@Edness has managed to do some big things now, but wasn't able to post here for now. The update is here: https://www.psx-place.com/threads/re-hacking-the-singstar-dlc-encryption.49222/ Now we should be able to at least decrypt the DLC, although there's some work left to add custom songs.

I did find some documentation about the library now and it was just different names for the same library. I noticed that it had support for ciphertext stealing etc. as padding, so that might explain the filesizes. Many of the encrypted files have odd filesizes that are not divisible by a normal...

Alright, that sounds like it could be the one I'm looking for. I noticed it's called libsecure though instead of libSceSecure. Is that the normal naming convention, or could there be some other library as well? @DeViL303 : Information about the PSHome encryption might absolutely be of interest...

I've been looking into the Singstar DLC encryption in another thread, and noticed an external library being used called libSceSecure.sprx. I can't really find any information about this, so I'm wondering if anyone here could tell me what it does. All I could find is that a PS4 version exists...

I have some potentially helpful updates about this now. I've been able to compare my song files to ones from another PS3. We have 49 songs in common, 19 of them have the exact same file size. Out of these, 4 of them have almost identical contents, except for the last 256 bytes of the files...

I've managed to decrypt the keys.edat file using TrueAncestor EDAT Rebuilder, but the content of the output doesn't make any sense to me. The first bytes are "12 EC D9 0B 2E F9 56 3F" and I can't seem to find any similar file format. There's also some repeating information in the file, so I...

Sorry that I forgot about the simpler way to do this. It should be enough to just change the <User>x</User> tags inside /dev_hdd0/game/BCES00011SINGSTARFAMILY/SongCache/SongCache.xml to a user id that exists on your system. For those who want to move their songs to a new console and don't need...

Try to remove all users over 4 and then change /setting/user/lastCreatedUserId in xRegistry.sys to 3 and then create a new user. If that doesn't work, look for the guides about resetting the counter by formatting the disk in a PC, add 4 new users and then copy back all the game folders to the disk.

Well, it was a while ago I did this, so I'm unsure how I changed it. The easiest solution should be to format the drive in a PC to get a clean xRegistry.sys and then just copy the game folders back to it. However, I do think I managed to change /setting/user/lastCreatedUserId in xRegistry.sys...

This has to do with that the Singstar DLC is attached to the PS3 User ID instead of the username. If your removed Singstar user had the ID 2, the new account would be ID 3 or something higher. Without editing the system files, this User ID for the next user will just keep increasing. What you...

The PS2 discs are most likely linked from the Singstar app through the /dev_hdd0/game/NPEA00374/USRDIR/Data/PS3/LegacyPS2Discs.pkd file. To get your custom songs working that way you would need to edit that file, but how to do this is another thing we don't know. According to a previous post...

Seeing this post, I made an interesting discovery with my new PS3. I now have one of the same songs as @mattwookie has. Pack0_10000J.pkg.drm is a-ha - Take On Me and the filesizes are different. The filesize in this screenshot is 61369583, my filesize is 61369536 and in my SongCache.xml, the...

I now have access to another PS3 with some Singstar DLC, so I've been able to do some more experiments. Unfortunately I still don't have any duplicate songs, so I can't yet compare the .pkg.drm files. What I now know though, is that it's just the PSID that matters for the encryption, that the...

I don't think the hashes would tell us anything that we don't already know. The files are encrypted in some way, but what would be interesting to know is if the entire files are encrypted or not. To see that we would need to compare the contents.

I'm sorry for not getting back to this sooner, but I haven't had the time to look any more into this until now. What I said in the first post about the PSID being part of the encryption was that the songs work if the PSID is identical to the original console, and that it doesn't matter if I...
