The Sega Genesis gaming system was released in several different versions during the late 1980s and early 1990s. You may have forgotten how to connect your old Sega Genesis to a television set in your home, or you may have recently purchased a Sega Genesis game system and are unsure of how to use it. The method for connecting the Sega Genesis to your television will depend on the system you own, and the TV you wish to use with the Genesis.
