Re: New dreamcast dumping program (test please)

thanks, np
works good for me now
i can't test GD-ROMs atm but it reads regular CDs even through my IDE2USB

Re: New dreamcast dumping program (test please)

New version (0.4a)
Added some read options/functionality, and cleaned code a little.

-ft -ff - Fake reads: Fake read nearby before re-read to try and kick program out of read errors
          Default true

-st -sf - Step back: Fake reads after a pass to step to beginning
          Default: true

-t#     - Reread attempts: Max number of re-read attempts on a read error
          Min: 0  Max: 20  Default: 3

Hopefully this version fixes a lot of the previous issues with read errors.

edit: 0.41a suppresses some strings that shouldn't be shown on fake reads.

Re: New dreamcast dumping program (test please)

Im getting matches with the new version, but i also got matches with the old version, but comparing the two sets of matches they have BIG differences.

I know the old version worked aswell as it could but if this new version is producing completely different files when it says it matches, i think their must be a problem.

Re: New dreamcast dumping program (test please)

Please run the program to completion and try to get a match with the db. And explain how the matches have BIG differences.

Also post the dump you're trying, the log file etc.

ok i will try that with a mint easy of hell to copy disc, and see what it makes. Ill try to have a go in 1hr after tea.

Re: New dreamcast dumping program (test please)

I tried but it wouldn't rip, just hung half way, then i tried without the fake reads, and it wouldnt even start.

Re: New dreamcast dumping program (test please)

Come on man. Vague descriptions won't help at all. From that all I can give is vague advice. Problems with starting may well be the same problems that occur with the guide (sometimes you have to try the trap disc multiple times or stop start before it'll take).

What do you mean by hung half way through? An error box popped up? It sat there looking pretty? It started getting read errors all the time?

Please follow this:
Use -df to not delete the .hsh or temp section files.
If any complete sections are saved to hdd, create an md5 file for comparison with the .hsh files
Find the dcd.log so I can see your console output
Send me everything. md5, .hsh, dcd.log, your drive, the game title/region/redump entry
If it hangs, where, what was the last thing it said it was doing
Write down what any error messages say
Less is not more. Send me whatever you have even if you think it's useless. If I have nothing, I can do nothing.

Problems I have found with my own testing:
Some discs have a lot of read errors right from the start of execution, with the odd dump but largely read errors. Exiting and starting the program a few times has got some working. Once they got started they executed ok.

Some discs dump fine and dense.bin is created, but ice.exe shows that the dump has errors. I had hoped that by verifying the dump that most of those errors would go (on the premise that bad dumps due to scratches would rarely match). It seems successful matching reads don't always mean correct reads. Suggestions as to how to reduce this issue? Of course it's possible to detect when ice gives errors and try to rerip, but anything I can do at the ripping stage?

Re: New dreamcast dumping program (test please)

It hung halfway meaning it initaial dumped half the disc then hung, as in got no further, and i waited half an hour.

The other try, i couldn't even get the disc to start dumping, with the fake reads disabled.

The first time i tried on my 162c it got loads of matches, but i checked them against previous matches from v0.2  and their were huge differences like half the bytes were completely different, infact their was very little the same. And i first tried on 162d and that got some matches and they were also different to previous matches.

And I couldn't post all this info last night because redump, was not working very well.

Re: New dreamcast dumping program (test please)

A new test which I will edit further as it progresses.

TEST:

Disc = Dreamon Vol.17 (undumped this disc) have multiple copies.
Condition = A few light scratches, never been cleaned aggressively, should be good to read.
Drive = SHD-162D

DCdumper 0.2a - used so that I can compare to 0.4a
Faked my own read from 50000 with cdrwin.
Initial Dump = Section 1-49 all ok.
PASS 2 = Section 1 - read error, Section 2 - 49 MATCHES on all. It gave up trying to read setion 1, will start it again and get section 1 to read.

Re-started, fake read with cdrwin, initial dump section 1 ok, pass 2 matched, dense bin created.
Ran ice.exe all tracks ok (75) errors in last data track (in other words) a perfect dump.

No I will remove Section 2,3 & 4, and re run with 0.4a

TEST 0.4a
removed section 2,3,4 in order to force 0.4a to redump these sections only.
PASS 1 - Initial dump. All ok.
PASS 2 - Matces. On all. But guess what md5's differ from first dump with 0.2a, I already know whats going to happen smile

dense bin created with 0.4a smile

Extracted with ice, and im expecting some errors in the first track at least.

Wrong it works fine, weird. sad

The files are not the same though, so it must be some magic going on,

But at least you can relax my tests prove 0.4a works fine, but I don't know why it hang at around section 40.

Will edit to add more as the test completes.

Once I have a good dump with 0.2a Im going to check with ice exe, then im going to manually remove a couple of early bin files, and try to dump it with 0.4a. Hold tight for the results jamjam.

I was busy editting XML monkey files all last night smile hehe smile

Re: New dreamcast dumping program (test please)

BIG BIT OF WORRYING NEWS.

The dense bin with 0.2 and extraxted with ice.exe, said the usuall, no errors in all tracks except (75) in last data track, Normal.

The dense bin with 0.4a and extracted with ice.exe, also said the usuall, no errors in all tracks except (75) in last data track, Normal.

But and theirs a BIG BUTT, the 0.2a extracted tracks matched the database, BUT the one with 0.4a Track03 was not a match to the database. So definately proving 0.4a produces bad dumps.

But the BIG BUTT is why did ice exe say all was fine. Could this mean dumps we have submitted before are not fine even if ice exe said they was.

Really worrying to see ice.exe say nothing was up when infact their had been major problems. Who knows do we have some bad dreamcast dumps.

Re: New dreamcast dumping program (test please)

@tossEAC:
ICE creates a correct output thats for sure!
You would not be able to match tosec stuff otherwise also.
There is nothing to worry about  smile

@jamjam:
tossEAC is right, the newer version (0.41a tested) creates wrong output,
i have not compared what exactly is wrong for now.

Re: New dreamcast dumping program (test please)

It seems the drive returns some amount of correct data on each chunk it begins to read (probably the same amount you requested on the first read attempt, i have not looked inside the code now, so just assuming).

The rest of a chunk is most likely generated, as it is created with an ultra speed the real drive would never reach!!! tongue

Re: New dreamcast dumping program (test please)

Found a problem with the reading, will test before posting a new binary. If the problem is how I think it is, why it doesn't mess up everything is a mystery. For any who still want to test 0.41a, use -i26 as it should bypass the problem I can see.

DeviceIOControl is called to read each section 26 sectors at a time, and you seem correct that it messes up sometime after the first DeviceIOControl call.

Ultra-speed chunk generation sounds very bad, but plausible if windows keeps a record of the last successful read attempt.

Now no log is created unless the arguments are parsed correctly and it will try to dump something.

It matches db so great, but will test more and add some functions before new binary. The question is, does every multi-track dump have 75 errors on the last track? Does this number vary at all? Is there any other time ice indicates track errors where the track is actually valid?

Re: New dreamcast dumping program (test please)

ice.exe was made to automate additional steps in DC dumping (unscrambling/track separation)
AFAIR error indication in brackets is based on EDC/ECC check per sector (it determines sector nature: data or audio) and was intendet for gap managment
so there might indeed be cases when indicated number is different from 75 for good image or is 75 for bad image
75 only means that gaps are of common configuration
ice.exe was not meant for image validation
validation is performed by obtaining two matching images, preferably on different drives

Re: New dreamcast dumping program (test please)

New version (0.42a)

20110919 (0.42a)
+FIX:Read errors apparent since 0.3a
+FIX:Writing hashes to file

Have tested and found dumps to match in 0.42a which didn't in 0.41a. There may still be errors in dumping, lets hope everyone had the same problem as me  big_smile

The next version should just be for new functions, or more read fixes if necessary. Next version doesn't create/open the log file unless something will be written. Other possibilities I'm considering:

  • Send stop start  commands to drive when there are many adjacent read errors (exiting program, doing this then running program seems to kickstart it sometimes, could just be waiting awhile or some other factor though)

  • Specify 1x read speed (currently not, although sptd does seem to go a lot slower naturally)

  • Suggestions?

Fair enough about ice numbers in brackets not being definite errors and just edc/ecc checks. Knowing that, I see why the ice log that made me think of validating by ice is wrong (because the input was wrong). Each section was (0.3a-0.41a) filled with the first 26 sectors of the section, so the audio tracks after a data track had thousands of ice errors as they were actually repeated mode1 sectors from the data track. My testing of 0.3a-0.41a must only have gone so far as checking the ice log, of what happened to be single track games, oops. A complete garbage dump but it would have compressed well  lol

Thank you all for testing, information and suggestions. Keep it coming.

Re: New dreamcast dumping program (test please)

It seems to work now, at least i can notice it reads from the drive  tongue

The main problem remains though, reading the last outer edge sectors, where drives have the most problems with, and setting the read speed down will not solve this issue!

Anyway, the real benefit is you have not to wait for the drive now till it fails to try a new attempt! smile

Don't see what you can improve now, the only real solution would be to hack the firmware and let the motor drive an other route!!!  tongue

Re: New dreamcast dumping program (test please)

Dreamon Volume 16 (Europe) (En,Fr,De,Es) - SH-D162D

Everything worked perfectly on this un-dumped by me disc. I have 3 copies of this, and had never dumped this.

Matched database.

Worked much better, no read errors, process was complete at the end of the second pass.

Now to resume one of my undumped scratched discs, and see if it dumps missing sections, i hope so.

Re: New dreamcast dumping program (test please)

Here's the logs of some successful reads (matching redump), to show what I've seen using 0.42a with a "TSSTcorp DVD-ROM SH-D162C".
Observations:

  • Retrying coupled with fake reads seems to work in many cases

  • Step back doesn't seem to help much, may set the default to false next time unless others have positive results

  • Persistence pays off. The fourth and 12th successful read of 446261-549150  for house of the dead 2 matched, and the resulting track matched redump

tossEAC if you're resuming from a dump made with 0.3a-0.41a, just delete and restart, what was dumped is likely junk. Also, can you retry dumping this please? Mine matches except for the last track, which has an md5 hash of d564c50937f50a051038b0e62a8bb1f4.

Re: New dreamcast dumping program (test please)

Ill try that, in the next few minutes.

Trying now, plus i have two copies and both are mint, 100% clean. So what ring is on your disc, mine are both the same.

Section 1-49 initial dumped all ok.

Finished dumping CoolBoarders.

Got a match with jamjam's last track using his dcdumper, after extracting dense bin.

Then I removed a section of the dumped parts, but not the hashes (enough removed to entirely dump the last data track, we had the miss match on). All tarcks matched the hash's. Dense bin was created again.

Then I dumped the same section as i redumped, with cdrwin, the same section was then joined to the rest and ice exe found 1 extra error, this made the last track not match the database or what we should have got.

So then I dumped the other disc from beggining to end with cdrwin, and that extracted with ice normally and matched the dump made with jamjam programme.

Concluding the dump in the database (mine) is wrong.

On my defense, I do remember this being one of my first dreamcast dumps for redump, and im not sure if ice exe reported errors in the early days.

Ill post the full dump info when I post my dreamcast verifications and any new dumps, soon.

Re: New dreamcast dumping program (test please)

Outstanding work, jamjam!

First of all, thanks a lot for implementing DeviceIO. The new versions (0.3a+) do work for me, even on my IDE to USB adapter big_smile I've just finished my first GD-ROM dump using DCdumper (0.42a). 0.41a gave me a wrong last track even when using -i26. The 0.42a dump however matches the DB perfectly! I'm gonna submit it soon.

I have no idea if this has already been suggested, but would it be possible to put all the first pass checksums into a single file? When I dumped a disc using -i26, I had to CTRL+C it due to read errors, and I ended up with like 36.000 individual files tongue It took my computer several minutes to delete these.

Apart from that, I couldn't really find any flaws with DCdumper yet. DC dumping is almost too easy now tongue And yes, persistence does pay off:

Re: New dreamcast dumping program (test please)

Fake a read from 50000 with cdrwin then run DCDumper, works for me every time.

@tossEAC
That's a relief, I'm still trying to dump mine with CDRwin as it doesn't want to play nice sad

@amarok
Thinking about it, if you used a cut-off sector with 0.3a-0.41a, it would produce a bad dump even if you used -i26. Those versions are toxic.

Putting all first checksums into an initial file would be annoying to implement given how it works now. How about the threshold for the interval increases instead? A minimum interval of 260 sectors would produce a maximum of 1940 hash files, less if a cut-off is used. Will keep the program flexible (~0.6MB per section is small enough for those tricky discs imo), and minimise undesired behaviour.

Re: New dreamcast dumping program (test please)

Ah, I see. Well, I'm using 500 sectors per section for now, so it's not that big a problem anymore.

But I've already got another idea tongue Could you make section size variable? I mean, imagine I'm trying to dump a disc using sections of 500 sectors each, which fails repeatedly. Dumping the same range with sections of 250 (or 100, or 50, ...) blocks each however works fine. Would it be possible to tell the program to automatically switch to a lower section size once it reaches a certain number of mismatches? For example, if I try to dump a disc with -p50 -i500, I want the program to continue with, say, -i100 once the 50 passes are over instead of just aborting the whole process.

Well, thinking about it, that sounds even more difficult to implement tongue

EDIT: Okay, forget it tongue This idea is crap; I could just use the smaller section size to begin with smile Meh, sleep deprivation ftl sad
