I agree. While there is a room for improvement, C2 parameter is useful once and for all.

Another suggestion / wish list:

-A function to either generate automatically .sfv, .md5 and .sha1 files (for the splitted tracks and the monolithic image) or output to a .txt files the CRC-32, MD5 and SHA-1 hashes of the dump, for the individual tracks and the single file image.

Examples of .sfv, .md5 and .sha1 files I am speaking about:

If you add hashing, I would prefer that they can be outputted in clrmame format for using in the newdisc menu.

I think that F1REB4LL's suggestion of error correction be used so we can be sure that the cache is defeated on re-read.

:EDIT:

Got testing results back from other person with different HW revision 5224a.

DIC w/C2 is now functioning properly with his drive. =]

There should be more logic in determining, if the EAN sector between tracks belongs to the previous or to the next track. https://redump.info/disc/2664/ -- here it doesn't belong to the previous sector, as usual, but to the next one. And it's common for PCE games. So it's better to compare the last pregap digit with the rest of pregaps and choose the one closer to the rest of pregaps, in this case it's "0" everywhere (00:02:00), so it can't be "4" (00:01:74).

So what is the recommened version now? WIP2? Or isn't it tested enough yet?

wip2 is work in progress yet.

F1ReB4LL wrote:I still think it's better to read all the sectors "as is", make a list of incorrect ones and reread them after all the sectors were read. That should give better results, since when you read 1 sector many times, it may return cached results and when you reread all bad sectors in a batch after you have dumped the whole disc, you can be sure no caching is involved

Fixing your ways. But as a result, I think that the reading number of times is not so different.

PC Engine Disc is very irregular. I buy it and check it.

Nope, you don't understand

EAN sector itself is a replacement of one of the usual subchannels sectors. And when you see it between 2 tracks - it can be either the last sector of the previous track or the first sector of the next track, you can only guess

So you should compare it against the rest of the gaps. For example, you have such EAN sector between 2 tracks and it either belongs to the previous sector (and the gap is 00:01:74) or to the next sector (and the gap is 00:02:00) => you need to compare both cases against the rest of the gaps. If all the other gaps end with 00, then this one is obviously 00:02:00. If only the first gap ends with 00 and all the rest (at least 2) end with 74, then this one is obviously 00:01:74. Hope, you've got my point.
You don't need to buy, I can give you .sub examples.

Thanks all.
WIP3
http://www.mediafire.com/download/u0olo2c51f2qv13/
change: c2 error fix logic.
add: output hash(crc32, md5, sha1) to .dat file

>EAN Sector
Please wait.

Could you post the Unicode release of WIP3?

Wishlist:

-An option to override (for certain CDDAs with data pushed to the lead-out, such as the example posted below) the standard offset correction proposed by AccurateRip.

-This text can be removed, no longer applicable.

c2: Check C2 error (Only CD)
Take twice as long

-To remove the [TRACK x] sections of the generated ccd file, and the CATALOG entrie as well. These sections aren't needed because the gaps and EAN/MCN are already defined by the actual subcode when burning the disc using the RAW DAO 96 mode of CloneCD. And add one CR+LF to separe each section, to read better the generated file.

Where is file created? In case of windows7, C:\Users\<username>

Posted: **Fri Oct 25, 2013 10:49 am**

Files are created in the expected folder, c:\temp.

===============================

I have to specify the absolute path of the output file so that discimagecreator will work OK. Previous releases worked OK with relative paths.

===============================

I strongly think that the hashes of the single file image and the overread part should be stored into a separated .dat file, so that the .dat can be used to submit the dumps as is it, without cutting/deleting anything.
