Unifideck, a Decky Loader plugin for the Steam Deck, has been released in version v0.7.5.

The tool consolidates game libraries from Steam, Epic Games, GOG, Ubisoft, Amazon, Xbox Cloud Gaming and Battle.net into a single interface, handling cloud saves, Proton compatibility and installation.

The headline addition is GameVault integration for installing and running DRM-free games, either from your own GameVault server or from a local folder. Unifideck can now also reuse GE-Proton versions installed outside the plugin (for example via ProtonPlus), and a cart icon opens the landing page of any signed-in store directly from the plugin UI. The release also ships 18 bug fixes.

New Features

• Added GameVault, so you can browse and install from your own GameVault server or from local folder of game files
• Added support for GE-Proton installed outside Unifideck, such as through ProtonPlus. Unifideck can now use existing protons instead of downloading them again
• Added a way to open logged in stores from the plugin UI via the Cart icon
• Improved the plugin updater. UI is more compact now and update options open in a new popup
• Added a visible badge when Unifideck has stopped retrying a game that keeps failing to launch, with a button to reset it and try again
• Added better support for Steam Machine and its own tab and compatibility classifications
