It looks more complicated than it is.

Make an account.

If you are an English speaker. Go to the English forums.

The main forum and steam content sharing are basically all you have to focus on.

Steam content sharing is games without any crack. Just clean steam files.

The main forum contains the discussions about the actual cracks. This is where the actual forum part comes in.

Use the search bar to find the game you want. (Eg. Fallout 4)

Some games have 10 pages, some have 30 and some have 100+.

You can search within a topic (Eg. Fallout 4) with the search bar. Like searching for pre-made working Linux versions. Or you can search manually by reading, go from either the first or last page and go from there.

Sometimes the crack will be seperate from the game and sometimes it will be included, it depends on who you download from.

I probably made it more confusing but I hope I helped a little.
