Proton 6.3-7 + SCP Patch

---

Right now, using this appears to cause a Hardware ID ban. As I wrote previously, use this at your own risk.

Patches Proton 6.3-7 to fix the game "SCP: Secret Laboratory." See ValveSoftware#4229 (comment).

Install by extracting release.tar into your Steam compatibilitytools.d folder (~/.steam/root/compatibilitytools.d, make one if it doesn't exist). Make sure the folder is one level deep, so the file structure looks like this:

compatibilitytools.d
└── scp-proton-6.3-7
    ├── compatibilitytool.vdf
    ├── filelock.py
    ├── LICENSE
    ├── LICENSE.OFL
    ├── proton
    ├── proton_3.7_tracked_files
    ├── proton_dist.tar.gz
    ├── toolmanifest.vdf
    ├── user_settings.sample.py
    └── version

After that, open the compatibility tab in SCP:SL's Steam game properties. Check "Force the use of a specific Steam Play compatibility tool," and then select "Proton 6.3-7 + SCP Patch" in the dropdown. Close the properties window and hit play. It may take one or two launches to work properly.

As Linux isn't officially supported, use this at your own risk. Anticheats are notoriously finicky when it comes to using Wine, and your account may get falsely flagged as cheating. While I haven't had any issues so far, there are no guarantees that this will continue working in the future.
