"We haven't had a Guitar Hero homebrew clone of late. There was that Guitarra Gero back in September, but now here's something new. GuitarStar v1.00 comes from French coder festi.
Since this is the first release, there's no changelog. That's all well and good, because even though it's still in its early stage, it already has one big feature: song compatibility with Frets on Fire! Yes, you can add your own Frets on Fire music!"
