Thanks a lot Chaotictissue, I downloaded all of the DLC contents. Now, I put all of the .pkg files in the root folder of my USB (FAT32, I used this one to intall all other pkg, ig. multiman), I couldn't install it before but I changed the .PKG to .pkg, then I successfully installed all of them. But the problem is none of the DLC shows up in my Fast Traveling Post.....
Maybe US and EU versions are still different, they were installed in a different folder?
