[While we do not support piracy here at QJ.NET, we will always cover the news. Reporting on something is not the same as encouraging it - just like reporting a murder on the 10 o'clock news does not encourage you to kill people. A member of our forums has confirmed what was shown in the previous;y released video and shared the resources he used to do duplicate it - without giving an indepth "how-to" that might be construed as encouraging the piracy of Xbox games. It is our belief that this breakthrough is the first step in getting unsigned code and homebrew programs to be executed on the Xbox 360 and is a valuable piece of information that could positively benefit the Xbox 360 Community.]
I (NytriX) have figured out how it was done in the video.
(the video of the guy playing the PGR3 backup)
heres the instructions, I am currently playing Full Auto (Backed up).
It's a modified firmware of the Xbox 360 DVD-ROM drive.
As you (should) know, all Xbox 360 executables (XEX files) are signed by
Microsoft (with a private key only MS has). This means that if you try to change
anything to the XEX file, the signature will be wrong and the file will not
Now ... to protect from booting an exact 1:1 copy of a game from a DVD-+R,
microsoft gave each XEX file a 'mediaflag'. This mediaflag tells the Xbox 360
from which media (cd-r, dvd-r, dvd+r, dvd-rw, hdd, dvdxbox, dvdxbox360, ...).
Changing this mediaflag in XEX is not an option as it'll break the signature
(see above), so ... what's done in this firmware hack is 'break' the detection
of the disc.
(Pretty much) all the information you need is in these threads.
From what I can tell so far is that the game image will have to be patched
too - We can smell a new feature for Qwix 2 Wink
The scene can expect a hack for all drives very soon (It's currently only
Hitachi) - you can be assured that it will be released although I don't think
modchips will be any kind of business as its a pure piracy mod - no homebrew at
