Worked on enhancing the gaming experience in the Gaming-Linux-FR/GLF-OS repository by introducing new tools and the umu-launcher to the system’s gaming configuration. Focused on package management and system configuration using Nix, the update improved game availability and launcher reliability while enabling reproducible builds and consistent environments for users. The changes centered on updating the gaming.nix configuration to support the new tooling, resulting in a more capable gaming stack that reduces setup time and improves launch performance. No major bugs were reported or fixed during this period, with the primary contribution being the delivery of a new feature for GLF-OS.
