Unfortunately not.
So is the DLC license-based, can I just drop some files into the native Steam directory or is it its own client despository included with the native exe hosted here? The game looks like hot ass but I'm trepidatiously curious.
You would have to unpack the files in whatever tool the creator used when creating it, and put the new content into the cracked game. I tried just copy-pasting some of the new files over and it ended with the girl scrambled, as if every gamemode and option was active at once.
I've reached out to the Original poster through the thread a few weeks ago, and just today, about getting the updated version re-cracked. But the guy who originally cracked it disappeared off the site 2 years ago, so it's annoying. Might be better off just submitting a re-crack request, but then someone would have to buy the game. I enjoy it, but I don't enjoy it enough to have my friends and family see it in my library.
Edit: The OP got around to responding, said he's not the one who cracked it. We might need a new crack request with someone who owns the game and dlc. He didn't grok the idea that I presumed he was the owner who provided the original un-cracked copy with dlc.
Edit: OP does not have the game, the cracked game was uploaded by a third-party who did it for the challenge and is no longer on the site.
