Mod Manager (Features)

The Mod Manager will list all folders in the ultimate/mods directory.

Accessing the Mod Manager

To access the Mod Manager while in-game, navigate to the Main Menu of Smash Ultimate, then open up the Nintendo eShop in the lower right corner of the screen. Then select Mod Manager (ARCadia-RS).

The manager looks like this (albeit with a different mod on the page). It will display all your mods and you can toggle them as you wish. Leaving the menu after toggling a mod will prompt the game to ask you if you want to restart. Hit yes if you wish to have your mods loaded, hit no if you wish the mods to be loaded the next time you start up your game.

If booting up Smash from the Switch main menu, the mod manager can be booted during the Switch's loading screen by holding down the Plus button after the Joycons snaps once in the bottom right hand corner (example animation below, specifically a second or so after the whole animation ends). If done successfully, then the menu will display with the same options as if accessing in-game.

The main benefit of using the manager in this format is that after enacting changes the game will load as normal with the new changes, eliminating the necessity to reload the game.

Displaying Mods with Image Previews and Descriptions

Folder Config

Each folder can contain two of the following files:

• info.toml (A toml file containing information related to the mod)
• preview.webp (A webp file that can either be animated or static for previewing a mod in the thumbnail)

Note that these files are optional and do not affect mods, though if the info.toml is malformed and the user will be notified.

info.toml fields

• display_name The name that's displayed on the mod manager instead of the folder name : Default is the folder name
• version The version of the mod that will be shown below the thumbnail (doesn't have to match up with Smash Ultimate or ARCropolis) : Default is ???
• description The description of the mod that will be shown below the version : Default is nothing
• category The category the mod will belong to. A mod can only have one category : Default is Misc. Here's all the current categories:
  • Fighter
  • Stage
  • Effects
  • UI
  • Param
  • Audio

info.toml template

Here is a template of the info.toml, provided by Segtendo of the Smash Ultimate Modding Server:

display_name = "Mod name goes here"
authors = "author(s) go here"
version = "1.0"
description = """
Description for mod goes here
"""
category = "Fighter, Stage, Effects, UI, Param, Audio, Misc"

Don't forget to remove the other categories when editing the info.toml for your mod.

Still confused about info.toml?
