This is not only easy to use, but since the time that I first hooked it up, I can honestly say that I?ve used it every time I play a game. All you have to do is push a button on the front of the unit to select the system you want to use.
Due to the ease of use and the convenience allowed by using the System Selector, it is one of those gadgets that can be used every time you play. It just sits there in the background, waiting for you to change your mind about what system you want to play. One use not mentioned by Mad Catz is ?mixing? your entertainment options with each other. For instance, if you want to play Test Drive: Off-Road 2 with the soundtrack from N2O by Crystal Method (which actually fits TDOR2 very well), you can plug your PSX in Input 1, and play the N2O soundtrack on a CD player plugged into Input 2. Then you simply depress both selection buttons 1 and 2 at the same time. Disable the music in the options screen of the game and use the CD player volume knob to adjust the music level. Voila! You just customized the soundtrack to your own preferences.
