如何安装 BackSlotAddon

With Millida Launcher

  1. Install Millida Launcher

    The launcher is free: download it at millida.net/launcher and sign in with any nickname.

  2. Click “Install” on this page

    The launcher opens and installs the mod for Minecraft 1.21.1 on Fabric automatically.

  3. Launch the game

    A profile with it appears in the launcher: click “Play”.

Manually

  1. Install Fabric

    The loader must match the game version of the mod file, for example Minecraft 1.21.1. After installing it, a separate profile appears in your launcher.

  2. Download the file for your version

    In the version list above, pick the file backslotaddon-1.1.2.jar (29 KB) for your game version.

  3. Put it in the mods folder

    The folder is inside .minecraft (Windows: %appdata%\.minecraft\mods). If it does not exist, create it.

  4. Launch the loader profile

    Open “Mods” in the main menu: BackSlotAddon should be in the list.

Minecraft 1.21.1 runs on Java 21: with a different Java version the game may close right after launch.

常见问题

Which Minecraft versions does BackSlotAddon work on?

Only Minecraft 1.21.1: there are no files for other versions.

Is BackSlotAddon for Forge or Fabric?

Only for Fabric: 1.21.1. There are no files for Forge or NeoForge: a mod for another loader will not start.

Does BackSlotAddon need other mods?

The author lists no required dependencies: the Fabric loader is enough.

Which Java does BackSlotAddon need?

Minecraft 1.21.1 runs on Java 21. If the game closes right after launch, the usual cause is the wrong Java version in the profile settings.

Where can I download BackSlotAddon safely?

On this page: the file backslotaddon-1.1.2.jar (29 KB) is stored on Millida’s server, with no link shorteners. SHA-1 checksum: ebdbbaa4255332a1dc33414883858a565f0e939c.
