Input lag in arcade game machines can ruin the gaming experience, but there are several effective ways to troubleshoot and fix it. First, check the connections between the control panel and the main board—loose or damaged wires can cause delays. Next, test the monitor's response time, as older CRT displays often perform better than modern LCDs for arcade games.

Updating or replacing the game's firmware can also resolve software-related input lag. Additionally, inspect the joystick and buttons for wear and tear, as mechanical issues may slow responsiveness. Finally, ensure the power supply is stable, as voltage fluctuations can affect performance. By addressing these factors, you can significantly reduce input lag and enjoy smoother gameplay.
