Arcade manufacturers employ several techniques to ensure consistent light gun sensitivity across all units, delivering a seamless gaming experience. First, they use standardized components and precise calibration during production. Each light gun undergoes rigorous testing to verify its responsiveness to on-screen targets. Advanced sensors and firmware are fine-tuned to maintain uniformity, while environmental factors like ambient light are accounted for in the design. Additionally, manufacturers implement strict quality control checks to eliminate variances between units. By combining high-quality materials, automated calibration, and thorough testing, arcade games achieve reliable and accurate light gun performance for players worldwide.
