Windows has a secret database that makes your old games

Microsoft's Windows operating system has developed intricate compatibility mechanisms over decades to ensure that older games can run on modern machines. It maintains compatibility databases that recognize software with known issues and applies specific fixes, known as shims, which adjust the OS's responses to meet the game's expectations without modifying the game's executable. Users can also manually apply fixes through Compatibility settings, allowing them to emulate earlier operating system behaviors and address specific issues. The compatibility shims can modify interactions with APIs, file handling, system privileges, and display scaling. Microsoft provides AppHelp warnings for applications with known compatibility issues and maintains a comprehensive compatibility database located at C:WindowsAppPatch. Users can access this database and explore compatibility settings using the Windows ADK and the Compatibility Administrator tool.

Project Xodus Brings Native Xbox PC and Game Pass Games to Linux

Project Xodus is an open-source initiative focused on reverse-engineering Xbox PC and Game Pass titles to enable their use on Linux and Mac systems. The project has made significant progress in Microsoft authentication and package decryption, allowing Linux users to download and process Xbox subscription games locally. The team has successfully reverse-engineered Microsoft’s identity services and license verification systems, unlocking encrypted MSIXVC game files and enabling the verification of game licenses and decryption of installation packages on non-Windows operating systems. Xodus serves as a translation bridge for Microsoft’s proprietary ecosystem services, providing custom proxy libraries for games to function as if they are running in a native Windows environment. It specifically targets modern games built on Microsoft’s GDK framework, excluding older titles using the Universal Windows Platform and those dependent on kernel-level anti-cheat mechanisms. The project aims to improve access to Xbox Game Pass on devices like the Steam Deck by facilitating direct local hardware execution, reducing reliance on cloud streaming and enhancing portable gaming experiences. Community feedback has been positive, with developers actively sharing updates and engaging with inquiries.
