I'm new to minecraft mods, I really want to play this one. I've gotten as far as installing minecraft forge but i can't get the mod into the mod file in the minecraft page. I'm using 1.6.4 and all the files i need are for 1.6.4.
The files are Galacticraft 1.6.4 and Micdoodle core 1.6.4 and are both Jar
Maybe I need to use Winrar? I don't know how to though. I DON't know what I'm doing wrong, please help
