I got USB Loader GX working, and all the games I install to my HDD work just fine. However, Ben 10: Vilgax Attacks (the first game I installed, if that's important) always freezes mid-game, continually playing the most recent note. I tried playing it by the disc, and it still froze. I then tried Wii Music via USB Loader GX, but that worked fine with no freezes or other errors. Seeing as it always happens, disc or HDD, is this simply corrupt save data? The freeze happens around the same time in the cutscene before the Charmcaster boss battle, if this means anything.
