Sony's PlayStation 3 console has no compatibility with the PlayStation 2 Guitar Hero controller on the system. While Guitar Hero and Guitar Hero II are fully backward-compatible through the hardware PlayStation 2 emulation in the initial North American release of the console, it was impossible at launch to use the guitar controller to play either game. Kai Huang, of RedOctane, states that they are "working on that with Sony right now – looking at how we can get all the PlayStation 2 guitars that are out there, and all the owners of them, to use them on the PlayStation 3."[185] Nyko, an accessories company, was poised to make a special PlayStation 2 controller adapter for the PlayStation 3, but put the product on hold due to technical difficulties.
