One running marketing theme Sega has been using with rhythm game Hatsune Miku Project Diva is the number "39." This can be pronounced "Miku," just like the character's name.
In PlayStation 3's Hatsune Miku Project Diva Dreamy Theater 2nd, you'll find the number 39 in the most unlikely of places. The game download file size, for example, somehow managed to be 3939 megabytes.
How did Sega get this exact number? Twitter user Madoka_Park claims to have analyzed the game's files and discovered 43 megabytes of padding in the form of a dummy file.
Investigating further, Madoka_Park found that dummy file consists of the number 39 (actually hexadecimal 0x39) repeated over and over.
Try it for yourself... if you're a big enough Hatsune Miku fan to pay 3,900 yen (yes, they even priced it with 39!) for what is essentially an expansion to a PSP game.
