Setup: Prism Launcher

Prism Launcher is the recommended way to play DEVGRU MC. It runs the packwiz installer before every launch, so your mods always match the server.

What you need

Section titled “What you need”

1. Install Prism and sign in

Section titled “1. Install Prism and sign in”
  1. Install Prism Launcher for your operating system.
  2. On first launch, step through the setup wizard: pick a language, let Prism detect Java, then add your account under Add Microsoft account and sign in. Your username should appear in the top-right.

2. Create the instance

Section titled “2. Create the instance”
  1. Click Add Instance.
  2. Name it DEVGRU MC.
  3. Select Minecraft version 1.20.1.
  4. On the right, choose Forge and pick version 47.4.10. This must match the server exactly. packwiz does not install the loader for you, so you set it here.
  5. Click OK and let the loader download.

3. Add the packwiz installer

Section titled “3. Add the packwiz installer”
  1. Download packwiz-installer-bootstrap.jar from https://github.com/packwiz/packwiz-installer-bootstrap/releases
  2. Put it in the instance’s Minecraft folder. In Prism, right-click the instance, choose Folder, then open the minecraft folder and drop the jar there.

4. Set the pre-launch command

Section titled “4. Set the pre-launch command”

  1. Right-click the instance and choose Edit Instance.

  2. Go to Settings, then Custom commands.

  3. Check the Custom commands box.

  4. In the Pre-launch command field, paste this exactly:

    "$INST_JAVA" -jar packwiz-installer-bootstrap.jar https://stickman112.github.io/devgru-mc-pack/pack.toml

  5. Close the edit window. Settings save automatically.

5. Launch

Section titled “5. Launch”

The modpack only downloads if the pre-launch command from step 4 is set; launching without it boots Forge with no mods.

  1. Click Launch.
  2. A small packwiz installer window appears first and downloads the modpack. The first run takes longer because it fetches every mod; later launches only download what changed.
  3. Minecraft then boots to the Forge title screen.
