About the Expanded AE mod

Expanded AE currently only adds a few new features. This mod is community-driven, so suggest any ideas you might have and they might get added.

1.20.1 and 1.21.1 are both being actively worked on! I will try to keep their features somewhat equal, but no promises :)

What's included currently:

  • Expanded Pattern Provider which has 72 slots for patterns so you don't have to build workarounds if you require more pattern slots for one machine, also added is the cable part version.
  • Upgrade item, so you can upgrade existing pattern providers while keeping their patterns in them.
  • Extra blocking modes for your pattern provider.
  • Pattern modification within pattern providers.
  • Expanded Pattern Encoding Terminal + Wireless Version: Pattern multiplication/division within the terminal, shift clicking while encoding places pattern into your inventory.
  • Pattern Refiller Card for Wireless Expanded Encoding Terminal.
  • Auto Complete Card for pattern providers.
  • Co-Processing units from 2x up to 1M cores!
  • Giga Pattern Provider: 288 slots spread out over 4 pages
  • Highlight Stored Locations by Keybind of anything in your ME System
  • Rename Items in the Pattern Encoding Terminal by Ctrl+Click

Note: If you want more in-depth explanations, check the github readme or ingame guide!

How to install Expanded AE

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 1.20.1–1.21.1 on Forge or NeoForge automatically.

  3. Launch the game

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

Manually

  1. Install Forge or NeoForge

    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 expandedae-2.1.3.jar (499 KB) for your game version and loader.

  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: Expanded AE 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.
