New dreamcast dumping program (test please)

[tossEAC]

I just buffed a disc a bit to much, has one deep mother of all scratches in it, so i put a load of displex polish on the edges of the disc, and buffed only for a bit, but that polish is powerfully sticky, and after only a bit of a buff, the disc started turning into jello (jelly) it went all soft and started warping in my hand, but funnilly enough I just sprayed on some other polish and buffeed the displex off and now its normal again. jello

BTW Jammy, I was using a SH-D162D before, but have just had a try on 162C, its a completely different ballgame, but I remember when i first started dumping dreamcast using the 162C, a lot of my dumps had the odd byte of data wrong, like FF instead of FE, and I think I saw that before when i used it.

Also is that SH-D162B (Black) any good for dreamcast, because my xbox/360/dreamcast drive i use the most is on its last legs, mainly becuase of dreamcast dumping recently. So i was thinking of replacing it with a dreamcast only drive, I dont casre if it doesnt do 360, just dreamcast. So let me know if the black one works on Dreamcast.

hi, jamjam

i tried DCdumper.exe 0.2a but it would just crash on my PC (XP SP3)

usually programs would use SCSI Pass Through Interface (SPTI) to communicate with drive
(SCSI_PASS_THROUGH_DIRECT / SCSI_PASS_THROUGH_DIRECT_WITH_BUFFER)
it has least problems
and you can get handle with CreateFile, so only letter is needed - it shouldn't matter if its USB or ATA or SATA
there are good examples in Kris Kaspersky's book
http://forum.mobilism.org/viewtopic.php … ;view=next
(look for RAW reading through SPTI
there should be precompiled examples and .c files that came on CD with the book somewhere on web too,
but if you can't find those PM me and i'll send them to you)
and on Truman's homepage
http://www.cdtool.pwp.blueyonder.co.uk/workshop.htm

good luck

@themabus
Thank you, I'll look into it. My choice of akrip was just because it was the first thing I found that worked, but it seems people are having problems.

@tossEAC
I will try your suggestions if necessary, fake reads particularly sound potentially useful. No I will not be your xml code monkey bitch
I have a black drive but I think it is C version.

[tossEAC]

Ok, xml monkey bitch is not needed

And BTW I got that disc I turned to jello to dump perfectly using your amazing tool, thats one off the list, it was Urban Chaos btw.

New version (0.3a).

Usage: DCdumper.exe drive_letter [options]

Code: Select all

20110917 (0.3a)
+No longer uses akrip32, now DeviceIO (SPTD)
+No longer uses startstop.exe, now DeviceIO (Load device)
+Section hashes stored to file as successful reads are completed (better resume function)
+Log file created (mirrors console)
+Pass drive letter, not scsi id

Thanks themabus, much cleaner now.

[themabus]

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

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

Code: Select all

-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.

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.

[jamjam]

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.

[tossEAC]

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.
