Using these memories is easy. First, make sure you have the CSM W Driver Ver 2. Then, simply insert the memory into the driver. You'll instantly hear the cool dialogue and audio from the show. For the Fang Memory, enjoy the auto - opening jaw gimmick every time you use it. When using the Extreme Memory, listen for the unique sounds of the Cyclone Joker Gold Extreme form from the movie. As for maintenance, keep the memories away from water and extreme heat. Don't try to open them up on your own as it may damage the internal components. Also, store them in a dry and cool place when not in use. That's all you need to know to have a great experience with these awesome memories!
