I think it is less about being associated with DIC or about active development, just that DIC does have three important differences with redumper:
1. Audio CD splits and write offset detection, which is why we only accept Audio CDs with redumper
2. There is a difference in how Redumper and DIC decide to descramble or not descramble certain invalid/unexpected data sectors. This only affects "edge cases", but it is important as some discs will not match redump hashes as a result (while the dump itself is fine, just post-processing is different). This is a design decision between the two programs, and we have decided to fix upon redumper's handling of it. DIC has changed how it handles different types of invalid/unexpected sectors over time.
3. For the new drives (Mediatek-based blu-ray drives), the leadout sectors are read using a cache read. DIC's current implementation of the cache read is prone to producing a bad dump, while redumper has fixed it (which is why these new drives have become acceptable for new dumps).

For Plextor dumps, DIC remains acceptable for dumps, with the above caveats. We therefore recommend using redumper as a "first step". In an ideal world, everyone could dump with both programs for self-verification, but we cannot force all dumpers to do this.

I shared my IRD for Tekken Hybrid (USA) for you to compare.
Make sure you have files that match exactly with the hashes listed in the IRD.

If PS3-ISO-Rebuilder does not work with it, then it is a bug with PS3-ISO-Rebuilder.
I don't know of any other program that rebuilds ISOs from IRDs, just this and NKit2

Tekken Hybrid has BD-Video content that include files that are probably interleaved or non-contiguous, and PS3-ISO-Rebuilder probably doesn't know how to rebuild this. If you created the IRD with MPF (using my program) then the IRD is correct, its just the rebuilding program that can't handle it.
You can try NKit2 to rebuild it instead: https://github.com/Nanook/NKit
This program that is currently in development, sadly I think the beta version is currently only available for download at their discord.

Sorry wrong link. Here's the UI version of MPF: https://github.com/SabreTools/MPF/relea … elease.zip

All the links are here: https://github.com/SabreTools/MPF/releases/tag/rolling

Apologies, that version has a bug. Please try with this later version of MPF: https://github.com/SabreTools/MPF/relea … elease.zip

MPF, the dumping program: https://github.com/SabreTools/MPF/relea … elease.zip

You can use my program https://github.com/Deterous/LibIRD

If you want a GUI, open MPF and go to Tools->Create PS3 IRD

is there any good method on Linux for taking redumper's output from an audio-CD-dump and checking it against AccurateRip and/or the CueTools Database?

A redump member has a custom version of CueTools that can do exactly this, not sure if it has been merged into mainline CueTools yet. It's faster and a better approach than EAC in my opinion, as e.g. EAC can't get data on the ends of some CDs.
If you want to discuss more on this topic, you can join the VGPC discord https://discord.gg/AHTfxQV
If you want to avoid discord for whatever reason, you can make a topic in this forum after you're registered.

It's a Canadian release, so I suspect there was both English and French text on the case.

Redump does not translate titles. Either "Mr. Men & Little Miss: Mr. Bump Presents: Challenge" is what was on the case/disc, or the main title needs to be in French. Need a pic of case/disc to confirm.

It was my understanding that the first 3 bytes of the DNAS ID is unique to each disc, not just pressing run. Similar to the "Disc ID" for PS3 discs.
DNAS ID began to be used on PS2 discs around 2002.
It is located somewhere near the beginning of the disc, perhaps written in the 'wobble' that Sony likes to use. In any case, it's not readable via normal PC disc drives/commands.

If your interest is in a 'lost CD locator', also checkout my attempt at a complete PS1/PS2 Sony serial index: https://sony.redump.info/

You need a PS2 console that has the ability to run homebrew programs, and run a program such as ID Dumper (https://www.psx-place.com/resources/id-dumper.455/) that will get it.
This ID is not required at all for submission.

Dumping via PC is preferred, you can get the keys after dumping via PC. Only one recently dumped disc is missing a key (temporarily) anyway.

Thanks for flashing with the firmware. You have dumper status now so feel free to submit more (See my comment on your post if you haven't already: http://forum.redump.org/post/126278/#p126278 )

This is expected and normal. One seems to be the Australian version.
You would submit them both as separate verifications.

So,  sectors in the range 299-1498 are zeroes when scrambled?

Yes, exactly like weak sectors, intended to prevent cheap CD burners from burning a backup of the disc.
Unlike with other DRM, these sectors are not used by the game.

superg wrote:

If not, we could prefill the whole range with 0x55 like we do with pretty much any other case.

As we know what is on the disc (majority of the range is read fine, number of errors differ depending on drive), I don't see why we wouldn't fix the dump to what it should be. They are not consistent C2 errors so a pure C2 -> 0x55 wouldn't mean other dumps match anyway.

I believe Redumper does not work as far back as Windows XP.

You will have to use DiscImageCreator if you want to dump on the Windows XP machine.

Hi, I have not tested MPF on XP, it's just a build of MPF that *should* work.
You'll need Dotnet installed: https://dotnet.microsoft.com/en-us/down … work/net40
And then (try to) run this: https://github.com/Deterous/MPF-Legacy/ … _win32.zip

If it's not working, I recommend running the dumping tools (DIC/Redumper) directly via command line on your old machine, and then on a modern machine running MPF.Check on the dump files (You can do this in the GUI, Tools->Check Dump).

Sarami, a verification for http://redump.org/disc/74375/ was recently dumped using 20250101 which had a different pregap for Track 4 (00:02:49). I have attached the logs.

========== TOC with pregap ==========
    Track  1, Ctl 4, Mode 1, Index0   -150, Index1      0
    Track  2, Ctl 0, Mode 0, Index0  44850, Index1  45000
    Track  3, Ctl 0, Mode 0, Index0  62592, Index1  62792
    Track  4, Ctl 0, Mode 0, Index0  68996, Index1  69195
    Track  5, Ctl 0, Mode 0, Index0  79270, Index1  79470
    Track  6, Ctl 0, Mode 0, Index0  95142, Index1  95342
    Track  7, Ctl 0, Mode 0, Index0  99005, Index1  99205
    Track  8, Ctl 0, Mode 0, Index0 101340, Index1 101540
    Track  9, Ctl 0, Mode 0, Index0 103517, Index1 103717
    Track 10, Ctl 0, Mode 0, Index0 107547, Index1 107747
    Track 11, Ctl 0, Mode 0, Index0 109585, Index1 109785

Track 4 Index 0 in _disc.txt returned 68996 (199 sector pregap)

If you have the time to, submitting logs from both tools is good. But it is not required.

The error count is still 0, as per redump.org rules around what errors get counted (invalid sync sectors are not counted in the error count). The only change is the index 1 position for two tracks.

I will see if superg can respond to your questions, better than I could.

I thought that it was the reason why Redumper was later accepted than DIC for dumps.

Redumper is new, that is why it is only recently accepted.

Both tools are dumping the exact same data from the discs, the difference is in how they are doing post-processing.
For the Might & Magic disc, they just split at different locations. DIC has identical pregap lengths for all tracks, Redumper has different pregap for Track 30 and 32. For this disc, it is due to the subcode desync messages, likely needs to be fixed (Redumper currently incorrect splits). I have fixed redump.org hashes to include the DIC splits (Tracks 29-32 have changed).

For the other two discs, they have some invalid sectors (one of which is EDC/ECC error). DIC and Redumper treat these errors differently, hence the different hashes. It is likely that redumper's method here is preferred. These are all the test cases that Redumper uses when determining what to do with invalid/unexpected sectors: https://github.com/superg/redumper/tree … unscramble

In what way did you think that DIC is better?
If you can then dumping with both can help ensure the dump is good, but Redumper is recommended for the majority of discs.

As for why the dumps are different, the logs give hints as to non-zero errors, invalid sync sectors.
There are some scenarios that Redumper and DIC deal with unexpected sectors differently.
I would have to look at the logs closer to be sure.

Also, please update your MPF to the latest version (3.3.0) which contains the recommended version of Redumper and has fixed a lot of bugs.

All discs in redump should now be (Disc 01) if it is from a set of 10 or more discs.
Roman numerals are also no longer used as disc numbers in the datname (this kind of info belongs in comments)
If you spot an inconsistency please let us know.
