Jan 1, 2026January 2026 focused on delivering UI/UX refinements, stability improvements, and packaging/maintenance hygiene for libretro/RetroArch, delivering measurable business value through a smoother user experience and easier ongoing maintenance. Key features delivered include UI and device/index formatting improvements with on-screen error handling and safer label lengths, core list linking, improved disc control icons, and broader safety with label length protections; system/config cleanup and removal of dead menu driver code; and subsystem architecture enhancements by increasing the maximum subsystems to boost core quitting/loading robustness. Major bugs fixed include menu input stability improvements (toggle bindings and resume triggers) and protections against accidental removal of port 1 device index, menu-disabled mode fixes (build/config dir handling and initialization safeguards), and input/render edge fixes (AtD bitmask and bitmap font offset). These changes collectively improve reliability, reduce session crashes, and simplify future maintenance. Technologies and skills demonstrated include C/C++ development, UI/UX engineering, input handling, config management and packaging automation (autoconf), and subsystem/core lifecycle redesign.
