Thank you for playing JR EAST Train Simulator. A malfunction occurred after the Steam client update on September 11, 2024 for the Zuiki controller, which has been compatible with JR East Train Simulator since May, 2024. Although we took action to resolve the issue in December of last year, after the Steam client update on Monday, January 20, 2025, the mascons do not work properly when playing again by selecting the Zuiki controller from the controller settings.
