Is /f usage in /t mandatory ?

No, it's using by default.

I tried MotoRacer 3 (USA) and found that 1st and 2nd twin sector was hard to read, thus it's difficult to get the identical hash.

Backwards reading hashing for range B sectors
- no identical CRC-32 found
- hashes inconsistency is not reliable enough to help detect the range of twin sectors

Thanks test. As Jackal says, it needs to reread each sector until the twin sector is obtained.

I found the explanation at CDFreaks. https://web.archive.org/web/20070615215 … es-blunder

And Jackass writes the memo in the uploaded file.

Notes:
------
I have successfully used this utility to backup XIII CD's 2, 3, and 4
Please see my other program BGEScan if you wish to backup Beyond Good and Evil CD3
You might like to try the following data
Title Sector Start Sector End
------------------------------------------
XIII CD2 281170 281424
XIII CD3 274371 274625
XIII CD4 287915 288169

I'm not sure these ranges are correct.

Nemok wrote:

Then narrowing the suspected range to 287500-288500 since:
- 287000-287500 always gives D7F637B0
- 288500-289000 always gives BB08138A

If these sectors matches the forward-sectors, it's not tages sectors.

2023-12-12 08:54:34

PLEXTOR can get the identical hash when uses /f (cache delete), but sometimes returns non-identical hash.
ASUS can't get the identical hash even if uses /f.

2023-12-12 05:52:37

I tried to dump at several time from 329687-329947 using /r
1. CRC32: 26F4EEC3 (ASUS)
2. CRC32: 200728C2 (ASUS)
3. CRC32: 0F5D94C2 (ASUS)
4. CRC32: 5DFECCCA (PLEXTOR)
5. CRC32: 3779DF3B (PLEXTOR)

These are always different hashes. Did Jackal really obtain identical hashes?

Nemok wrote:

That's why I wanted to try "/r".

"/r" generates only the forward-image using backward reading.

I dumped Moto Racer 3 (USA) http://redump.org/disc/31578/ with /r. As a result, I found it that 329693 ... 329946 are different sectors. But Jackal says "Disc has 260 twin sectors in range 329687-329947".

Question: Twin sectors of the Tages are always 260 sectors? If yes, where is the evidence to show that it is correct?

You dumped http://redump.org/disc/34669/ . How did you get the hashes with duplicated sectors inserted into the disc image?

What is the current state of Tages support ?
The github page mentions that DIC "can read in reverse, but specifications are not decided".

I don't know how redump.org stipulates that twin sectors be preserved.

It crashed by memcpy.

Normally it's supposed to just be a separate 5 byte buffer that's passed to the ReadMKI function anyway, so I'm not expecting much to be written there.

5 bytes = 40 bits. DVD has 40 bits key of CSS, so I've expected that UMD also has some kind of 40 bits key (media key?).

SPK is SPecial Key? SPecific Key?

I am probably overthinking it, but do try the ReadMKI function with the SPKGetMKI address (if it allows you to write to kernel memory like that). At worst it'll just blank out assembly instructions of the module and crash

The result is no error and no crash but buffer is all zero bytes except buffer[2].

Yes. I've already comfirmed that this func can be called and succeeded.
