Here's your answer.
It's a fanmade PC version of a Project Diva engine. It's not too advanced, but at the moment the gameplay is exactly like the PSP version. It is a little strange to set up and install, as you have to change your regional settings to China, but from there it's smooth sailing. Just make sure you have all the things necessary(Direct show and directx files, etc). I think you can edit the files to change when and how often you hit the notes in game, but I haven't tried it. If that's correct, I assume you can even make your own music and put it in, along with videos.
