Standard Mods (JAR Mods)

Unless labeled otherwise, all mods you can find on Chunk Base are JAR mods. To install them, you have to overwrite the contents of your Minecraft’s jar file. Here are some step-by-step instructions using WinRAR (feel free to use any other capable archiving tool with a GUI).

Third-party Launchers

You can simplify the installation process by using a custom launcher like Magic Launcher. Depending on the launcher, you usually have to add the downloaded zip file as a (jar) mod.

Minecraft 1.6.1 and up (new launcher)

Download the mod

If you haven’t done so already, start the official launcher to download the version of Minecraft you want to use (e.g., 1.6.1)

Go to the “versions” folder inside your minecraft installation (by default %appdata%/.minecraft/versions on Windows)

Create a copy of the folder whose name corresponds to the Minecraft version you want to use and name it however you want (e.g., 1.6.1_modded)

Inside that folder, rename the existing .jar and .json files according to the folder name you just chose

Open up the .json file in a text editor and replace the contents of the second pair of quotes with the folder name. For example, change “id”: “1.6.1” to “id”: “1.6.1_modded”

In newer versions of the launcher (~2016), you also have to prevent the launcher from redownloading the original jar file by changing “downloads” to (e.g.) “_downloads”. Do this only for the lowest occurence of “downloads”, which should be followed by URLs and checksums of the client and server

Do steps 2-6 listed below (for Minecraft 1.5.2 and below), using the jar file you just renamed instead of minecraft.jar

Start the official Minecraft launcher, click on “Edit Profile”, and, under “Use version”, select your newly created version (in this case, 1.6.1_modded)

Save the profile, click “Play” and enjoy ;)

Minecraft 1.5.2 and below (old launcher)

Download the mod.

Open both the downloaded mod and minecraft.jar (in your minecraft/bin folder, which is by default %appdata%/.minecraft/bin on Windows) with WinRAR.

Bring the minecraft.jar window to front, select the META-INF folder and press the delete button at the top. You may have already done this step before for another mod.

Bring the window of the mod archive to front and select all files and folders inside the archive.

Drag and drop the selection into the minecraft.jar archive’s window, or: press Ctrl + C , bring the minecraft.jar window to front and then press Ctrl + V .

Close both WinRAR windows

Start Minecraft and enjoy ;)

Compatibility Versions

Mods labeled as compatibility versions make it possible to use the mod you downloaded here together with another mod, which would cause conflicts otherwise. They’re essentially JAR mods as well, so follow the instructions for JAR mods in order to install them. Also, make sure to install the mod from here last. When using third-party launchers, you should be able to define the order in which the mods are loaded.

Forge Mods

You can install forge mods by simply copying the .zip or .jar file you downloaded to the “mods” folder of your minecraft installation. However, you need to have Minecraft Forge installed. For more information, please go to minecraftforge.net.
