How can I see if the drive does the overread or not? I have that option always checked in EAC (as you can see in the EAC logs I posted).

By the way, all that who copies the Japanese disks for SS and MCD I urgently would recommend to check correctness of last audio track as at offset equal 1000 + the probability of loss data in last sectors of last audiotrack is great.
For an example. From 20 disks for SS which I have copied, only at pair last audiotrack on a drive with offset +6 (EAC) was correctly copied.
I should use other drive with offest equal -1164 to extinguish huge positive offset the Japanese disks.
Forgive my English
Forgive me, but I still haven't understood if a drive with +6/-24 offset can dump correctly or not. I got the same CRCs as Themabus with a drive like that.

Topic: No-Intro datfiles (2 replies, posted in General discussion)
Would be possible to post a PSXDB derived datfiles for MegaCD on No-Intro?
I think it would be a nice cooperation, I'm already maintaining No-Intro Megadrive datfiles and I would like to adjust MegaCD naming to No-Intro convention.

Re: Perfectrip? (22 replies, posted in General discussion)
My LG CD-Rom drive is a few years old, with an AccurateRip offset of +6 (-24), and my dumps perfectly matched those of Themabus:
Would a drive with bigger offset "dump better"? Sounds strange to me.

Re: Mega-CD / Sega Saturn dumping (50 replies, posted in General discussion)
I have a question.
Some Mega CD discs have a 2 tracks layout (1 large data track + 1 very small audio track).
For these discs EAC reports a 0.00 pregap for track 2, CDRwin reports a 2.00 pregap.
If EAC is right, I shouldn't remove any pregap from the data track, since track 2 pregap is 0, should I?

Re: Mega-CD / Sega Saturn dumping (50 replies, posted in General discussion)
That's great, it would be good to have other dumps to compare!
In the meantime I tried dumped with PerfectRip with no success. PerfectRip gives me various errors on both drives, things like "injected sub between track 1 and 2", and I can't complete the dumping process with either drive. The drives (one is LG and one is Philips) are not old and in good condition, I never had a problem with EAC, so I'll stick with the IsoBuster/EAC combo.
The discs are uber-mint so the problem is that PerfectRip doesn't go along well with my drives.

Re: Mega-CD / Sega Saturn dumping (50 replies, posted in General discussion)
Since I have a couple days of free time, would it be possible to get a beta copy of PerfectRip to test it with my discs? I already talked to Vigilante @ No-Intro site, but I can't use MSN, so I couldn't contact Ipse Dixit and talk to him about it.
Anyone have a copy of PerfectRip? It would be strictly for personal use of course, no distribution whatsoever. If not possible, can anyone contact Ipse Dixit for me and explain my case? Thanks

Re: Mega-CD / Sega Saturn dumping (50 replies, posted in General discussion)
I got most of the steps, and I dumped a couple discs, but I think it's best to wait posting info until someone else can confirm my result dumping any CD I posted above.
I find little problems all the time, I noticed that one of my drives (the one I made the screenshot above with) reports this gaps
2:00
2:00
1.74
etc. all 1.74 after that
while the other drive reports
2:00
1.74
1.74
etc. all 1.74 after that
This is with gap detection method A, the other methods report totally random gaps every time

Re: Mega-CD / Sega Saturn dumping (50 replies, posted in General discussion)
sorry but were does these number come from?
Why 1700? What does mean +1694 EAC / +1724 PR?
137 2007-09-12 10:41:02
Re: Mega-CD / Sega Saturn dumping (50 replies, posted in General discussion)
Right
Offset in EAC to correct copying is +1699.
I put +1723 in EAC. Should I count the -24 or not? Is the info on AccurateRip useless?
+6 is the offset of my drive with AccurateRip info
-30 is the correction I found in the guide
-24 is the resulting offset
+1699 is the disc offset right? So should I consider the disc offset only or the drive offset too?
Should I put +1699 or +1723?

Re: Mega-CD / Sega Saturn dumping (50 replies, posted in General discussion)
Below is sector 80951. CDRWin reports that the LBA sector that should end track01 is 81099
81099 - 150 = 80949
sectors 80949 and 80950 are full of data. As you can see the first sector with zeros is 80951 (below)
I count 2092 bytes of data, so I did 2352 + 2352 + 2092 = 6796 bytes / 4 = 1699 samples

Re: Mega-CD / Sega Saturn dumping (50 replies, posted in General discussion)
I think I got the data track process. If you use CDMage with a full CDRWin image to extract the data track, you get it without gap already, 352800 bytes smaller than a data track ripped directly with CDRWin or IsoBuster.
It seems to me that EAC appends correctly the gap at the beginning of the first audio track, using the "appends gaps to next track" option. All the discs I have report this gap info with EAC:
Track01 (data) Gap 2:00
Track02 (audio) Gap 2:00
Track03 (audio) Gap 1.74
Track04 (audio) Gap 1.74
etc. etc.
From the third track on, the gap is always 1.74 seconds, while the first 2 gaps are 2 seconds.
The most confusing thing is the offset issue. AccurateRip reports my drive has +6 offset, so 6-30 = -24
Every disc has a different offsent, usually it's huge because the calculated sector which should end the first track is full of data, silence begins after a couple sectors, 6000+ bytes after the calculated end.
For example Record of Lodoss War has 6796 bytes after the end calculated by CDRWin, 6796/4 = 1699 samples
So the offset I should put in EAC is 1699 = (-24) + x ; x = 1723 right?
I get strange results, for example :
Funky Horror Band +1686
Record of Lodoss War +1723
Is it normal to have such high offsets? Are my calcutions wrong?
I think it would be great to have other dumps to compare my results with. I have the following original discs, all japanese, if someone has them too can he help me comparing?
Yumemi Yakata no Monogatari
Wolfchild
Lunar the Silver Star
Heavy Nova
Dennin Aleste
Rise of the Dragon
Prince of Persia
Super League CD
Sega Classic Arcade Collection
F1 Circus CD
Heavenly Symphony
AX-101
Ranma 1/2
Quiz Scramble Special
Vay
Funky Horror Band
Sega Games Can Vol. 1
Burai
Silpheed
Earnest Evans
After Burne III
Sangokushi III
Nostalgia 1907
Record of Lodoss War
Jikochushinha 2
Sonic CD
Shining Force CD
Tenkafubu

Re: Mega-CD / Sega Saturn dumping (50 replies, posted in General discussion)
So which software should I use to get a clean data track without gaps and without having to use "resize" tool?
Isobuster? CDMage?

Re: Mega-CD / Sega Saturn dumping (50 replies, posted in General discussion)
Another issue. When searching for the disc offset, I should look for end sector of the data track and then take away 150 sectors (352800 bytes) which are the pregap.
The resulting sector (x-150) is full of data! And the next too! The zeros begin only 2 sectors ahead of the calculated one.

Re: Mega-CD / Sega Saturn dumping (50 replies, posted in General discussion)
I have only japanese discs.
I tried dumping a disc (Record of Lodoss War) but when I proceeded deleting the pregap attached the the first track (2 seconds) i noticed that i was deleting actual data too. Both CDRWin and EAC tells that there's a 2 seconds pregap, but if you look with an hex editor the silence is less than 352800 bytes.

Topic: Mega-CD / Sega Saturn dumping (50 replies, posted in General discussion)
Hi, I need some info about Mega CD dumping
I used to mantain the No-Intro Megadrive dat (I had a 2 years pause but I'm still working on it), I found this website and since a have many MegaCD discs too I think it's time to dump them.
I looked at the dumping guide, is it valid for MegaCD too? Will the dumps be perfect without missing info? I ask this because AFAIK the disc structure is different between the systems.
Also who I need to contact to give the info to?
