Pack setup

How should I set up Legacy Optimized for players and a server?

Use Legacy Optimized 1.0.0 as the pack version. Install the pack as its own launcher instance. The creator’s listing does not name a separate server file, so check the release notes before setting up a dedicated server. Do not upload the ordinary client folder blindly.

Client instance Install Legacy Optimized 1.0.0

Dedicated server setup Match Legacy Optimized 1.0.0

Pack loader Fabric 0.19.3

A pack is a matched client and server setup, not one mod with an install-side label. Keep its release, loader, manifest and overrides together.

Plan the server requirements Read the Minecraft installation guide

Referenced mods 48

Client only 36

Server only 1

Not labelled 11

These numbers come from the pack file you chose. “Not labelled” means we don’t know which side it belongs on—not that it is safe everywhere. The file count is not a RAM estimate.

What are the server requirements for Legacy Optimized?

Legacy Optimized 1.0.0 on 26.1.2. The pack contents and setup notes below stay tied to that release.

48 mods in this pack file

The selected pack release is Legacy Optimized 1.0.0. That file is for Minecraft 26.1.2 with Fabric 0.19.3. It contains 48 mod projects. The creator’s listing does not name a separate server file. Check their notes before using one, and do not upload an ordinary client folder or rebuild the pack mod by mod. A file count cannot tell us the right RAM, CPU or storage; size the server for the players and world you actually run.
