So I just noticed that if you hold your VOCALOID's box at a certain angle, you can see the serial code. (Tried to hold it at an angle where you can see what I mean, without you guys being able to read the code.)

But yeah, if you have any VOCALOID boxes, especially if from YAMAHA, I urge you to see for yourself!!
