TheSpecialist's Xbox DVD-Drive 'Unlocker' Code
>> TheSpecialist emailed us about a tool he released that unlocks an (original) Xbox DVD-ROM drive, attached to a PC, so you can access an original DVDXBOX disc from PC (using tools like Clone CD) without having to FTP to your modded Xbox.
Of course you must use the Xbox DVD-drive (it won't work with a normal PC DVD drive). Easiest to test this is probably to connect the IDE-cable of your Xbox DVD-drive to your PC and keep the cable for power/eject connected to the Xbox (if you want to install it fix in your PC you'll have to convert the cable, here's a pinout).
Also note that Windows must be able to detect your Xbox drive. Some Xbox drives (like the Philips) seem to be not detectable by Windows.
Once the drive is connected and detected you can use this tool to unlock the drive to read original DVDXBOX discs.
The Unlocker is the result of some very technical discussion over at xboxhacker.net about the Xbox(360) DVD firmware:
TheSpecialist has posted some commented code for the work he has been doing in the DVD firmware hacking thread [please remember - topics in the XBH technical forums are for technical discussion only, not speculation or questions].
The source is ready for release. I've documented it pretty well, so it can function as a kind of 'summary' of the work done in this thread. Also, I've rewritten the decryptor section. In the previously released executable, the decryption was done in a C++ routine while the rest of the code was done in Delphi 7 (it should compile with any delphi version). It uses standard RC4/SHA1 decryption, but I couldn't find the correct RC4 routine for delphi at the time, so I used a C++ source and injected the compiled code into my delphi exe, hehe Smiley Now the code is done completely in delphi, but I've also included the decryptor code in C++ in the zip file (it uses the encrypted control data block as input file). The C++ code includes the standard SHA.C and RC4.C you can find anywhere on the net.
