Unifideck, a Decky Loader plugin for the Steam Deck, has been released in version v0.7.3.

The tool consolidates game libraries from Steam, Epic Games, GOG, Ubisoft and Amazon into a single interface, handling cloud saves, Proton compatibility and installation along the way.

New additions include Protontricks integration for game prefix management, a language pack selector for Epic games, and a revamped “Installed” section showing game sizes, storage locations and play/uninstall options. Several bugs were also fixed, including Ubisoft prefix reinstallation loops, missing Update buttons, failed Epic installations, and issues with GOG runtimes and Amazon authentication.

Key Features Added:

• Protontricks integration for game prefix management
• Language pack selector for Epic games
• “Installed” section displaying game sizes and storage locations with play/uninstall options
• Manual cloud save location configuration with reset functionality
• Cloud saves support indicator (Supported/Not supported/Unknown status)

Major Fixes: The release addressed critical issues including Ubisoft prefix reinstallation loops, missing Update buttons across stores, Epic game installation failures, GOG runtime delivery problems, and Amazon authentication failures. Additional fixes resolved Proton version persistence issues, game stopping functionality, and automatic cleanup of leftover Proton folders.
