Worked on the srid/nixpkgs repository to upgrade the Cemu emulator from version 2.0-92 to 2.2, focusing on updating build configurations and patch sets to accommodate new dependencies and improve compatibility with recent libraries. Utilized Nix for package management and configuration management, making targeted changes to CMakeLists.txt and related build scripts to ensure reproducibility and performance enhancements. Addressed a metadata issue by correcting a maintainer’s display name, ensuring accurate contact information for ongoing maintenance. The work demonstrated attention to build system configuration and repository health, resulting in clearer ownership and more reliable package builds within the Nix ecosystem.
