this worked once for me, but I had to do it again because I was using a 32 bit engine, not 64, and I'm stuck on this one frustrating part. whenever I enter this information into the config, it just resets whenever I try to open steam again. It goes back to a very simple format, only with this :
Note that at the moment it won't work on macos, and on Linux, you'll have to reinstall Steam or simply remove config.vdf file after installing current wine-git. First version to contain the fix will be 3.12, which is not released yet.
