Perhaps he's on emuNAND?

My sysnand's my main nand as I've switched my emunand partitions over to it now and it's on 10.6.

Time for a new release: The 'a9lh' maintenance release with one big new/fixed feature (I mean Secure4 crypto, if that's not clear).

This is new:

This is now a9lh compatible (although a lot of stuff will not work - known issue)
Dumping seedsave.bin & updating seeddb from SysNAND (this is a thing with a9lh now)
Enabled Secure3 NCCH crypto / padgen on O3DS (need slot0x18KeyX.bin)
Enabled Secure4 NCCH crypto / padgen on O3DS / N3DS (need slot0x1BKeyX.bin)
Added a selftest feature

This is how the selftest feature works: (1) create the reference data on a known working entrypoint (= not a9lh!), (2) run the selftest on the entrypoint you want to test.

Now we can finally get behind on what cause some stuff on a9lh not to work. @Shadowtrance, and @Svaethier I'm burning to know your selftest result, and everyone elses (on a9lh).

When you mention A9LH compatible (assuming just dumping emu/sys works as always) are you meaning cold booting straight into A9LH binary? Or do you mean booting a 9.0 nand and launching 3DSX via HBL?

The former, the last one should have always worked.

That's what I figured.
On the phone =( I assume we can use the decrypt9wip.bin as our A9LH payload?

They should not be too hard to find. Google is your friend, or maybe some other forum.

So why did @Toiry921 only get 1 fail and i got 4 with my test? N3ds thing?

Because he ran it from HBL... And the one fail is a false alert.

I did the same, ran from hbl first for reference then ran the "test" from a9lh.

Did you recreate the selftest reference when trying it on A9LH

I didn't, no.

I'm trying to decrypt my VC SNES mario world eur .cia (build with groovycia) but...
decrypt9log: Code / Crypto: KTR-N-UAEE / Secure4 Seed Loading slot0x01KeyX.bin: not found Failed!

Hyura · Mar 4, 2016

I'm feeling extremely dumb, but I have to ask it.

Is it normal to get different md5 numbers from my NAND backup when I use Decrypt9 after rebooting my 3DS?

ItsMetaKnight · Mar 4, 2016

@d0k3 Any chance you could add boss file decryption in the future?

Keyslot 0x38 is involved in decrypting them. I'm working on a new tool and until now it has been a pain to get decrypted files... >_<
Attached is a sample boss file for testing.
