is writing his name and all the characters appear. Wait until
a demo of the game appears. Go though the demo and the opening
FMV sequence will appear again. Go though that and go though

indicated by the PlayStation2's time setting. For example, if
you set the PlayStation2's time to 11:30 a.m., it will be bright
and sunny in the game. If it is 7:00 p.m., it would be sunset.
If you set the time to 10:30 p.m. it will be dark outside.
