    • i know how to do it
      its simple open the guiAPI with winrar and pout the content files into the .minecraft .
      REMEMBER delete META-INF
      then put mo creatures mod and custom mob spawner into your mods folder
      AND i ope it works with you because it works with me 🙂

  • Neither of the ways work.
    There is no “coremods” folder at all, and making one does not work. Forge is correctly installed. Extraction makes no difference.
    Putting either the extracted files or zip in the .minecraft does not work, or even just the “mods” folder.
    How the hell do you install this on 1.6.2?!!

  • I have the same issues as the other comment. I have forge and mod loader installed ( up to date) but no core mods folder. Also when I put the files directly into the minecraft.jar that doesn’t work either. I just get unexpected crash reports. So frustrating I don’t know what else to do. :/

  • Well,first of all,FORGET THE COREMODS FOLDER! The only folder you need for mods now is the MODS folder. Put everything in the mods folder and you should be good. Second of all, the 1.6.2 download link doesn’t work, help please I want Mo’ Creatures but the GUI API link won’t work!
