Use
GraphicsV Device drivers should make this call in order to release a driver ID that was previously allocated by OS_ScreenMode 64.
Notes
An error will be returned if the driver ID is invalid or the driver is still in the ‘started’ state (i.e. OS_ScreenMode 66 has not been called).
Before making this call the driver must make sure it has released its claim on GraphicsV and has stopped generating VSync calls.
