It works with most existing games. In addition to games, Roger Wilco will work with ICQ so that you can chat verbally with your nongamer friends. You talk to the other players by either pressing a single key or by setting up Roger Wilco to be voice activated. You don't need a second sound card, just one capable of full-duplex audio and a microphone. Prior to registration, Roger Wilco operates in a demo mode, which restricts you to 15 minutes spent on a single tuning.
Registration is free.
You can register Roger Wilco either by clicking the Get License Key button on the License tab, or by visiting the registration page.
