[SCENE DE VERDAD] Lector Xbox Autentifica DVD con otro codigo

Anyway, I did an interesting experiment on the XBOX 1. I bought a GDR8163B drive, flashed it to 8050L and started modding it. I ripped a control data block from Rally sport (yes, succeeded in patching the drive to respond with the full sector contents) and saved it to FW. I created a little mod routine that overwrites the memory where the original control block is loaded from disk (just before it's going to decrypt the responses and stuff like that) with the control block data that was saved to the FW. I then tried to unlock the drive with the unlocker -> it worked perfectly, using the challenge/responses from the FW (so I unlocked 'Amped' with the challenge/responses from 'Rally sport'. Nothing really 'shocking' of course, but it was a confirmation that my 'mod' was working Smiley

I then planted the drive in a 'virgin state' xbox 1 and booted up Amped. It worked like a charm Smiley So amped worked perfectly with the control data block from Rally sport Smiley

Now, next step will be to try to get backups running with this saved control block. The problem is that the routine I patched is only executed if original xbox DVD's are inserted into the drive (the drive probably tries to read the control block from disk, sees it isn't there and then goes unto some other routine). So I have to find the 'higher' routine, that calls this subroutine. Problem is that this is done via tables and it's a real mess to find the original caller, but will be looking into that the next few days Smiley
