I'm having this same problem. When I enable Vertical Cache for Project Diva 2, the FPS seems great but the screen is black. Sound plays fine. When I disable it, the game runs, but it is unplayable due to an inconsistent frame rate. I know my computer can handle it (12 GB RAM, 2GB Graphics Card, 3.3 Intel Processor) but I can't get this game to work for the life of me due to this stupid hiccup. I've tried 10 emulators today and Vertical Cache never works. Is there any fix for this?
