Mod downloader, manager, updater for Super Smash Bros Ultimate
Getting Started with Quasar should be pretty straight-forward. The only step I would recommend doing before using it is making a backup of your mod folders on your Switch's SD. This will allow you to revert easily to your mods before you used Quasar, if that's your wish.
Being on Windows, having Admin rights for the installation. You also need the .net 5.0 runtime here
On your Switch, you will need both ARCropolis and Skyline
Install the provided .msi in the releases section
Quasar is an app that relies on the website https://gamebanana.com
To download mods for use, please head to the website and look for Super Smash Bros. Ultimate mods.
When you browse the page, it will display a Quasar Download link.
Click it and the mod will be downloaded by Quasar and ready for use.
