Authentic Beta
As close as possible to (vanilla!) Beta 1.7.3 in modern-ish versions.
Quick answer
Which Authentic Beta release should I use?
Authentic Beta CLIENT 1.2_02 is a complete pack release for 1.20.1 with Fabric 0.19.2. Install it as its own launcher instance. If the creator publishes a separate server file, make sure it names this exact pack release. 72 mods in this pack file.
Pack setup
How should I set up Authentic Beta for players and a server?
Use Authentic Beta CLIENT 1.2_02 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.
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.
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 Authentic Beta?
Authentic Beta CLIENT 1.2_02. Change the pack release and its contents or setup may change too.
The selected pack release is Authentic Beta CLIENT 1.2_02. That file is for Minecraft 1.20.1 with Fabric 0.19.2. It contains 72 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.

Q&A
Q: Server support?
A: Yes! Read the How to Install section!
Q: Where do I report issues or make suggestions?
A: Join the Discord server, or go to the Codeberg page!
Q: Is this just nostalgia bait?
A: No, even if you never played Beta you can still enjoy Authentic Beta!
Q: Forge?
A: No :3
Q: Can I use this as a base for my own modpack?
A: Of course! Just credit me and let me know about it, please :3 (and follow the terms of the license, of course)
Q: What's the difference between the 1.20.1 and 1.21.1 versions?
A: The 1.20.1 version has more accurate mechanics compared to the 1.21.1 version, as KubeJS has not been ported to Fabric 1.21.1.
Q: Is this modpack completely accurate to Beta 1.7.3?
A: No, and it never really can be. Despite this, I am trying to make it as accurate as I possibly can within my abilities. There are some things I've left in intentionally, such as sign editing and inventory QoL, because I feel that it would not be beneficial to remove them for the sake of complete accuracy (although this is always subject to change, mostly depending on how easy it is to change :P).
Q: Does this project use AI?
A: Absolutely not.
