Corrupt My Game

A class corruptor patches parts of the game's code, often removing pieces that the game needs. In most runs the game will not even start, and when it does, some odd behavior tends to follow. The JVM corruptor takes a different route: it swaps important values through reflection, so true becomes false and false becomes true, until the game gives up. A Detonate JVM button in the settings starts the JVM corruptor and destroys the runtime in real time.

Class corruption is deterministic when it targets specific Minecraft versions under the same loader, so a configuration can be saved and shared with friends for the same corruption. JVM corruption scrambles the values that Java uses, which means the same corruption cannot be reproduced. The engine settings can be imported and exported, and they persist between restarts, so a setup can be kept for later. The mod is meant to be used alongside a normal Minecraft save, since corruption can lead to save corruption and data loss.

The mod targets Minecraft 1.6.4 – 1.21.1 on Forge, and from 1.13 on NeoForge. Files for 1.21.1 are the latest on both loaders, and the license is the MIT License, so the code is open source and public links include the source code.
