I was talking to xuom2 about Redump No-Intro Conventionized datfiles several days ago, and he thinks that this is not a bad idea. So you can download Sega CD Conventionized datfile from here and post it on No-Intro

Do you mean the amount of descrambled data (garbage)? It should be different on every drive, this is the value you should use in EAC. To get disc write offset, simply subtract drive offset value from the amount of descrambled data.

Re: Introduction and help (5 replies, posted in General discussion)
Hello and thanks for the introduction I am glad to know that people from other project are also interested in Redump. And it's also nice that you are going to add psx snapshots and covers to the No-Intro Screenshot Archive - I've been searching for someone who will start this difficult work. Also I have several scans you may start with. Good luck!
About the software: a new dumping tool called PerfectRip is currently in the development stage, but until it's released, there's only one dumping method described in the guide.

Yes, that's exactly what I meant

Is this the issue of the old mastering equicment from Sony producing EDC with wrong reported values? Somewhere I read about this topic and years ago everbody though that this was the copy protection, but as far as I understand this was just a manufacturing failure.
Yes, more recent PSX discs always have EDC. The absence of EDC was just a manufacturing error.
About Alcohol: I don't want to use any proprietary formats; moreover, there is no sense in calculating checksums of such image (with data, subchannels and additional disc info stored in one file).

Hi and welcome to our project. I'll try to answer to your questions.

1) What exactly is EDC? I guess it's something like "Error Detection Code'? As far as I know, the PSX doesn't use bad sectors for copy protection, what's the deal with EDC and PSX-Games?

2) There are some disc with a data track (track 1) and an audio-track (track 2) with an length of 03:32:00. The crc of the audio-track is 7976083e. The same track occurs among different games, e.g.
- Breath of Fire IV (E) [SLES-03552]
- Music - Music Creation for the PlayStation (E) [SLES-01356]
- Dino Crisis (E) [SLES-02207]and some others. The track actually has no audio in it, it seems to be completly zero (silence). What's the propuse of this track?
It's dummy audio track, used in some Capcom games probably to avoid reading errors in the end of the disc.

3) Why not simply use some kind of image-format (like alcohol or clonecd or the like) instead of the tricky and time-consuming dumping-process? I dumped a game already in the db, and got matching hashes. Then I created an image using the lates DT of the same game. Afer that, I compared both, the dump and the image, and they seem to be identical. I you are interesset, I can post some details.
Try dumping one and the same disc with audio tracks on two different drives in CCD, then compare checksums - you'll be surprised For more info read here and in our dumping guide.
topkat wrote:
4) Before dumping I check discs with VSO Inspector, an freeware disc-testing app. On every discs, there are some errors in the first sectors (0 - 16). Is this the area where the copy protection is stored? Nevertheless I got perfect dumps with the same hashed as stated in the db, so i guess that's normal?!
Most probably this tool doesn't works with Mode 2 Form 2 sectors and reads data in cooked mode - sectors 12-15 are Form 2, and they can be read in RAW mode only.
I hope you're satisfied with my answers

Topic: LibCrypt protection (0 replies, posted in News)
With the release of psxt001z 0.20 beta 12, which is able to scan both discs and images for LibCrypt protection, it has now become an obligatory part of PSX disc dumping process. You can read more about LibCrypt protection and its detection here.
As you may have noticed, site's domain name and hosting have been changed. The new hosting should be much faster then previous, and as for domain name, old one will be back in a couple of days.

Topic: The new dumping guide (0 replies, posted in News)
The new dumping guide by Vigi is now available. Our method of detecting offset in audio tracks has already proved to be correct (for example, audio tracks in PAL and U/C editions of Mortal Kombat Trilogy now are the same), so you can safely dump every disc with audio tracks.
The next step is dealing with LibCrypt-protected discs and making new CD layout format, which, like cue, will allow to keep tracks separately from each other (clean RAW files), but will also have support of subchannels and sessions.

Topic: The offset... again! (0 replies, posted in News)
Don't dump anything with audio tracks, because we've found a method of detecting combined (read + write) offset, which varies from disc to disc, even on the same drive. New dumping instructions will be available soon.

Topic: Коррекция смещения (0 replies, posted in News)
Недавно было обнаружено, что ссылочная коррекция оффсета, которую вычислил Andre Wiethoff, автор EAC, неверна, и настоящая коррекция оффсета на 30 сэмплов меньше. В связи с этим я советую всем дождаться новой программы, PerfectRip, которая способна не только дампить как дата треки, так и аудио треки с коррекцией смещения, но и прегэп второго трека. Вы по-прежнему можете использовать EAC для дампинга аудиотреков в PSXDB, но для этого следует уменьшить коррекцию смещения на 30 сэмплов. Также, пожалуйста, не забывайте о прегэпе второго трека.
Все диски с аудиотреками, а их 87 (включая те, в которых только дамми-треки), по возможности будут (надеюсь %)) сдамплены с новой коррекцией смещения и с прегэпом второго трека.

Topic: The offset correction (0 replies, posted in News)
Recently it was discovered that the reference offset correction, which was calculated by Andre Wiethoff, the author of EAC, is incorrect and the real offset correction is 30 samples less then the Andre's one. So I advise everybody to wait for a new tool, PerfectRip, which will not only able to data tracks and audio tracks with offset correction, but also 2nd track pregap. You still can use EAC to dump audio tracks for PSXDB, but you should reduce offset correction by 30 samples. Also please don't forget about 2nd track pregap.
All discs with audio tracks (there are 87 of them, including discs with dummy-only tracks) will (I hope) be redumped with the new offset correction and including 2nd track pregap.

Как вы могли заметить, новые дампы не появлялись на нашем сайте довольно давно. На данный момент переписывается движок сайта, кроме того, была изменена структура базы, из-за чего добавление новых записей пока невозможно. Как только новая версия сайта будет готова, все новые дампы будут добавлены на сайт.

As you may have noticed, new dumps haven't appeared on the site for a long time. This is because the site is being rewrited and database format has been changed. As soon as I finish the rewrite, new dumps will be added to the site. Stay tuned!
