is DIC really measuring the LEAD-IN and LEAD-OUT length, or are they predetermined?

LEAD-OUT length = 1st LBA of lead-in of 2nd session - 1st LBA of lead-out of 1st session
LEAD-IN length = 11400 - 150 - LEAD-OUT length

Why not to read that area and measure the lead-out/lead-in/pregap sizes according to subs? Plextor allows to read all those sectors, I guess?

I get it from subch. From 1st 0xaa to 1st 0x00 and 0xa0 is lead-out length.

Please check if title key is really correct.

what does FFFFFFFFFFFFFFFFFFFFFFFF in subchannels signify?

It's channel P. P is a flag bit that indicates the start of a track. It's almost 2s (150 sectors), but it's not necessarily 2s.

I ordered Bleemcast! for Tekken 3 by amazon.

I got a problem dumping Philips CD-i disc 'Dimo's quest' (US version) (in perfect condition, no scratch).

If disc is "Format: CD-I", Track 1 is omitted (perhaps firmware bug). For this, TOC couldn't get correctly.
This was fixed and the disc's hash that he and I have was all matched.

Yes I know. CSS.exe hasn't supported it yet.

5 c2 errors exist, but I don't know why c2 error recovering function doesn't work...

Where are we sitting with multisessional support? Have things stalled?

Bug about 2nd session multi-track disc was fixed in the latest test version (20190524 230157).
Cue sheet that admin defines was supported in the latest test version.
If admin and Jackal say 'no problem', I'll commit the code in github.

Does HashMyFiles work in your PC? If yes, I can execute it from DIC. If no, please upload your CUI tool. I can also execute it from DIC.

> ClaudeSpeed
DIC version 20180630 31122 and DICUI 1.10 is not latest. You can use the latest version.

> user7
Logs? My unlicensed PS2 disc is no problem.

sarami can you add a link to the wiki which is easily visible about the drives and dumping.

Also what is the status of PX-W1210 , PX-W1610 and PX-W2410 drives?

Not supported because these drives don't support "OpCode[0xd8]: SubCode[8]".

Some dumpers dump multisessional disc and lead-out length's is 6750 (01:30:00)

Without /c2, it reads until the end.

Yes but I meant an option to continue dumping later...

1. The disc has many C2 errors and it needs 10000 or more retries to dump the sector. Imagine that we have many of these sectors. It's not the best way to leave the drive work several days. Also, cold drive reads better! More chances with cold drive!

2. This option would be also great... If no amount of retries was set. The disc was dumped but we need to re-read C2 sectors. Maybe it's possible to code an option to allow the DIC to go to the next sector if all 4000 attempts weren't successful? 4000 with next sector etc. And to go back to these previous sectors to try 4000 attempts again and again.

With the second option we can get as many sectors as possible to go back to really hard sectors.

The best way is to combine both options to allow to read hard sectors after the drive became cold again.

Are you still challenging to dump this disc?

psx-collector wrote:

Would be very nice if DIC would try to read next hard sector if previous one wasn't dumped after all retries. It would help to dump all hard sectors leaving only very hard ones. Is it possible to add this function?

Some sectors in your CD-R perhaps can't recover, so resume function is also vain efforts I think. Please get new CD-Rs if it's possible.

People are using a Pentium II or AMD with 3Dnow to dump? Even I think that is silly.

Pentium III is also very old cpu for me... It was unbelievable that there was the person who used such an old cpu. But PIII user exists, so PII user may exist.
