I have no knowledge of hacking but all you guys are asking where is the hdd. Well i am guessing that the entire hack is on a king kong backup that has modified files. So that means his 360 probably had a flashed dvd drive or modchip. This leads me to believe that at first all hacks/homebrew will be loaded off of a burnt dvd like how homebrew is on the dreamcast. I still don't know if i should believe this or not, although I hope its real. But even if it is real I am guessing you will need to have a flashed dvd drive or modchip and since I just got my 360 in Dec I am going have to wait a whole year before I even attempt it because I dont want to lose my warrenty.
