Installation and Upgrades

Installation and upgrades

Install the normal mod JAR, not the sources or Javadoc JAR, on the client and server as applicable.

Install	Version for this handbook
Minecraft and NeoForge	Minecraft 1.21.1; NeoForge 21.1.265 is the build target. Mod metadata accepts 21.1.247 and later in the 21.1 series.
Power Advantage Revived	3.1.2 for 1.21.1 NeoForge
MMDLib	Matching NeoForge 2.0.x build
MMD OreSpawn	4.1.0 or later, for 1.21.1 NeoForge

Base Metals is not required to load the mod. Some recipes, including steel components, need a materials mod or data pack that supplies their ingredient tags. The standard pipe has vanilla iron and copper recipes.

Start a fresh world. This is not a supported migration from Power Advantage 2.x, the original expansions, or basePower. Old registry names are not a promise that old machine state or inventories can load. Keep old worlds and their mod sets separately backed up.

For a load error, check the game version, loader, and dependency JARs in the log before investigating a machine. Steam Advantage 3 and Electric Advantage 3 are optional expansions, not substitutes for the core mod.
