Are you taking PS3 submissions?

No-Intro has more problems with NES roms than that

The dat contains already checksums for the roms without header and with clrmame you use a special header xml file that tells clrmame to ignore the first 16 bytes when calculating crc32 and stuff, which is in fact the header.
There could be roms without headers, but then each emulator would need an internal list which game uses what mapper (afaik Nestopia does this).
The other "problem" with NES roms is that they contain different types of roms for a single game, like a PRG and CHR rom, but No-Intro only uses the combined romdata.

Anyway, back to PS3.
The decrypted files do not retain any of the original structure of the medium it was read from. And that is the real problem.

Uhhmmm...Xbox 1 actually has the same problem. Correct? Hence the layout files http://layouts.xbox-scene.com/

I was hoping that there would be a way for me to convert the folder into an ISO and then get the data from it through HashCalc but as we said before it would still be a decrypted ISO.

It's easy enough to replace the encrypted files in the iso with the decrypted files, however editing the iso header to reflect the new contents is a question mark (maybe nulling the hashes works? who knows, there's no iso loader to test it on), and you'd need to dump the disc as both an encrypted iso and decrypted files.

Even if it worked, you'd end up with a decrypted iso which would basically be a tarball to store the decrypted files. If an iso loader ever exists, it would have to be able to decrypt itself, so obtaining a decrypted iso is useful only for compression.

Hopefully one day, given the encrypted iso header and decrypted files (or decrypted iso), it should be possible to encrypt the files and rebuild the encrypted iso (convert from jailbreak to redump when given the encrypted iso header). And given the encrypted iso, be able to spit out the hash table in the header (or encrypted iso header for simplicity) and the decrypted iso.

A little over my head but thanks for trying to explain it.

As far as I know, the PC blu-ray drives either work, or not. So just put the game disc inside the drive, boot up the latest IsoBuster and check out whether the disc is present, or not. If it is, try dumping it easily as any other DVD, for example.

So I finally got a free moment to see if the Blu-Ray drive in my computer but unfortunately it didn't see the disc in IsoBuster.  In case anyone is interested, I have an Optiarc BD ROM BC-5500S4 drive. 

Since this thead has gotten off topic from the original question of do you or do you not take PS3 submissions, I was wondering if there is a thread on what drives work and what ones don't work.  Also, is there an active thread discussing whether or not to accept decrypted dumps from Gaia Manager.  Because if it is ever decided that they will be accepted, then I would like to know right away so I can start contributing.

These are some difficult questions, because:

• PS3 games are still rather "new" - they are not "endangered' and need no preservation
  Not many people have BluRay drives or PS3 consoles with linux and required knowledge to dump games

The easiest answer is that "yes, redump accepts PS3 dumps which are 1:1 copies of the original media, therefore the encryption must be intact."

Unfortunatelly, the fact whether such dumps are useful or not isn't really important right now. If this community is about preserving data, nobody cares you won't be able to use that data to play the game. Sounds strange, but that's what you'll get answered every time you ask.

A new backup manager has been released which is capable of PS3 Blu-ray ISO dumping:
http://www.cobra-usb.com/

Making game backups
1. Start Cobra USB Manager from the XMB.
2. Insert the game to backup. It will appear at the beginning of the games list.
3. Select it, press circle, and choose the destination device from the list.
4. You will be asked if you want the dump in iso or in the standard format. Choose the desired
option and wait for the copy to complete.

Pros and cons of iso format compared to the standard directory based format:

Pros
· Support of backups with files bigger than 4 GB on external drives is possible. Iso files with a size
bigger than 4 GB are split in parts.
· Less files on hard disk, it can help to reduce fragmentation.

Cons
· It is a less standard format for ps3 backups.
· It always requires a ps3 disc game inserted.

Perhaps this can create proper dumps.
Their solution however includes a USB dongle which is needed to actually run the manager.

Hopefully something similar will be released as freeware soon.

Hi.. thanks for letting us know about this.. I hope someone will be able to reverse engineer the software and see how it works
