Hidden audio
Turn on the Dreamcast with no disc inside. When the system screen appears, go to the CD player. Insert any of the game discs. When the Shenmue disc loads, play the CD to hear the Shenmue voices tell you the dangers of putting a Dreamcast GD-ROM in a CD player. Each disc has a different voice. Disc one has Ryo talking, disc two has Fukusan, disc three has Chai, and the passport disc has Nozomi.
70 Person Battle
Finish the game and save the Clear Data to unlock "70 Person Battle" on the options screen. Disc 3 must be in the Dreamcast in order to play this mode.
Real weather
Finish the game and save the Clear Data to unlock "Magic Weather" on the settings menu in the options screen. This option allows the weather in the game to match the actual weather on that date in 1986 and 1987 in Yokosuka.
