A guide for flashing your drive firmware to read backup games. 2008 Edition. The Xbox 360 DVD-ROM drive firmware hack is currently the only modification or hack available for the Xbox 360 that allows you to play properly created backup copies of Xbox 360 games. The firmware hack does NOT allow homebrew programs to run and does NOT bypass region protection. If a video game is locked to a particular region, then it will only play on an Xbox 360 of that same region. Before jumping into this modification, it is a good idea to learn how this hack works. In the most basic form, an Xbox 360?s game protection comes from two security measures. First of which is encryption. Nearly all files on an Xbox 360 game disc as well as the Xbox 360 hard drive are signed with Microsoft?s private key. If anything in these files, even just a single bit, is changed, the signature is broken and the Xbox 360 refuses to run the file. The second security measure is media locking. The default.xex (game executable) is restricted to run only from a certain type of media. For example, all Xbox 360 games are restricted to run only from ?Xbox 360? media. Before the firmware hacks, if you were to copy an Xbox 360 game and try running it from ?DVD R DL? the Xbox 360 would obviously see that it wasn?t ?Xbox 360? media and refuse to run it because of the media restriction.
