Installing Mods

Copper Launcher supports both Forge and Fabric mod loaders out of the box.

Step 1 — Install a Mod Loader

Forge

  1. From the launcher home screen, tap the version selector.
  2. Tap Forge at the top of the version list.
  3. Select the Minecraft version + Forge version you want.
  4. Tap Install and wait for it to complete.

Fabric

  1. Tap the version selector.
  2. Tap Fabric.
  3. Select your desired Minecraft + Fabric Loader version.
  4. Tap Install.

For Fabric, also install Fabric API — most mods require it.

Step 2 — Add Mods

Once a mod loader is installed, mods go in the mods folder inside your Minecraft directory.

From the launcher, tap Folder icon → Game Directory, then open the mods folder. Download mods from Modrinth or CurseForge, then place the .jar file in the mods folder.

Only download mods from trusted sites. Unofficial mods may contain malware.

Troubleshooting Mods

Game crashes after adding a mod? Make sure the mod is compatible with your Minecraft version and all dependencies are installed. Remove recently added mods one at a time to find the culprit.

Mods not showing in-game? Confirm the .jar is in the correct mods folder and you launched the correct Forge/Fabric profile.
