Homebrew [Download] SEEDconv - seeddb.bin generator for use with Decrypt9

d0k3 · Jul 15, 2015

Instructions: Get the file at nand:/data/<console-unique>/sysdata/0001000f/00000000 (only available on FW 9.6, thus only available with a hardmod or on EmuNAND). Copy this to some directory on your PC together with seedconv.exe. Then just drag and drop 00000000 (or multiple different 00000000 files) onto seedconv.exe, and a working seeddb.bin should automagically be generated. If multiple files are used, the seeddb.bin will contain all unique seeds from all files.

If you drag and drop one or multiple seeddb.bin files (rename them first, must not be called 'seeddb.bin'!), the unique seeds from them will also get added to the newly generated seeddb.bin file. This works also when drag and dropping alongside one or multiple 00000000 files.

Download: https://github.com/d0k3/SEEDconv/releases
Source Code: https://github.com/d0k3/SEEDconv

You're on your own for getting that nand:/data/<console-unique>/sysdata/0001000f/00000000 file - but as I said, you need a hardmod or EmuNAND to dump that from your 9.6.0+ NAND. Also, no seeddb.bin releases in this thread, please, as I fear that won't go well with GBAtemp rules. Share that stuff somewhere else

. The game specific seeds, by the way, are not console unique, as confirmed by Shadowtrance. However, your 00000000 file may be, so be careful.

... and before I forget about it, thanks go to everyone who helped solving this mystery, including @Shadowtrance, @mixups, @key1340 and @k8099.

Sorry for my ignorance but what is the purpose of the seeddb.bin file ?

Decrypting games that use the new 9.6 SEED crypto. Without it, there's no decrypting them.
So no making cia's, editing etc from them.

You need it to decrypt some specific titles, such as the Puzzles and Dragons Z demo. Without it, no decryption, CIA conversion, etc... of these title is possible. At the moment there are only a handful of these titles, but there may be more in the future. Edit: Ha, Shadowtrance was faster

SEEDconv works fine
I did tested 2 SEED Crypto games Bloo Kid 2 (Europe) and Pony Pets 3D (Japan).

In Bloo Kid 2 .exefs and .exheader was able to correctly decrypted.
However I think .romfs.xorpad is invalid, due I can not be found Magic "IVFC" in romfs.bin.

Pony Pets 3D has the unusual NCCH Flags 00 00 00 00 01 03 00 20
(Bloo Kid 2 and anything has 00 00 00 01 01 03 00 20)
In Pony Pets 3D .exheader was able to correctly decrypted.
However, since when decompressed bigger than 1GB code.bin generated a exefs in ctrtool, so I think .exefs_norm.xorpad is invalid.

Nope i did bloo kid 2 earlier no problem. romfs n all.

This is how you get the discussion to the correct place

. Bloo Kid 2 seems to be okay (see Shadowtrances reply). Can you further test the decrypted Pony Pets 3D and give a more detailed description? To be pretty honest, I am not that experienced with that stuff (believe it or not

), so I don't know what the big code.bin could mean. It does sound like a ctrtool problem rather than a SEEDconv or Decrypt9 problem, though (remember, the SEED crypto is pretty new), so I'd first update that to the newest version.

Shadowtrance · Jul 15, 2015

Your thread, you move the convo here from elsewhere.

haha Plus I'm tired... need coffee!

As for the code.bin thing @mixups did you merge the exefs xorpads? I assume there was a norm one and a 7x one? they need to be merged with MEX.py THEN use it with the encrypted exefs.bin. (not sure if you did that or not, just pointing it out).

Wow that is really great. Thanks @d0k3 and @Shadowtrance , great work, as usual...

Don't thank me, i didn't do shit except be a guinea pig testing random stuff. haha

Testing is an essential part

I wouldn't say that I would have gotten anywhere with this without some help

By the way, here's the list of SEED crypto titles from the other thread (found by Shadowtrance):

Ooooh I missed this whole thing. So that's how they do preloading.

From there I can only tell that it looks like it doesn't use 7.x crypto (= no slot0x25keyx needed). However, I know there's a specific and rare kind of crypto that cannot be handled by an O3DS (yup, updating won't be of any use). Maybe that's that. Needs confirmation, though.

Additional info:
In theory you'd need a slot0x0AkeyX.bin file for that, but don't bother searching as that doesn't exist and even Decrypt9 couldn't handle that now.

liomajor · Jul 15, 2015

Why Hardmod only? I can simply use my xorpads to decrypt every emunand version.

Maybe N3DS only games?

Valid point for old3ds users, not so much for n3ds users.

~~Backup emuNAND, update your n3ds emunand, extract it, decrypt it, restore it.~~

You can't get to 9.6

Shadowtrance · Jul 15, 2015

Yeah i know. that's what i meant though, more of a hassle for n3ds hence the need for a hardmod.

gudenau · Jul 15, 2015

Neat, now people can "port" new titles.

Sure, use cia (updateCDN) files to update it to 9.6.0.
