EAM ExpMod

The mod is described by its author as a test build of a cross-version, cross-platform loader. It is delivered as a Java Agent, which the game attaches through a JVM flag rather than through a mod loader such as Fabric, Forge or NeoForge. The author states that testing needs Java 25 and that the agent is started by passing the JVM flag shown in the author text.

The agent reads its parameters from the -mod argument. Entering -help under that argument lets the game start only to print help, and local help flags are listed in the author text. A string entered under the version argument selects the file site or build to use. The author plans to add more blocks and items, ways to expose internal mods, and extra features such as a Tool Gun x86 emulator.

Files are published for 1.21.1 only, on the alpha channel, with the latest Java Agent build dated 2025-11-28. The mod is open source under the GNU Affero General Public License v3.0 only. Its source code and issue tracker are public, and the author asks that problems running it be reported on GitHub. Because it runs on the client alone, only the player's game needs it.
