• The reason for the crash is supposedly 'because Unity 3/4 does something with OpenGL contexts that is acceptable for WGL, but not for the Linux equivalent layer called GLX.' But there exists a patch for Wine that allows Unity to run in OpenGL mode, but, to add the patch, Wine has to be compiled with it included.

• This is the Wine Application Database (AppDB). Here you can get information on application compatibility with Wine. Most of the features of the Application Database require that you have a user account and are logged in. Some of the benefits of membership are: Ability to vote on your favorite applications.

Due to Updates in Firefox, Flash and Unity plugins no longer work in PlayOnLinux.

Winetricks is a helper script to download and install various redistributable runtime libraries needed to run some programs in Wine. These may include replacements for components of Wine using closed source libraries. Note: Although using winetricks may be very useful for getting some programs working in Wine, doing so may limit your ability to.

Some games can still run via Pipelight (Uses Wine Staging)

If you are still having trouble installing Adobe Flash Player, try downloading the installer directly from the following sites:

Updating Unity
When you launch a Unity game in Firefox there may be an error
'Failed to update Unity Web Player'
Click 'Error details'
Take note of the update address
http://webplayer.unity3d.com//Channels/795a449bc926/UnityPlayer3.x.x-win32.zip
Depending on the version of Unity the game was made with, the zip file will show the version to update with.
Ex: 2.x.x-win32.zip or 3.x.x-win32.zip
Note: I recommend doing this update before launching Firefox the first time because most games are running Unity 3.x.x or higher
Use your Linux browser to download this update
Save it to your desktop
Open with Archive manager
firefox39.png
Extract to this long directory:
/home/username/.PlayOnLinux/wineprefix/firefox/drive_c/users/username/AppData/LowcalLow/Unity/WebPlayer/player/Stable3.x.x
Note: username is where you put your Linux login name
Click Extract
Click Replace for existing files
The last step is fooling the updater to think we have the current Unity Upates installed.
Even though we alreay installed the updates, the player will still check a plist file and if it doesn't show the correct update, then the error starts all over again.
Navigate to the Unity folder again
/home/username/.PlayOnLinux/wineprefix/firefox/drive_c/users/username/AppData/LowcalLow/Unity/WebPlayer/
There are 3 directories:

• loader
• mono
• player

Open the player directory
Open the Stable3.x.x direcotry
Open info.plist
Right-click and open with a text editor like gedit
Also open the info.plist from the loader directory
Right-Click and open with a text editor like gedit
The XML should be different in both files.
The updated version should appear like this
<?xml version='1.0' encoding='UTF-8'?>

Copy and paste the stable version into the loader version
Do the same for the info.plist in the mono/Stable3.x.x directory too
All three info.plist files should both be identical
Save all three files and close your text editor.
Note: You may need to do this with each update you try to apply to Unity.
For now, most games run with 3.x.x

Steam Proton - Run Windows Games With Wine

Conclusion:
Most games seemed to run just fine as they do in Windows. A few ran slow like Jurassic Park and others didn't run at all. But the current Flash Player is installed and should give you more success than not playing at all.
Unity player was able to play most games with the 3.x.x update, but some older Unity games required 2.x.x and I needed to download that version and extract to play them. Applying the 2.x.x update breaks newer Unity games, so make note of which games you want to play and update accordingly.
Some Unity games still would not play because of communication with video drivers.
Most Unity games played just fine, but I did have some trouble with fullscreen settings and mouse-look. I found that unchecking the 'Automatically capture the mouse in full-screen windows' in Wine Configuration fixed this problem.
