Better late than never, right? It's been nine months since we first talked about the guitar compatibility patch that allows Guitar Hero III controllers to be used with Rock Band. That same patch was blocked by Activision and, we assumed, would never see the light of day again. Now, however, it's finally available. We've tried and tested it and it does exactly what we assumed it would -- allow Rock Band players to play 4-player without having to pay an extortionate amount of money for a second guitar.
Not only that, but the patch also includes the music export feature so that all (well, most) of your songs from Rock Band will be playable in the upcoming sequel. It costs $5 to export your tunes and takes up 1.52GB of HDD space. Well worth it, in our opinion.
