From the unzipped LWJGL folder, navigate to the 'native' folder. jar file was copied to (from /lwjgl-(version number)/jar/*.jar to /mcp62/jars/bin/*.jar). From the unzipped LWJGL folder, navigate to the 'jar' folder, and copy 'lwjgl.jar', 'lwjgl_util.jar', and 'jinput.jar' into the same MCP 'bin' folder that the Minecraft client.

LWJGL files: Unzip the downloaded LWJGL.

jar file to this directory, and rename it to 'minecraft.jar' (/mcp62/jars/bin/minecraft.jar). Make a new folder in the 'jars' folder, and name it 'bin'. jar file to this directory, and rename it to 'minecraft_server.jar' (/mcp62/jars/minecraft_server.jar). jars: Inside of the mcp62 folder, navigate to the 'jars' folder. Using the program dos2unix is an easy way to do this.

Newline fix: If the OS you're using is not Windows, you may need to convert the line endings in the file /mcp62/conf/astyle.cfg to Unix style line endings (this was an issue for me when using MacOS).

Removing it prevents MCP from trying to update. This link is no longer functional, and MCP will fail upon trying to communicate with it.

Broken link fix: Inside of the mcp62 folder, navigate to the 'conf' folder, and modify the 'mcp.cfg' file (/mcp62/conf/mcp.cfg) to remove the line containing 'UpdateUrl' (line 124 in mcp62).

Fernflower fix: Copy the 'fernflower.jar' file from mcp70a to the same location under mcp62 (/mcp62/runtime/bin/fernflower.jar).

Forge: Unzip the Forge source distribution you downloaded, and move the unzipped forge folder to inside of the unzipped mcp62 folder (/mcp62/forge).

MCP: Unzip mcp62, and move the unzipped folder to your project directory.

It might be a good idea to re-install a supported JDK after installing the older one, to make sure that environmental variables or various platform binaries are up to date. Note: these versions of Java are likely not secure, use them at your own risk.

If you're on MacOS, you'll need to install Apple's Legacy JDK 6.

If you're on Windows or Linux, Oracle hosts JDK 6 downloads on this page.

I can only speak for MacOS based JDKs, but when using any JDK newer than Apple's Legacy Java 6 JDK, Forge's patches fail to apply to the decompiled source code.

JDKs: ( Possibly optional, but recommended) As Minecraft 1.2.5 and mcp62 were made using an older JDK, I'd recommend using JDK 6 when decompiling & modding with them (or the closest possible substitute).

An easy way to get both files is through the download links on the Minecraft wiki page for 1.2.5. jars: Get a copy of the 1.2.5 client Minecraft. Alternatively, download the latest release (LWJGL 2.9.3) from here.

LWJGL: If you want to use an authentically janky old version of LWJGL, download LWJGL 2.4.2, which can be found here (download the file named 'lwjgl-2.4.2.zip').

Copy this file to where you're storing all of these downloaded files. You can find the fernflower.jar file at /mcp70a/runtime/bin/fernflower.jar. Download mcp70a from the same Minecraft wiki page, and unzip the files. Luckily, this version of Fernflower can be found in mcp70a. This version of Fernflower is important, as using newer versions of Fernflower will break Forge's patches, which were intended to fix some of Fernflowers decompilation bugs at the time.

Fernflower: You'll also need to obtain a specific version of Fernflower, as the automatic download link mcp62 used is now non-functional.

The Minecraft wiki has a list of MCP versions with download links here.

Minecraft 1.2.5 free download windows mod#

MCP: Download the Mod Coder Pack for 1.2.5 (mcp62).

These can be found on the official Forge website.

Forge: Download the Forge 1.2.5 source distribution you'd like to use (it's recommended to use the latest released version).

Make sure to always have a backup copy of all of these downloaded files! I'd recommend putting them into a seperate folder from your MCP / Forge project directory. The links have changed and Minecraft 1.2.5 isn't able to download them anymore. TODO: Add a section on installing the resources (sounds) folder to the MCP environment.
