System: Sega Genesis
Game Title: Coach K College Basketball
The Sega Genesis game Coach K College Basketball contains a hidden Animation Viewer. I was not able to make a Game Genie type code yet. To access the new menu, pause the game to bring up the 'Game Paused' menu. Turn on the following PAR code, then press either Up or Down, and disable the PAR code. Lastly, press C to enter the menu.
