For r_NAME.bin, a_NAME.bin and select_NAME.bin you need to press L+R, L+A and L+SELECTon boot respectively.

L is reserved for "Autoboot SysNAND" option
R is reserved for "SysNAND is updated" option
B is reserved for "Use second EmuNAND as default" option
Select is reserved for loading the options menu

Whats A reserved for?

This isn't really the best place to ask. Buy anyway, the A button will force Luma3ds to boot into the default location during MCU reboots.

So if I normally autoboot emunand and I press a reboot button on sysnand while holding A, I will boot into emunand instead of returning to sysnand.

Please understand.

Guess this is why Decrypt9 did not load when i renamed it a_D9.bin. I see now, so the best way to keep it is what i have it as, or should I rename it r_D9.bin? Which would be easier?

Personally I use D-pad down.
Down_D9.bin

Do you know why I can't decrypt/encrypt the smash controller app?
D9 say it's not a CIA file, but it is definitely a CIA fle because I can install it just fine.

Opening /D9Game ...
Processing CIA "OtherSmashControllerEUR.cia"
Probably not a CIA file
Failed!
CIA Decryptor (deep): failed!

Press B to return, START to reboot.

That's an interesting problem. Have you tried making backups of that file and renaming them to .3ds or .cxi etc?

Asia81 · Jun 18, 2016

why rename to 3ds / cxi since it's a CIA ?

Idk. I was just wondering cause it is interesting.

D9 does not actually check the extension, so it wouldn't do anything.

Alright, had a look. Even if it is installable, that file is corrupt. It has a wrong content size in it's header. Maybe rebuild this with makerom?

Also, want to help me test something? This D9 test build has a cart dumper (with various options) included:

dumped a game (Pokémon Rumble Blast, contains 2.1.0U) with Uncart and Decrypt9;

full dump changed some things at offset 0x1000, which seems to have some extra data and a clone of the first NCCH header minus signature. with the dump from Decrypt9 it's almost entirely "FF". I don't know if this was supposed to happen. rest is fine though.
https://www.3dbrew.org/wiki/NCSD#Card_Info_Header if it's useful?

decrypt dump apparently did not work, despite verifying being OK and I can see the decrypted contents in a hex editor....?

I'm getting the same results with Freaky Forms Deluxe.

so I noticed that with Pokémon Rumble Blast, it didn't decrypt the update partition. so I tried Mario Kart 7, and it "failed" also.

extracting it on a computer tells me only the first partition (game/cxi) got decrypted. manual/dlp child/update partition are still encrypted.

@d0k3
I compiled your latest commit 02572f1. Make compiled fine, but Make Release produced libkhax errors.
How can I fix that?

Thanx

Yup, I messed decryption up. It is fixed with the latest commit, though.

That's because libctru introduced incompatibility again... -_-. I'll fix it, but will take some time, and will break earlier libctru compatibility.

For now, you could use an older libctru.

... Or get the compiled build from my hourlies page.

Unrelated to anything: Is there a meaning to your name? Is it pronounced Dough-key?

now it's failing to read the NCSD header. I just built the "gcdumper" branch and tried it out.

Code:

Detetcted cartridge id 9000FAC2...
Error reading cart NCSD header
Dump & Decrypt Cart (slim): failed!

Press B to return, START to reboot.

Detetcted cartridge id 9000FAC2...
Error reading cart NCSD header
Dump & Decrypt Cart (slim): failed!

Press B to return, START to reboot.

Detetcted cartridge id 9000F8C2...
Error reading cart NCSD header
Dump Cart (full): failed!

Press B to return, START to reboot.

oh yeah, it doesn't seem to be putting them in "D9Game" even though it tries to. it's always "Decrypt9".

Possible to dump the header, and just the header, without dump the full cardrige then use gateway rom patcher for extract it?

Nice idea. Maybe you could start it. Cut out all the code that doesn't dump the header. Then edit the name from Uncart to Decapitator.
