DiscImageCreator

[reentrant]

Hi sarami,
   At first I'd like to thank you for such great tool. I was also writing a similar one on my own in the past but I see your one is much more powerful. So I though about dropping my tool and helping you with DIC. I have already made some fixes on my own in DIC and I don't want them to be lost. Is it ok for you to move the project to some place like github where we can easily sync our work?

Hi.
Created repo. Is this ok?

Yes, it's good. Thanks.

First link - >1GB DIC error log for https://redump.info/disc/14386/ from GreyFox. First time he tried to dump it with DIC, it crashed with AppCrash message and the log was also more than 1GB, second time it haven't crashed, but the log was as huge.
Second link - subdump. S-W channels are filled with 0xFF, channel R has data and the last 50 sectors are filled with different data, even the P and Q channels.

I'm wondering what's so special in subdump that DIC can't do, are subdump's subchannel dumps reliable or is it just a different methodology which in the end is not 100% perfect?

From what I understand C2 bits only account for 2352 portion of disc sector. So the obvious question it how to reliably dump the subchannels?

I found such topic:
http://club.myce.com/f61/subchannel-issues-214939/

Listing the different protection schemes for the 8 subcoding channels:
Channel P: no protection - can't be fixed?
Channel Q: 16-bit CRC - who is computing this CRC, and compare the resulting value against what?
Channels R to W: RS - to protect the data in the subcoding channels R to W, a (24, 20) Reed-Solomon error correction code is used. To improve the burst error correction capability, 8 times interleaving is added to this error-correction system. The first two symbols in a PACK have additional protection with a (4, 2) Reed-Solomon error correction code.

As for P & Q - proprietary (Truman-IpseDixit) correction algorithms - do you know what's their algorithm?

I've noticed that if I dump using DiscImageCreator cd W: gamedir\game 4 then dat file is empty but if I use DiscImageCreator cd W: game 4 then dat file is fine. Anyone noticed this?

The slash is causing the issue.. someone else mentioned the same problem in a chatroom yesterday

Could you tell me the following log of the cmd.

I've already fixed 20160411 test version. I replaced this version as release. And I uploaded 20160602 test version. (fixed crashing of the tr3-mac, but the hash doesn't match according to GreyFox)
