In the arcade version, pressing the Start button just before the first fork in the road on the first level of the game will result in a message being displayed showing Yu Suzuki's name as well as the month and year of the game. To access this text on a later build of the game, (known as Ver. B), a high score has to be registered as "YU", and then by pressing Start during the Stage 2-3 transition.
