Tried it with normal 1.4 and 1.4 v7 final ultimate. It did it back on v1.1 as well using wanin original loader. I even formatted the drive and re-installed the games again fresh, still does it. Guitar Hero 3, meticallica, aerosmith and world tour all work perfectly. Using 4.0 dash with cios249 rev10. When it freezes, it freezes for a few seconds then keeps on going. Sometimes it does this multiple times per song.
