In Nancy Drew: Treasure in the Royal Tower, the Professor has video recorded the hallways. To watch her footage, press play on the camera (camcorder). The battery pack dies before you can finish watching the video, so take out the battery pack and place it in the dock to the right. Return to your room and change the time to the following night. Back in the Professor’s room, the battery has had time to recharge. Pick it up and place it back in the camera. Press play to watch the second half of the video footage.
