is there anybody who knows why? each time i try to load GH Metallica it just boots fine but when on the ingame loading screen it just freezes. i tried removing the same data with ATD i tried reinstalling original ios's i tried ciosrev13a which worked before on this game from usb loader. i tried several loaders, i even tried burning to disc. and all the time it just freezes at the same point. strange thing though as i was able to boot it before(some months ago before i had a mic or guitar, just for testing)... but last night i tried installing GH World Tour on usb and it just didn't even boot. i only had a black screen... any ideas?
