This disc points 335260 sector as the position of root directory, but this sector is all zero byte, so dic can't read the directory record and can't detect the protect.
I think the correct position of root dir is 21 or 22 or 23 or 24.

Can Isobuster read the directory correctly?

Updated test version. Test and upload the log please.

BTW, why isn't there "Errors count" in "NEC PC Engine CD - TurboGrafx-CD" ?

Updated.

        /c2     Continue reading CD to recover C2 error existing sector
                        val1    value to reread (default: 255)
                        val2    0: reread sector c2 error is reported (default)
                                1: reread all (or from first to last) sector
                        val3    first LBA to reread (default: 0)
                        val4    last LBA to reread (default: end-of-sector)
                                val3, 4 is used when val2 is 1

----

it rereads all the sectors now, not only the ones with C2 errors?

As I already said in PM, the c2 error report of the drive isn't completely reliable as far as I see the log of A Murder of Crows, so I check all sectors if even one c2 error exists. But when val2 is "0", only rereads sector c2 error is reported.

Why not to rollback to the old error correction

The old logic saw the sector all-bytes matched for two consecutive as the correct sector, but it could get the incorrect sector all-bytes matched for two consecutive.
So my bad disc couldn't get the all recovered sector. Your disc is nothing but getting the correct sector by accident.

I will recheck --- b) Dump with "/c2 /q /p" parameters --- later again.

I confirmed that 0xd8 with 08(Main+C2+Sub) couldn't get the pregap sector properly if first track is the data.
If resolves this, when reads the pregap sector of the first track, it has to use 0xd8 with 02(Main+Sub).


EDIT:
Sorry. 20171102 version wasn't uploaded. Uploaded as 20171106. I confirmed my damaged disc is recovered all using this version.

FUA is not matter. Reading speed is down when reads minus from current. It is the same as /r (reverse reading)

This is misdetection. I'll fix it if possible.

Unfortunately, most of the logs didn't actually write out with this error, so I should have just attached the minimal set the first time... But what I got out of it, is attached here. The disc dump (that is clean) doesn't match either of the 2 existing ones, sadly, so I can't use them as baselines to compare against.

Thanks.
It looks like that the directory size of the 200204 is incorrect because 1st directory record of the next sector shows current directory. Please try the latest test version.

C2 errors was fixed at all
But please dump at least twice (if possible, using different drives)

It clearly looks like that there is little number of the reading times, but in case of my bad condition disc, reading times was correct. I don't know why now.

LBA[000077, 0x0004d], unknown mode: 62
LBA[000078, 0x0004e], unknown mode: 62
LBA[000079, 0x0004f], unknown mode: 62
LBA[000080, 0x00050], unknown mode: 62

Fixed and added MSF in EccEdc.

 :
LBA[321285, 0x4e705], mode 2 form 1, SubHeader[1](IsInterleaved[00]), [2](ChannelNum[00]), [3](SubMode[00]), Form 1, [4](CodingInfo[00])
LBA[321286, 0x4e706], unknown mode: 62
LBA[321287, 0x4e707], unknown mode: 62
LBA[321288, 0x4e708], unknown mode: 82
LBA[321289, 0x4e709], unknown mode: 62

I don't know why several sectors are shifted..

I confirmed some SCSI drives. I believe PX-32TSi also supports 0xd8 and reading lead-in/out.

sarami, it looks a little better now, but still weird.

Fixed.

Shall i maybe move all the correspondences concerning this disc to an extra topic?

I don't think it needs.

i don't have to run an extra dump with /raw switch, as it doesn't do anything extra, or do you need it!?

I had forgotten that /raw originally only works the multi-session disc. Added that show the warning message when the single-session disc is dumped.

Sorry for the late response, I didn't see your PM till you mentioned it here. Uploaded the logs you requested:

DIC Logs
subdump Logs

Disc is completely shot, getting lots of errors.

Please try to use /f option or change the reading speed or change the drive.

Also uploaded the logs for King's Quest V, another disc giving problems though I ordered another copy.

King's Quest V Logs

I don't know why the volume descriptor isn't read. Is this ISO9660 disc?

Uploaded test version.

Main channel is shifted by 30 samples forwards

Only this disc? or all disc you have? I tried the same option with MegaRace of 3DO but Main channel was shifted correctly with offset.

There are 7 titles in "Psychic Detective Series", 2 titles in "Ms. Detective".

No, I mean, are there only 9 DAPS titles total, where 1 CD is compatible with PC-9821, DOS/V and FM-Towns?

sarami wrote:

These 5 titles exist FMT, PC9821 (not PC98), DOS/V, MAC.

Mac releases also have DWDC codes? And all 9 titles are compatible with 4 platforms, not 3? PC-9821, DOS/V, FM-Towns _AND_ Mac?

You mean dccs(Datawest Compatible CD System), not DAPS(Datawest Active Picture System)?
https://ja.wikipedia.org/wiki/DAPS

DAPS is supported by original, remake, win95, "Ms. Detective", that is, all titles. dccs is supported by remake, and "Ms. Detective", that is, 7 titles.

And sorry, perhaps mac release may not exist. As the supported machine name, there are PC-9821, TM-TOWNS, DOS/V in manual.
That is, wikipedia is perhaps incorrect.

2) Were all 9 titles released for FMT before PC-98 and DOS/V?

Original version (http://redump.org/disc/23566/, http://redump.org/disc/27268/, http://redump.org/disc/23567/, http://redump.org/disc/23563/, http://redump.org/disc/24204/) These 5 titles exist only FMT.

Remake version (http://redump.org/disc/33798/, http://redump.org/disc/33799/, http://redump.org/disc/27760/, http://redump.org/disc/25039/, http://redump.org/disc/23570/) These 5 titles exist FMT, PC9821 (not PC98), DOS/V, MAC.
wikipedia: https://ja.wikipedia.org/wiki/%E3%83%87 … 83%88#DCCS

Vol1 - Vol. 5 of Win95 is the migration of remake version.
Final Solitude of Win95 is the migration of original version. (Final Solitude doesn't exist remake version.)
wikipedia: https://ja.wikipedia.org/wiki/%E3%83%87 … 88#Windows
BTW, Vol. 3 and Vol. 4 was migrated to PC-Engine, Mega-CD too.

"Ms. Detective" is released with FMT, PC-9821.

Is it safe to set FMT as the "main" platform for all 9 titles?

I think so.

F1ReB4LL wrote:

5) Was it the only series of releases for PC-98? suruga-ya lists some titles separately for PC-9801 and PC-9821

suruga-ya is incorrect.
