Matter Overdrive (Unofficial Port)

Matter Overdrive 1.0.2 for NeoForge and Fabric, Minecraft 1.21.1 – 1.21.10 (Java 21) and 26.1.2, 26.2, 26.3 (Java 25). Unofficial port of Matter Overdrive by Simeon Radivoev (GPL-3.0).

What's new

• Minecraft 26.1.2, 26.2 and 26.3, on both NeoForge and Fabric, with the same content as 1.21.x: all machines, matter, androids, weapons, anomalies, the galaxy, quests and world content.
• Fabric for every version (1.21.1 – 26.3). Requires Fabric API. Energy is FE through Team Reborn Energy (included in the jar, 1 E = 1 FE); items and fluids use the Fabric Transfer API, so cables and pipes of other Fabric tech mods connect to the machines.
• NeoForge and Fabric are built from the same code, so both loaders behave the same.
• Tritanium crates visible again on 1.21.1 and 1.21.3 (they were invisible in 1.0.1 there, but still opened and kept their items).
• 26.x only: the crates' colour overlay is cut out as its texture intends (1.21.x drew the overlay's transparent pixels in the dye colour), and the android shield, star map and other holograms are drawn correctly with the new renderer.

Tested

• All 101 in-game tests (GameTests) pass on NeoForge and Fabric for 1.21.10, 26.1.2, 26.2 and 26.3 (95–101 on the older 1.21.x versions).
• A scripted client scene of 142 screenshots (every machine, GUI, mob, structure, weapon and the star map) on both loaders, and the Fabric release jar in a production client.
• Performance against vanilla: a base of 576 working Matter Overdrive machines and pipes costs about what 576 burning vanilla furnaces cost, in frame rate and in server tick time.

Install

Put the jar for your loader and Minecraft version into mods/ on the server and on every client. Java 21 for 1.21.x, Java 25 for 26.x. Fabric also needs Fabric API. Worlds from 1.0.1 load as they are.
