you need to tell us why it doenst work first. Im gettin so tired of playing the noob guessing game. GUESS WHY MY CRAP WONT WORK? how bout some info about dvd's whats installed, everyone elses super mario galaxy works.
Why is everyone obsessed with patching? DO NOT PATCH UNLESS YOU HAVE TRIED A 1;1 COPY FIRST. Patching is to fix problem games, not to throw everything at it. Even then, you are supposed to patch to 249, not 30.
