I’m looking into finding a way to get access to the DLC packs for Rocksmith 2014 which have been delisted due to their licenses expiring.
I’ve been able to find some repacks that come with all of them bundled in as one, but I own a legitimate copy of the game itself. Is there any way to trick Steam into allowing me to use those files without a license attached to my account?
Are you on windows or linux, if you managed to fond the dlc files, you can most likely(not 100% sure it works with delisted) use creamAPI to make steam think you on them. On windows I’ve used CreamInstaller, which is a handy GUI that does it for you. I seem to recall I did it on my father computer running ubuntu, but don’t recall exactly how.
creaminstaller works under linux and can find steam games inside your home folder (not sure about elsewhere) if you run it as a third party exe in steam with proton
