Intermediary Mod allows to run Minecraft 1.2.5 mods on Minecraft 1.7.10 without code modification. This mod very experimental.
How do I use it?
Drop the Intermediary mod JAR into your regular Forge mods folder. Run Minecraft once, and you should see a new folder appear in your Minecraft folder called “Intermediary”. Inside there you’ll find a new “mods” folder. This is where you put your 1.2.5 mods.
How does it work?
Intermediary creates an abstraction layer for 1.2.5 mods which are attempting to access Minecraft, ModLoader, FML, and Forge. Mods believe they’re running inside of 1.2.5. Many of the Java classes involved in this abstraction layer are simply empty dummy classes so that the mods will load. Others include behavior to translate actions between the two versions as accurately as possible, despite their sometimes significant differences. The only thing of Minecraft 1.7.10’s that the 1.2.5 mods have direct access to is the OpenGL context.
- If your mod need Forge, you need download and install Minecraft Forge.
- Open minecraft.jar file at: C:\Users\(your computer name)\AppData\Roaming\.minecraft\bin or searching for “%appdata%” in your start menu. Open minecraft.jar with Winrar or Winzip.
- Open the .zip/.rar/folder of your mod and drag and drop the contents into the minecraft.jar.
- Delete the META-INF folder in the minecraft.jar. Then close minecraft.jar.
- Open Minecraft and play!
- If your mod does not work or you see a black screen: You need Delete your minecraft.jar found here “C:\Users\(your computer name)\AppData\Roaming\.minecraft\bin”. Then Open Minecraft, let it auto-update so your .jar can be restord. Attempt to re-install your mod.
