So I am guessing to stay as close as possible to the original media we should use the encrypted version right?

Yes.

I am puzzled, how come that your other dumps are encrypted (if they match the database they have to be) and this one not?

I see that you used DICUI for your dump so I tried to do the same with my bluray drive and this time I get the same hash as you. I am just puzzled as to why the file is different when dumping from the PS3 vs from a PC with DICUI and a non PS3 OEM Bluray drive?

I do get an error using this method but I am guessing that is because I'm not using an OEM PS3 drive

Edit: I compared both files using a binary diff tool and I came to the conclusion that the ISO dumped by DICUI seems to be encrypted and the one dumped using my PS3 seems to be decrypted, I can verify that by mounting both ISO and trying to open:

On the DICUI dump it doesn't show the picture because the data is encrypted but on the PS3 dump it display a png picture just fine. So I am guessing to stay as close as possible to the original media we should use the encrypted version right?

By the way, I know the file name doesn't affect the hashes. What I mean to say is that this is the only game I couldn't dump using the exact method described here http://wiki.redump.org/index.php?title= … ping_Guide so I was afraid I wasn't dumping the right data.

I thought that the weird filename might have something to do with the fact that the dumping process doesn't start using the usual method.

Anyway I can't really be sure the dump is correct unless someone dump that game and it matches mine (or lxxxl's in which case I'll know I did something wrong)

Thanks for the help!

The existing dump has to be verified by re-dumping once again, if the original dumper (lxxxl) is able to do it.

After reading all your notes, your dump should be okay, i guess. You can provide the info if not already did

As for the problematic game in question:

The ring codes are

So yeah they do match.

I dumped it again without enabling direct disk access and choosing "Create ISO" directly from the game menu (as opposed to the video menu). I got the exact same hash:

This is a game I bought completely new and unopened. I always store my game discs carefully and in their case when not in use. The disc surface looks flawless, no scratches in view. Not a single read error when dumping.

I also tried to change the destination of the iso from the PS3 internal HDD to an external USB 3.0 HDD (FAT32 partition MBR) but I have the same issue. Press X to start the dump then nothing.

One thing I noticed is that there seem to be some encoding problem with the file name created when dumping. Japanese is often encoded using UTF8,UTF16 or SHIFT_JIS so there might be a conversion issue if multiman uses something like ASCII or ISO 8859-1 internally.

Technical jargon aside this is what I should get:

This is what I am actually getting:

When I try to FTP this over to my PC it doesn't work (I get a file doesn't exist error) until I renamed it on the PS3. I have other japanese games I dumped and they all worked although sometime the file name end up being a blank space like this:

Don't know if there's a way to specify the destination file name in multiman, if someone knows please let me know how. I would use something like dump.iso or disc.iso for all of my dump.

Does your disc's ring info match?
Can you see if there is any scratches on your disc?
When you dump your disc multiple times, does it deliver the same hash values for every dump?

I've been following the PS3 dumping guide on the wiki, the method worked for all my games except the following game:
http://redump.org/disc/67455/

My method is the following:

1. Boot multiman
2. Switch to multiman mode
3. Enable "Direct disc access"
4. Hit refresh in the multiman column
5. Under video, I navigate to the game (often labeled PS3Volume)
6. Hit triangle
7. Create Iso
8. Black screen appears with a loading bar.
9. Once over I FTP the game over to my PC for archival.

Now for the game listed above when I get to step 7. and click "Create ISO" nothing happens at all. I get no error message nothing. I tried rebooting the console and trying again but no luck.

By the way if I go to the game menu in multiman press triangle and choose "Create ISO" it seems to work but the size of the ISO looks a bit high to me for a visual novel game it's about 17GB and most VN are like 2 to 6 GB.

Is there a difference between creating an ISO in the game menu and creating an ISO in the video menu? What is Direct Disc Access used for?

Edit: Got the following SHA-1 hash when dumping from the Game menu, it doesn't match the one linked in the page above:

The size of the iso matches perfectly though:
