The first Hatsune Miku game was a PlayStation Portable jam. Japan and whatnot. However, fans could also buy an upgrade to Hatsune Miku Project Diva, called ✨Dreamy Theater✨ which ran on Playstation 3. This was the same game, but with better visuals
There was one giant catch: the PSP had to stay connected to your PS3 the entire time to play.
A sequel would do the same, except the PSP was only needed to transfer a save file. Additionally, the sequel was compatible with Sony's short-lived 3D TV.
