Neil Fore contributed to libretro/RetroArch by developing and refining input overlay systems, focusing on touch and analog input reliability across embedded and mobile platforms. He implemented features such as analog stick recentering zones and persistent touch pointer roles, using C and C++ to enhance input accuracy and reduce user friction. Neil addressed overlay memory management by optimizing image reuse and load times, and improved input handling by introducing platform-specific constraints and outlier detection. His work combined configuration management, driver development, and performance optimization, resulting in more stable, maintainable input overlays and a smoother user experience for RetroArch’s on-screen controls.

Jul 1, 2025July 2025 — libretro/RetroArch: Enhanced touch input stability and input-overlay reliability. Delivered two main improvements: a speed cap on touch pointer tracking with fixes to input_overlay_track_touch_inputs, and a refactor to assign a single, persistent role per touch pointer across polls. These changes reduce input jitter, prevent pointer-role conflicts, and improve consistency across devices, improving user experience for on-screen controls and pointer-driven UI.

Mar 1, 2025March 2025: Delivered stability improvements to overlay input handling in libretro/RetroArch, focusing on overlay devices (lightguns, mice, pointers) and platform-specific input constraints. The work reduced input misreads, improved UI responsiveness when overlay buttons are pressed, and established safe platform restrictions to minimize cross-platform edge cases. Overall impact: smoother overlay interactions, fewer input-related regressions, and a maintainable code path for future input refinements.

Feb 1, 2025February 2025: Delivered Precise Analog Stick Re-centering for libretro/RetroArch, significantly improving analog input accuracy and user experience. The feature refines the input driver's recentering logic by computing touch distance and placing the center at the first touch or within the recenter zone perimeter, delivering more precise and intuitive stick behavior.
