Thanks, V.
Agree with pablogm123: match finding is very fast.

Excellent tool, V.
Is there any chance of adding an option to output any found fragments to a new file(s)?
e.g.
findcrcs <file> <size of window> <crc> <outfile>

Thanks. 
You can use CDMAGE to make multiple track images into a single image for burning.
That's not really what I'm getting at since I typically burn the images to disc without converting them as you suggest. There's no real reason to, is there?
However for discs with mastering inconsistencies you'll need the subs and a clonecd cue sheet to burn them properly.
Are such discs accurately identified in the redump db? I understand you can use sbi2sub with the provided .sbi attachments for libcrypt encrypted discs to generate the necessary subs for burning. Putting libcrypt aside for the moment, isn't it conceivable that some discs already in the database (e.g. Saturn and PSX) won't ever playback on real hardware? I must add that I've never had any problems on anything I've played to this point.
So what's going on with the dump I mentioned earlier? Is it a mastering inconsistency, a series of bad dumps, ImgBurn issue?

Re: Redump discs with multiple data tracks (6 replies, posted in General discussion)
Does this mean there could be a problem with the accuracy of the dump information currently in the database? Or is it a problem with ImgBurn in this instance?
To clarify, it's ImgBurn throwing out the said errors and not PerfectRip.
Thanks.

To explain, I attempted to dump a redump-verified image to a single bin/cue file using DTLite/ImgBurn. I usually do this for checking for inconsistencies when converting NonRedump images to separate tracks (e.g. cloneCD, single bin files etc). I usually notice the above errors on multi-data tracks when incorrectly calculating pregaps/sectors lengths using isobuster. Assuming it is correct, would playback be an issue given all the errors ImgBurn is spewing out?
The above output was taken from http://redump.org/disc/17355/
(It's unlikely that 4 separate dumpers failed to correctly dump the said disc)
On a broader note, should redump images playback without issue on hardware capable of doing so?

Topic: CDGroup Benchmarks (0 replies, posted in General discussion)
Below are some results I obtained using jamjam's CDGroup utility. Although intended for internal use, I thought they might prove useful for reference purposes.
Conditions were as follows:
Dataset: PSX (all regions)
Discs were regionally grouped where available
Demos were appropriately grouped with full releases
Multiple point releases were grouped
Multi-disc titles were appropriately grouped
Audio tracks were compressed post-split (ape -c5000)
t7z was replaced with 7z 7.25a, 64 bit (-mx9 -m0=LZMA:d1024m:fb273 -mmt2)
Time stamps and file attributes were scrubbed from all of the archives for consistency and cross-compatibility.
All discs conformed to Redump standard
Merged sets adhere to Redump.org naming convention with the following alterations:
Merged set containing 2 or more regions have no regional suffix assigned (those containing only 1 region retain their regional suffix as before)
Multi-disc title within a merged set has the disc label removed
Multi-point release within a merged set has the version label removed
Merged name: USA>Europe>Japan
Of the chosen sample data, 881 discs were grouped down to 197. Each title in the dataset below is suffixed by 3 numbers: combined torrent7z size (MB), cdgroup size (MB) and the ratio between the two (in red).
Summary
Raw size (GB):

Topic: PakkISO update (source?) (5 replies, posted in General discussion)
I have some suggestions for improving PakkISO and was hoping the author of the program would be willing to send me the source code to make a few changes. My ideas are based off of what I've been accomplishing via shell scripts up until now and, more recently, some of the work jamjam has been doing with CDGroup and 7z generic.
The suggestions are as follows:
- Update the compressor to 7z 9.25A
- Update the 7z cmd switches to: a -mx9 -m0=LZMA -mmt=2 -ms=on -mf=off -mhc=off -mhe=off -mtc=off -mta=off -mtm=off (the last two forego the need to use rmdtrash.exe as it instructs 7z to not store any timestamp information)
- Scrub file attributes pre-compression
- Generate and store a generic hash (.hsh) file with each pack containing bin/cue/iso name, size and sha1
Example:
Input:
Dino Crisis (Japan) (Track 1).bin
Dino Crisis (Japan) (Track 2).bin
Dino Crisis (Japan).cue
Output:
Dino Crisis (Japan) (Track 1).7z
Dino Crisis (Japan) (Track 2).ape
Dino Crisis (Japan).cue
Dino Crisis (Japan).hsh
Another option could be to output just a single file: Dino Crisis (Japan).7z which contains the previous output (using 7zCopy) but as follows:
Track 1.7z
Track 2.ape
*.cue
*.hsh
The controller would rename all binary contents pre-compression to generic track names and update cue sheet entries accordingly to allow renaming without a repack (updated archive file name in this instance). I'm just toying around with ideas for a cross-compatible update which outputs files that are easier to maintain than at present.
Thoughts and comments are welcome.

Thanks for the link, pablogm123.
I didn't know about interleaving sub-channel data re:MDF...

Re: Dumping PSX discs with known errors? (4 replies, posted in General discussion)
I'm aware that the errors are referred from CDmage. Thank you for clarifying!
My original disc does have some light scratches; the two instances of "Unreadable sectors" as reported per IB appear, then, to be unrelated if what you're saying is correct re:If you are dumping from original media, you should extract the disc in IsoBuster without problems!
By your logic, and precluding the absence of an original disc, am I correct in assuming that it's impossible to accurately convert a non-standard image (e.g. .ccd, .mdf etc.) to .bin/.cue format if there are already errors present?

With regard to:
How is it when I mount the said image (DTLite), I receive "Unreadable sectors" when I try to extract the same track in IB? No matter which option I select (replace, skip etc), I cannot recreate the corresponding hash values.
I achieve the same result using the original disc as well.
I'm curious how people dump these images to begin with.

Re: Redump Problem (PSX) - Help??? (2 replies, posted in General discussion)
Thanks for taking the time to explain, mock. The checksums now match those submitted by other users.
I only have 3 playstation games; I'll endeavour to submit those I have over the coming days now that I have a better understanding of what's going on.
(:
Would someone mind updating the wiki guide to perhaps make a clear(er) note of this? I'd never of figured out the correct combined offset had you not have explained what was going on.
I've also just realised that I've posted in the wrong section of the forum (sorry).

Topic: Redump Problem (PSX) - Help??? (2 replies, posted in General discussion)
Hi, guys.
I'm having trouble getting an accurate dump of the following:
World Soccer Winning Eleven 2002 [SLPM-87056]
http://redump.org/disc/12751/
Having followed your dumping guide to the letter, I cannot get the checksums of the audio tracks to correspond to those submitted on your site nor does the sector value of the data track.
Software:
EAC 0.99 prebeta 5
Iso Buster 2.8.5
Optical Drive: Pioneer BDR-206D FW 1.06 (Correction Offset = +667)
As per your setup instructions, I determined the pregaps using EAC (2 Seconds across the board per track).
Using IsoBuster, I then calculated the combined offset from sector 130458:
20 rows (320 bytes)
+80 samples
Write Offset: -587
(see attachment)
Redump has the sector listed at 130457 for the data track (not 130458). If I extract the data track between sectors 0-130457 using Iso Buster, the checksums match fine with those submitted on your site. However, the sector view indicates the length to be 130458 (as per attachment).
Why the discrepancy?
Finally, when I enter the combined offset value into EAC under Drive Options (+80) and dump the audio tracks, the checksums don't correspond to those submitted on your site either.
Why again?
I'm genuinely intrigued to know what's going on.
