To get items, you download an item pack, save it to desktop and open it with winzip/WinRAR/whateveryouuse. Then, you get the .cfg file, which should look like either a piece of paper or a notepad, and export it to C: > Feralheart. WHen it asks to replace, click YES.
Next, there should be a folder in the winzip/WinRAR/yougetmypoint that says items or something like that. Click it, and select all of its contents. Export them all to C: >>> feralheart >> media > items and REPLACE.
If you followed all this exactly, voila, you should have new items!
