Title: TOSEC ISO - Amiga
Post by: tomse on April 17, 2014, 01:36:04 PM
I've been redirected here by Crashdisk (whom takes care of alot of Amiga TOSEC).

I'd like to help out in this section.
But I'd probably need some longer discussions with what gets added,

reading from an other post I take it is Aral with whom I need to discuss this with.

Hi tomse,

I'm sorry that nobody replied yet and i'm not sure if I can help you much more with ISO information. AFAIK, TOSEC-ISO started not only has a cataloguing (datting) project for optical disc media but also a dumping project. Dumping discs has been a complex subject for long, with several groups proposing different methods (and claiming the "perfect" result) in addition to the old ripped versions. The iso section, maintained by idoru, had its own method used by dumpers such as Maddog (for Dreamcast), which submitted their work to create dats. Once, two copies of the same disc were dumped (and matched via md5) it was marked "good dump". With idoru and others gone as well other/newer dumping projects, that part almost stopped. Most of us that remain here are more interested in the cataloguing / datting existing software than dumping media.

That said, we are obviously interested in saving optical media too. We have had some talks and Cassiel (and others) even started adding a few extra ISOs I think. I'm not really the right person to help you on this but, do you have undumped media that is missing in our dats?

IMHO it should work just like the other branches, if there are unrenamed files they just need to be added to the right dats (or new dats) using the TNC names. The problem is deciding which dumping method to use. Ideally we would/should at least dat/use isos created with the best or "standard" method at the time or even add several. The main issues are the fact that this "standard" has been changing over time and is disputable. The previously dumped sets used our old method, if that is "perfect" for a specific system I don't see many reasons to just drop them. Other idea would be to just add several "formats" (obtained with different dumping methods), much like what happens in TOSEC main branch with disks et al. This creates some problems regarding size (having the same software in different formats) and if followed, should be done much more carefully than what happened in TOSEC, to avoid spreading a lot of uneeded roms and garbage.


Maybe your post can start a nice discussion about this, if we can get Cassiel, Aral, Maddog or anyone else willing to do so to discuss these ideas :)

Thank you for the response PandMonium.

In my offer to help, I had 2 ways in mind.

Yes, I have CD's to dump/add which aren't in the DATs

But also help with the maintenance (when I get more experienced in the TOSEC naming, community etc) of the ISO part of the Amiga.
Or without stepping on someones toes, be the maintainer if there's the need.

I'm a total TOSEC noob, in the sense of naming, proper dumping etc, but I promise to do the best that I can.


To get in, on the discussion around which kind of format should be used.
There are, as you say, plenty of formats to choose from.
ISO might in the most cases just do it. But I've seen quite a few CD's on the Amiga that also contain sound tracks.
so a better format should be used.
cue/bin/wav could cover that which has been used a lot a decade ago.

but to follow the technology of the day, perhaps mds or mdx (generated by i.e. Daemon Tools for Windows) could be a good candidate, though I have no idea if there are any programs on MAC or *nix that can make that format, it ought to be multiplatform these days with more Linux and MAC computers see the light of the day.
The problem with mds / mdx is that it's limited to Daemon Tools, and perhaps a small selection of other tools, where ISO/BIN etc is a standard.

Of course if some of the other people already have some good options, I'm open.

The TNC part is not a problem. Everyone is a noob before learning how to do it...
As for the ISO details, it is highly technical and I can't really help you with an informed opinion. Still, some good solutions would be to check if those discs were already dumped and which is the state of the art format to dump Amiga ISOs. Maybe someone over EAB can inform us about this. The goal would be to dump the discs using such knowledge and add them to their DBs and then properly name and dat that stuff in TOSEC-ISO collection.

Some ISO experts are needed here. Just dump the discs with some random process/tool is not the ideal way (still, if the disc is rare and dying having a backup in a good enough format would be nice).

The dumps I've seen for Amiga are somewhat mixed.
Some are ISO, but most are CUE/BIN/WAV, there are some other formats too (nero's nrg etc)

The CD's for Amiga are regular DATA and sometimes DATA/Audio (ISO9660 / Joliet).
I have yet to find any copy protected CD, and I don't think I'll see any, in which case ISO / CUE/BIN/WAV will do the trick.

But I'll see if EAB has some input.

No, dumps are not mixed. All extractions are made ​​in ISO format (for Amiga). Other formats are homemade CD (digital distribution), the format has not been changed because it does not make sense to convert.

I'm not talking about the ones in TOSEC, but the ones not in TOSEC, a good sample is what is on the EAB file server.

With the limited but still useful info, both old and new dumping to cue/iso/wav seems to be the way to go.

old: https://web.archive.org/web/20060508111746/http://startaq.ath.cx:10080/wiki/guide
new: http://redump.org/guide/cddumping/

I'll start sorting through my stuff soon, so we can use that as a reference on naming, precedure for adding hash values etc.

So lets say I have already I already have some cumped ISOs and ready to hash them; I did a quick look what there are of tools, but didn't seem to find something that constructs the output format. (hashing to md5/sha1/crc isn't an issue here, but you might already have a tool for this?)
Also skimming through some of the sticky posts here in the forum I didn't see any posts how to upload these dat files.

and how is it about verification?  is it done by a second person with a second media on a second drive? or is it fine with a second media on a second drive?
(I have a stack of doublet CD's hence the question)


Title: Re: TOSEC ISO - Amiga
Post by: Maddog on June 22, 2014, 01:34:54 PM
Uploading dats can be done by putting your stuff in a filehosting service and PM'ing the link to Cassiel, since he's the one responsible for final dat output usually. That's what I do with my Dreamcast stuff.

The old TOSEC ISO method is IMHO quite sufficient for Amiga CDs, since they contain no fancy protections or any other form of CD standard abuse.
The Redump method is used by the Redump group. Not willing to start much of a discussion about it, since there were endless wars over their perceived (and self-declared...) superiority, so I'll just say we currently don't have any discs in the dats that were dumped by Redump standards. And there is an even newer dumping method from the Trurip group.

As for verification, with the old TOSEC ISO method and rules it was allowed to add a data-only disc to the dats when dumped by a single person. This was not allowed for discs with CD Audio tracks, since these were proven to be rather more error-prone when dumped.
Verification was always a 2nd person, dumping a different disc (and not even knowing what were the "target" checksums that the other dumper had submitted, since those were never public). Somewhat strict, but we got our share of cheaters and just plain erroneous dumps and this was the only method we could think off, since noone could declare "verifying" something he hadn't actually dumped. Or even unwillingly dumped incorrectly for any reason (eg using wrong settings in EAC or a drive that didn't support overreading into leadout)

As for hashing, ClrMAME Pro does a good job for me.

Hope I have helped. :)

@Maddog you certainly have (helped), thanks :-)

The only concern I have are the gaps between audio tracks.
but I guess I'll have to make some tests with the different methods.
But that's only neccessary if/when I get to a mixed CD.

Below, the last method of extraction known by TOSEC :
http://wayback.archive.org/web/20100326210649/http://wiki.toseciso.org/guide
We should test the method with some discs CD32 which are already known and after the upgrade to the newest software...

sounds great.. I have a couple of CD32 games, atleast one of them have audio (Pirates Gold!)
I can't say for the other CD's atm as I haven't tested them

but atleast there is a great start now with lots of options given both here and in the EAB forums.

so far, I'd like to thank you all for your input, and getting behind me on this :-)

Agreed Maddog....  Remember though with the old ripping way we all had to have a very old Pioneer drive, if i remember correctly it was a Pioneer DVR-106D v1.07 - RPC-1 + 2xDVD-R + 12xRip or earlier or the CRC's would never match.

Title: Re: TOSEC ISO - Amiga
Post by: Maddog on June 28, 2014, 02:32:52 PM
For Pioneer drives all models from 105D up to 111D were fine if I remember correctly. I was personally using 111D. 112D was bad, ability to overread into leadout was removed for that model and afterwards.
And Plextors were fine as well, unless my memory is failing fast. Getting old...kinda funny to think I was first involved into CD dumping 10-ish years ago...
Title: Re: TOSEC ISO - Amiga
Post by: tomse on June 29, 2014, 08:35:05 PM
just a small update from my part.

I've confirmed my setup by dumping already known disks and comparing the hashvalue to the ones in TOSEC.

CD's tested :
Pirates Gold! (CD32) (data+audio)
CU Amiga Super CD's 13, 15 and 21 (13 has both data + audio)

All CD's got imported into my TOSEC using RomVault.

I've commited the dump dat generated from Thalions CD's (eab post) to Cassiel, and awaiting some feedback.

at present time I've started dumping some of my CD's which will await the above mentioned feedback, no need to do the job twice if I made an error :-)


Now I'm sitting with a Dual CD case.
Each CD is named differently..
Code: [Select]
In-to-the-net (199x)(company)
out-of-the-net volume 1 (199x)(company)

so should they be named as such? or should they be named as the title on the cover
Code: [Select]
In-to-the-net (199x)(company)(disc 1 of 2)
In-to-the-net (199x)(company)(disc 2 of 2)

Title: Re: TOSEC ISO - Amiga
Post by: Maddog on June 30, 2014, 08:23:42 AM
For your naming issue:
What we use normally is the full release's name, not the individual discs name, which is put in the [more info] flag at the end when deemed important.
Example using RE2:
Resident Evil 2 (Disc 1 of 2)[Leon]
Resident Evil 2 (Disc 2 of 2)[Claire]
The Leon and Claire names are on the discs, so it is proper in this case to add the info to the filename.

So, what I think is correct on your case should be (assuming that I understood correctly that "In-to-the-net" is the cover name for the entire release, Disc 1 is called again "In-to-the-net" while disc 2 is called "out-of-the-net volume 1") :
In-to-the-net (199x)(company)(disc 1 of 2)
In-to-the-net (199x)(company)(disc 2 of 2)[out-of-the-net volume 1]

This conveys all necessary info in the most elegant way, according to my understanding (and usage so far...) of the TNC. If Cassiel has to add/correct anything, follow his opinion.

Thank you, it makes perfect sense to do so :-)

Exactly what Maddog said...  :)
Title: Re: TOSEC ISO - Amiga
Post by: tomse on July 02, 2014, 01:52:32 PM
thanks for the confirmation, I've already prepared the naming as Maddog suggested :-)

I've run into an issue with one of my CD32 games
Super Skid Marks 2.

When dumping the ISO + Wave, the same way I dumped Pirates Gold (used for testing, Pirates was valid in tosec) I get a difference in both ISO and Wave files.
I played one of the wave tracks and saw a 2sec difference (longer) in the TOSEC, compared to the one I dumped using EAC.

I checked the file timestamp of the CD (data track) and one of the CDs (there are 2 CD's with same title) in TOSEC and they match.

Can it be that the ISO in TOSEC isn't dumped using EAC, and what is your suggestions to handle this?

Personally I have 2 options, replace the one in TOSEC, or add this one, perhaps with an extra comment [EAC] but I'd prefer to hear how any of you would solve this, seeing as I'm the newest member of the team :-)

EDIT:
v0.99 eac prebeta = screwed up --> gap after track 1 is wrong.

Yes all tosec-iso are dumped with wrong gap

It looks like there's an issue here..
@Crashdisk, do you still have CD's? and can you do a few comparisons using the newest EAC please?
Title: Re: TOSEC ISO - Amiga
Post by: Aral on July 04, 2014, 09:47:04 AM
Now that the database is lost there is no way to verify who originally dumped this title.  The version dumped would have probably had a different ring code than the version you have.  Sega Saturn titles had many different ring codes ensuring sightly different crc's.

Versions of EAC after 0.99 beta 5 will not replicate the required CRC's you require to successfully dump this title. 
Title: Re: TOSEC ISO - Amiga
Post by: Crashdisk on July 04, 2014, 10:05:16 AM
It would be useful indeed but we must not forget one of the parameters depends on the CD drive himself : offset correction
It would also be interesting to add in the signature of your profile, list of CD drive you use. From my side, I have to repair my equipment before they can help you :-/
Title: Re: TOSEC ISO - Amiga
Post by: tomse on July 04, 2014, 02:06:17 PM
@crashdisk no worries mate the CD's I have, I won't get rid of (call me a hoarder :-))

@aral well I'm using the latest EAC which is 1.0 beta 3
What kicks me off is that my dump of Pirates Gold! (CD32) is the same as in TOSEC vs my dump of Super Skid Marks 2 isn't

Well. lets see what the next input will say..
I might try dumping on my portable too to see if there are any differences.

Title: Re: TOSEC ISO - Amiga
Post by: Aral on July 04, 2014, 03:24:30 PM
Tomse by using that drive and that version of the software your CRC's will never match the CD's already dumped.

Im afraid you will have to get something like this off ebay before attempting to dump anything else.

Post by: tomse on July 04, 2014, 03:33:34 PM
that doesn't explain why it works with Pirates Gold!

The ISO (data) part of my Super Skid Marks, isn't the same as in TOSEC.
Which it should compared to my other ISO dumps that actually work.

Post by: Aral on July 05, 2014, 01:10:20 PM
Trust me tomse, we spent hundreds of hours testing different drives and settings back in the day and the combination myself and maddog describe in previous posts is the only combination that will give 100% correct crc's every time. 

This afternoon i thought i would have a muck around with some different drive / software combinations on some Sega Saturn, IBM PC and Sega Mega CD multi track Cd's.  I tried a BDR-207DBK, DVR-221LBK, DVR-215D, DVR-111D and a DVR-108BK.  I tried the latest EAC and 0.99 beta 5.

Without boring you with detail only the DVR-111D and DVR-108BK gave the correct CRC's with EAC 0.99 beta 5.  The rest of them gave partial CRC matches.

Title: Re: TOSEC ISO - Amiga
Post by: tomse on July 06, 2014, 09:26:57 AM
alrighty,

have you tested against the DVR-108 too as it should be the same drive as the DVR108BK which just has the plastic in black instead of white.. or..??

since these are drives with IDE interfaces have they been tested with USB / IDE adapters ?

and do you have a description on how to perform these tests, or do you just re-read multiple times and see if the checksum is the same.

the reason why I'm asking is that it might not be viable to aquire optical drives second hand and believe they work perfectly, so continous tests on more modern drives should not be abandonned. I have access to a good number of different models I can make tests on.

Do we have a compiled lists of drives already tested? imo it would be beneficial to have such a list to show people.

(it's been a while since I paid that much for a DVD writer  ;D)

Post by: Maddog on July 07, 2014, 08:53:25 AM
For Super Skidmarks, there appear to be two different versions.
I was able to use the wayback machine to dig out some long dead info:
Quote
Super Skidmarks    2.2    1995    Acid    Guildhall Leisure          GH01 10 AUG 95    Different audio tracks    •
Super Skidmarks    2.2    1995    Acid    Guildhall Leisure          GH01 21 APR 95       •

http://web.archive.org/web/20060501140739/http://startaq.ath.cx:10080/list.php?sys=1

The one marked as "different audio tracks" is shown with a green dot there, so this is the verified one. The other one is red (unverified) and it's CRCs were only known by [idoru] as he was maintaining the ISO dats. No chance to retrieve these long lost checksums anymore.

You'll have to check your ringcode. If it matches the verified dump, then we got a dumping method issue in our hands and need to research further what's going on. If it's different, then obviously checksums SHOULD be different, at least for the audio tracks. To determine what's going on with the ISO, it's usually useful to do a binary comparison, this immediately illustrates bad dumps (usually just amount to a sequence of 0 bytes at the end of the ISO that's missing from the dump) or a different data revision (differences at the actual data). If needed I can do this, as long as the new ISO dump and the old verified one are given to me to compare.
Title: Re: TOSEC ISO - Amiga
Post by: tomse on July 07, 2014, 10:38:44 AM
Thanks for the info Maddog.
I'll redump when my DVR-111 drive arrives to see any changes.

I have a contact who has a good stack of CD32 media, amongst them is Super Skidmarks 2 I'll see if I can do a comparison there, when/if the sun permits ;-)

EDIT: ok, for some reason (likely to what Aral says), perhaps because of a hot drive? (it was the last CD I dumped) the checksums from that day till now differ.
I guess I'll need to re-dump my cd's again and make sure they have the same checksum.

the "GH1 21 APR 95" is the disc I have. The iso dump today is the same as the database, though wave files differ still. I'll wait till the drive arrives to verify.

I've received quite a good amount of cd images from someone. What is the policy in relation that we get such dumps, but the source is unknown?

There are also several images in the eab file server. How is the policy to convert these to iso/cue and add to the database?

Most are cue/bin,  ccd/img etc...  I'm only considering the data-only media here, not the data/audio.


EDIT: And, how do we handle Unofficial releases of something? i.e. if a CD32 is released as .nrg ?
(here I would take it as-is, but I have to ask :-))

EDIT2: what do we do with mixed ISO's like these?

I just received my Pioneer 111D drive.

Since I've had to set that up on a different computer, I went through the ripping guide again.
I spotted something I didn't change on my primary workstation.
Which was the "Append GAP to next track" setting.

I changed that on my primary workstation, and I've dumped Super Skid Marks several times now, both with newest version of EAC and the 0.99 prebeta.
The result of these dumps are the same, and have the same hash value as what is in tosec.
This was using the Pioneer BDR-S08 and v1.10 firmware

@Aral if you want, I can make some extensive checking on this drive (I just need to know which procedures you want me to do)


on the other hand.
Track 2 of Super Skid Marks doesn't have the same hash value as the one in TOSEC using the Pioneer DVR-111D drive I just received. This has been testing using both versions (latest and prebeta) of EAC

Same goes for Pirates Gold! Track 2 is different from what's in TOSEC with the Pioneer DVR-111D and the BDR-S08  (Append Gaps to next track)

Using "Append Gaps to previous tracks" on both drives Track 2 of Pirates Gold! have the same hash as in the database.

So to sum up there are inconsistencies! All these dumps are with EAC 0.9 Prebeta 5,
Dumping Track 2 of super skid marks with the DVR-111D is different from the database no matter which setting.
Dumping Track 2 of super skid marks with the BDR-S08 is good when using  "Append Gap to next track" (also OK with newest EAC)
Dumping Track 2 of super skid marks with the BDR-S08 is bad when using  "Append Gap to previous track"
Dumping Track 2 of Pirates Gold using "Append Gap to next track" The dumps of both drives are bad.
Dumping Track 2 of Pirates Gold using "Append Gap to previous track" The dumps of both drives are good.

All the other tracks are good, it's just track 2 that causes issues.

So after seeing this what would be a proper course of action be to do now?
* Should we reset the verified marker for the Images that have audio tracks?
* Is there something wrong in my setup?


Make note that people might not want to spend £50-£100 to aquire a DVR-111D or other drive that has been tested and approved, just to send in their dumps,
so donated dumps w/audio might be incorrect.

Post by: Maddog on July 20, 2014, 09:54:59 AM
Damned if I can remember correctly anymore the fine points of EAC...
IIRC, versions of EAC up to a point had a bug? different way of calculating? at gap detection which would indeed alter the hash of track02.
I don't really remember in which version this was fixed, but dumps of TOSEC were done using the old versions. Anyone using newer versions would come up with different hash, just like you mention. Since the "error" wasn't involving any data loss, it was decided not to redump everything from scratch.

Not sure which version I was using back then, a little voice in my mind says 0.95 beta 3. I am unable to check anymore since my old dumping computer which still has the relevant programs installed is back home in Greece and I am living in Dubai now. But it might be worth a shot finding and using 0.95 b3.
Or talking with Aral and Cassiel about the possibility of finally redoing some dumps using the latest EAC, I can't make a call for that.

For previous post questions: unofficial is generally handled "as-is". See some of the existing "Unofficial" dats in TOSEC ISO.
As for converting dumps existing in other formats, we have never done this. All dumps in TOSEC had known dumpers and judging from amount of errors I have seen in random dumps from the Net, it is at least a risky business to take any random image and convert it. Totally impossible for discs with CDDA, but even the theoretically simple data-only stuff, sometimes wouldn't convert to an image identical to the verified one. I'd go with "quality-not quantity" approach and just ignore any such stuff.
Redump were quite loose in their acceptance of "dumps" so they ended up with several scene rips in their dats that proved different from a dump done from an actual disc. At least in PS2 dat from what I hear :)
I have personally found one in the PSP as well. Ape Academy 2 (http://datomatic.nointro.org/index.php?page=show_record&n=0634&s=62). NoIntro has it marked as a correct dump in their PSP dat, using a Redump "dump". I dumped the same disc, came up with a different result and after getting crazy thinking I made a bad dump it was finally discovered that someone had used a scene rip made with an older tool and submitted it as an actual dump.

Thanks for the info.. I'm glad that you've had some issues too (that it isn't just me that has issues  ;D )

Untill Aral can give an answer too I'll put it to rest for a while. I don't want to do unnecessary double work if I'm doing something wrong anyway.

The 0.95 Beta 4 is still available, but as you say -and from what I've read around the forum- there are issues with some of the versions. Which ones, doesn't seem to be properly confirmed, other than the guide Aral made, which states to use the 0.99 prebeta.

I think I'll need to ask the amiga community to redump if possible, for the images that are in the EAB fileserver but not in TOSEC. There are quite a lot of goodies there.

:-)
