Still, the games are the ultimate prize, and when they are compatible, theyre playable without issue.
To make it work, though, youll first need toinstall Proton GE(Glorious Eggroll).
Be sure to have Proton GE already installed before you begin the following steps.

I also highly recommend using a USB-C hub or Bluetooth to connect amouseto your Steam Deck.
It’s up to you, though.
Ourbest Steam Deck accessoriesguide has some USB-C hub/docking station recommendations that will make hooking up peripherals much easier.
Step 1:Hold down the Steam Deck’s power button and select “Switch to Desktop”.
Step 2:Open up your preferred net web client and head to the Battle.net download page.
grab the Windows installer, and it should download in short order but dont launch the .exe just yet.
Instead, we need to add it to Steam.
Then, select “Add a Non-Steam Game to My Library” from the drop-down list.
Step 5:Look for the executable, named “Battle.net-Setup.exe”, in your Steam Library.
Again, dont bother launching it yet.
Once selected, it’s possible for you to exit the Manage window.
Step 7:Now you could hit Play to launch the installer through Steam.
Run through it normally, just as if you were installing Battle.net on a Windows PC.
After but mere moments, Battle.net will be ready to access.
Dont do so just yet, as we still need to add Battle.net itself to the Steam Library.
Close Battle.net for now.
From there, navigate tohome/deck/.local/share/Steam/steamapps/compatdata/.
Open that up, then navigate topfx/drive_c/Program Files (x86)/Battle.net.
Step 9:Nearly finished, dont worry.
Just like with the installer, find the Battle.net launcher in your Library and open up its Manage menu.
Head to Compatibility, check the box, and select Proton GE again.
Step 10:Aaaaaaaand donezo.
Step 2:bring up the Discover tool its the little shopping bag-shaped icon in the Desktop Mode taskbar.
Step 4:Launch Lutris and hit the “+” icon in the top-left corner.
Then, select “Search the Lutris website for installers”.
Click “Install”.
Once youve made your selections, tap the blue “Continue” button.
Click “Install” on this so that Lutris can continue.
From there, you might finally launch Battle.net, jump in, and start downloading games.
To launch it in the future, just find Battle.net in Lutris Games tab.
