Start your game and when the game loads select "Options" setup your graphics resolution to match your native monitors.
You can also adjust "Game play and Sound " also if you wish to.
Go back to the main menu and select "Submarine School".
This will create your SH4 saved games folder in C:\Documents.
You do not need to select any tutorial.
