What it does

Some mods built for MinecraftForge 47.3.10 and later rely on a constructor form that NeoForge 47.1.x does not accept by default. LexForgeFix bridges that gap by letting such mods run on NeoForge 47.1.x, and it works for the constructor that receives an FMLJavaModLoadingContext parameter. Classic parameterless constructors are handled as well, through bytecode modifications. The mod is published for NeoForge on 1.20.1 only, and both client and server need it. It is released under the MIT License and is open source, with its source code and issue tracker public.

Key features

  1. Forge 47.3.10 constructor support

    Mods that use the FMLJavaModLoadingContext constructor added in MinecraftForge 47.3.10 can load on NeoForge 47.1.x.

  2. Parameterless constructors

    Classic mod entry classes with a parameterless constructor are adjusted through bytecode modifications so they load on NeoForge.

  3. Bytecode-based fixes

    Compatibility is achieved by modifying bytecode at load time, so the mods themselves do not need changes.

What the author says

MinecraftForge 1.20.1-47.3.10 introduced a new feature: allowing the mod entry class constructor to obtain an FMLJavaModLoadingContext as a parameter, whereas NeoForge 47.1.x at the same time did not support such a mod constructor. This mod adds the classic parameterless constructor to these mods through bytecode…
