Beta Fix

by BobDev

Beta Fix changes how a set of Beta-era mechanics behave in Java Edition, working on the client and server side of the game.

What it does

The mod targets the mechanics of Minecraft Beta, adding fixes for mining and for several blocks, including stairs, fences, workbenches, doors, trapdoors, furnaces, stone pressure plates, redstone ore, jukeboxes and note blocks. It also adds a modern pick-block option that takes a block without the old mining delay. Because it is applied at the level of the Java Agent loader, it sits outside the usual mod loader APIs.

Beta Fix runs on the client and the server, so both sides need it for the fixes to apply consistently. Files are published for six Beta and early release versions: b1.2_02, b1.3_01, b1.4_01, b1.5_01, b1.6.6 and b1.7.3, within the range b1.2_02 – b1.7.3. Snapshot builds are published alongside the release files.

The mod is not open source. It is licensed as All rights reserved, so the source code and compiled files may not be copied, redistributed, reuploaded or used as the basis of derivative works without prior written permission from the author, BobDev. Reading and studying the code for learning purposes is permitted under the same terms.

Key features

  1. Mining fixes

    Several Beta mining behaviors are corrected, so block breaking follows the intended timing.

  2. Block fixes

    Stairs, fences, workbenches, doors, trapdoors, furnaces and stone pressure plates receive corrected behavior.

  3. Redstone and note block fixes

    Redstone ore, jukeboxes and note blocks are adjusted to match the fixed mechanics.

  4. Modern pick-block

    A pick-block action takes the targeted block with no mining delay, similar to later versions of the game.

No per-version build data
Modrinth lists game versions for this project (b1.2_02 – b1.7.3), but the source data has no build per game version and loader, so the compatibility grid is not shown.

Use cases

Who it’s for: Players and server owners who play Minecraft Beta versions and want corrected mechanics.

Questions

Which loader does Beta Fix use?

Beta Fix uses the Java Agent loader and is published for the six listed Beta and early release versions.

Does the server need Beta Fix?

Can the mod code be reused?

No. The license is All rights reserved, so copying, redistributing or creating derivatives needs prior written permission from BobDev.
