Auto-updating Modpack

Set it up once. After that it updates itself every launch — you never re-download anything.

This uses Prism Launcher (free) plus a tiny helper that syncs the pack from the server each time you press Play. New mods, updates, removals — all automatic.

Prefer not to set this up? You can still grab the pack as a one-off manual download (won't auto-update).

One-time setup

  1. Install Prism Launcher and sign in with your Microsoft account.
  2. Click Add Instance → choose Minecraft 26.1.2 → on the right pick Fabric → Create.
  3. Right-click the new instance → Folder. This opens its .minecraft folder. Put this file inside it:
    https://jackiscool.com/pack/packwiz-installer-bootstrap.jar
  4. Right-click the instance → Edit → Settings tab → tick Custom commands. In Pre-launch command paste:
    "$INST_JAVA" -jar "$INST_MC_DIR/packwiz-installer-bootstrap.jar" https://jackiscool.com/pack/pack.toml
  5. Press Play. It downloads every mod automatically, then launches. Join with server IP jackiscool.com.

That's it

From now on, just press Play. Before the game opens it quietly checks the server and pulls any new or updated mods. You're always in sync — nothing to click, nothing to re-download.

Java & Bedrock crossplay still works in-game. Questions? Ask in chat or on the server.
