Hatsune Miku: Project DIVA is a music game created by Sega and Crypton Future Media for the PSP, featuring the virtual idol Hatsune Miku. Danielcatu noticed various beta-differences in the early screens and videos, as changes in the HUD and in the clear screen. Some comparison screens with the final version can be found in our forum.
Thanks to Danielcatu for the contribution!
