well, ARCropolis' version should be displayed.

How can I update it?

There are currently two methods of updating ARCropolis.

• Manually updating it by repeating the steps in How do I install it? and overwriting the files on your SD
• Use the auto-updater feature built into ARCropolis (requires being connected to the internet)

What if I am an Ultimate Mod Manager user?

You can keep your UMM mods simply by renaming the sd:/umm/ directory on your SD to sd:/ultimate/.
Make sure to rename or delete your data.arc file in sd:/atmosphere/contents/01006A800016E000/romfs/ as it will cause issues, especially after a game update.
