If I understood you well, you think that this file "book.bin" is a database of games which you can view with CSA shogi. If it is that, it does not have anything of it. "Book.bin" is a file which makes it possible the engine "Bonanza" to play the openings correctly.
When you play against SCA, it will answer instantaneously if the moves that you make in the opening are indexed in this file "book.bin".
I hope that I could render comprehensible me (excuse my approximate English: I am French:-)).
