Frequently asked questions

Do I need to install this mod separately or does it come with my compatibility layer?
Mod Remapping API is a dependency that compatibility layers like Fabricated Legacy Forge install automatically—you don't need to add it yourself. If you're using one of these tools, the mod is already present in your mods folder.
What's the difference between remapping and just loading a mod normally?
Remapping translates a non-Fabric mod's code to match your game's current mapping system at startup, so mods designed for other loaders can run on Fabric. Without remapping, these mods would crash because their code references outdated or incompatible names.
Can I use this to run old Forge mods on modern Fabric?
Mod Remapping API provides the foundation for this, but you need a compatibility layer like Fabricated Legacy Forge on top of it—the API alone doesn't bridge the loader gap. The compatibility layer uses the remapping hooks to make old mods work.
Why is my mod still crashing even though remapping is enabled?
Remapping handles code translation, but some mods have deeper incompatibilities (missing dependencies, incompatible APIs, or version mismatches) that remapping can't fix. Check the crash log for the actual error and verify the mod is compatible with your Fabric setup.
