Insanity Wrapper
Insanity Wrapper lets Fabric and Quilt mods load on NeoForge, bridging the two frameworks in one NeoForge environment on Minecraft 1.21.11.
What it does
The compatibility layer converts Fabric and Quilt mods so they run on NeoForge. It relies on NeoForge's native Mixin system, which handles the injected code, and it converts Access Transformers at runtime with access widener conversion. Fabric mods can interact with NeoForge mods through the event bus, and packets are translated between the two sides without manual conversion.
Installation means dropping the mod into the mods folder next to compatible Fabric or Quilt mods. No complicated setup or extra configuration is described by the author. The project is built on three systems that work together, and the author plans further updates, including a future entry for C2ME Concurrent Chunk Management Engine. Files are published for NeoForge only, for Minecraft 1.21.11, and the client is required while the server is optional. The mod is released under a custom license and is not open source, though its source code and issue tracker are public.
