Install Glorious Eggroll version of Proton

The built-in Proton versions so far have some issues with some titles so the customized version 'Glorious Eggroll' is a possible solution

1. Download Glorious Eggroll version of Proton from: https://github.com/GloriousEggroll/proton-ge-custom/releases
2. Extract the tarball to the directory: ~/.steam/root/compatibilitytools.d/ (note: may need to create the directories)
3. Close and restart steam

Place to put the non-steam game for ease of execution

Proton should work like WINE,but as a precaution, rather than place the executable contents anywhere, it would be better to place in ~/.steam/steam/steamapps/compatdata/pfx/drive_c/<your choice here>

To get the game to show up in Steam

The only games that automatically show up in steam are those that are from the Steam Store, however, adding non-steam games to the library is possible. Games that include a desktop entry can be added to the steam library. The launcher item only needs to be created for pslauncher, as psclient loads from pslauncher.

1. Open a menu editor like menulibre
2. Add a new launcher by clicking the + button in MenuLibre
3. Search for the Windows Executable.
4. Place the file path (minus the executable) in the "working directory" and the executable in the "command"
5. in the box that says "New Launcher" click and type a new name (this is what you will be looking for in steam)
6. Select an Icon, enter a description, select a category (optional)
7. Save the launcher entry and close menulibre
8. In steam, go to the library and click "add a game"
9. Select "add a non-steam game"
10. Click browse
11. Navigate to your home folder then ".local/share/applications"
12. The desktop entry will most likely start with menulibre-xxxx where xxxx is the name of the launcher
13. Click "open"
14. Click "add selected programs"
15. Right click the menu item choice that matches the name of the launcher and select properties
16. Can rename the item and choose an icon here. This unfortunately does not copy the data from the desktop entry. (maybe a dummy desktop entry would have been sufficient)
17. Click browse to find the executable
18. Click "compatibility"
19. Check "Force the use of a specific Steam Play compatibility tool"
20. Select Proton-6.14-GE2 (or whatever version of Glorious Eggroll that was installed in compatibilitytools.d)
21. Close the properties window
