Summary	07970: sscope2: During gun calibration the game freezes
Description	To initialize the game gun calibration is required. Soon after selecting the menu voice, the game freezes.
Steps To Reproduce	Run the set, it will lament that the NVRAM needs initialization. Select "Gun Check" in the test menu. Soon after entering the gun check, the game freezes.
Additional Information	The game is marked as MACHINE_NOT_WORKING, but since it's a regression I feel it's useful to report this.
