August 7, a Twitter user named OatmealDome drew attention to the ICommonStateGetter : SetVrModeEnabled (bool) method on the Nintendo Switch console. He suggested that this command launches the VR mode on the device. The method was discovered about a year ago and described in the documentation, but it was not used. The SetVrModeEnabled function was also inactive, which was added in version 3.0.0 in August last year.
