TOSEC ISO - Amiga

[tomse]

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 :-)

Wow... when it rains, it pours

You fancy coordinating getting these dumped too?

[tomse]

absolutely awesome :-)  thanks

[Cassiel]

Cool... remember to coordinate re audio tracks (if relevant) so everybody dumping the same way.

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.

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.

[Maddog]

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...

[tomse]

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)


[Maddog]

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.

[tomse]

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

[Cassiel]

Exactly what Maddog said... 

[tomse]

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?

[Aral]

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. 

[Crashdisk]

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 :-/

[tomse]

@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.

[Aral]

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.
