Hello
Firstly I would like to say for testing isos, please use
XDVDMulleter Downloaduntil beta 8 is released. It is FAR better at detecting stealth, and detects things like the link between ss and xex, and between video and pfi.
(note to ops etc, theres nothing copywrited or illegal in that rar, please feel free to check (IMG:

Also I have been looking for some technical information on the so-called badly ripped hitachi ss. I am interested in knowing exactly what ixtreme looks for to determine valid ss. (the more detail the better)
The problem with the hitachi SS is truncated responses to (at least) challenges 5 and 7.
The original ss format can mostly be described on xbox hacker, and the one c4eva uses in his firmware is just that with the decrypted table shoved in it too (to the best of my knowledge anyhow)
Decrypted table appears to have its first entry at 0x661 in the SS file
9 bytes per challenge/response. Hitachi ss will most likely have the last 4 bytes of some challenges as all zeros.
Note: i have never actually had a hitachi SS file to verify this info, so any or all might be wrong. But its how i detect for it in xdvdmulleter, so if it IS wrong, please let me know (IMG:

Wolfienuke: The correct video to be used can be worked out by looking at the PFI. 0x10 is the size of video on layer 0 before unlock (actually its a long int of the sector of the layer break starting at 0x0c, but the first logical sector on a dvd is hardcoded to 0x30000, and the number is just 0x30000 + size of layer 0 in blocks)
Anyhow, thats a terrible explaination and an unnecessary one.
If the 0x10 is 086f you need the 2724 block video file (2724*2048 = 5578752 bytes)
and if it is 0a8f then you need the 3519 block one (3519 * 2048 = 7206912 bytes)
Of course, if you ripped these video files using xbc or something, it will have ripped the ENTIRE video partition, even though the vast majority of it is padding (or security sectors on a retails disc)
If you want to see the actual size of the video files, mount the image in imgburn or something, or look at byte 0x8050, which should be the size of the video files in blocks.
Oh, and xdvdmulleter test checks the link between pfi and video, so for people who dont want to get all hex editory, you can just check it in that and if it complains about mismatched video, insert the other one. (only works on discs with a PFI)
Good luck (IMG:
