). Basically, for various reasons, we picked a USB hardware ID that is designed to be compatible with Guitar Hero, and it will be Rock Band's application/game that decides on whether to recognize the guitar or not.
As I said, the limitation isn't in the hardware, but in how the game recognizes the hardware. I personally haven't tested this within Rock Band, so I couldn't say from personal experience. But, the limitation of support isn't some weird factor of the hardware: It depends on the behavior of the game software.
And no to the PS2 games being played on PS3. Like above, since our guitar is based on Red Octane's specific guidelines to be an official Guitar Hero World Tour controller, it wont add features in that fashion. Anyways, what you're running into there is a limitation of Sony's PS2 emulation on the PS3: The only controller transcription that takes place in the emulator is the adaption of Sony OEM PS3 controllers to function like PS2 controllers. Since the original Guitar Hero games depended on Controller Port guitars, the new guitars are USB as per Red Octane, and Sony does not include a USB->Controller Port function in their PS2 emulator on the PS3, we cannot add that functionality.
