Homebrew Official [Release] GodMode9 - All Access File Browser for the 3DS

[Ryccardo]

can friendsave.bin and seedsave.bin be dumped?

They're just convenient shortcuts to encrypted nand saves:

https://github.com/d0k3/Decrypt9WIP...60ce63e1c0cf66/source/decryptor/nandfat.c#L56

Is it possible to use GodMode9 to get my original "secret sector" from my emunand?

It should be under "emunand virtual"/sector0x96.bin, but I don't know if it's encrypted or decrypted, nor if it can be safely copied this way...
(Upgrading to sighax with SafeB9SInstaller will flash a genuine N3DS secret_sector; on O3DS it doesn't matter anyway as long as you're not running a N3DS kernel (which is how A9LH works)

can I use this to edit game soundtracks with my own music?

Romfs editing isn't supported (it's an archive, itself a layer inside the NCCH, with multi-level hashing; it would be too slow to be practical on a 3DS)

Consider using Luma's game patching (layeredfs) if you want an incremental patch, or extracting and recompressing a cia if you want to really integrate your mods in the game

This embeds a minimum size backup, which will include all files required to restore your NAND (to factory state). It's somewhat of a last resort thingy, if all else fails.

Thanks. I get it.

You could have looked in the readme. That option only turns up if you have enough free space, and that can be different from console to console (even among same type).

I did look for the answer in the readme. Enough free space where though, I'm assuming SD card space as the readme says "The bonus drive can be setup via the HOME menu on 3DS consoles that provide the space for it.". If that's the case I have plenty of space. 59.6GB as shown in the pictures of each console.



Edit: Oh I see, you mean Home Menu of GodMode9. That's where I was confused. But I'd still like to know where I'd need the free space as my SD card has plenty on both consoles and the option only pops up on one.

Hi, @d0k3. Sorry for bothering you.
I'm probably doing something wrong, but GodMode9 doesn't seem to be detecting BOSS files.
The files I'm trying to decrypt do have a valid BOSS header, but, when I press A on them, the only options I see are "Show in Hexeditor", "Calculate SHA-256" and "Copy to 0:/gm9out".
I have tried both the latest stable and the latest nightly of GodMode9, if that matters.
Decrypt9 still does decrypt those files fine, but I would rather ditch it, to be honest.
Is there something that I'm missing?

EDIT: Funny thing, out of four files it recognized as BOSS only the smallest one (which is few kB in size, three others are more than 10 MB each).

You need that space on your NAND, of course.

Can you maybe upload these files somewhere and send me a pm?

OK, in that case the console that does not display the option to setup bonus drive has more space on the NAND than the one that displays the option.

I don't mean to sound like I'm bugging you, just thought maybe something was up. How much free space is needed?
<--- option present
<--- option not present

Edit: Is that used space or free space that is displayed under "Directory info"?

You got that wrong. This is about the size of your NAND chip. Take a look at S:/nand.bin, that file has the same size as your NAND chip, and for many consoles there is a large portion of unused memory after the end of the actual data.

Feature request: decrypt dev cias (especially the sd updater pack cias for SNAKE).

ctrtool can do that now in the latest commits, use -d to use dev keys

OK, thank you for explaining that further. Much appreciated.

That explains why my 2DS which shows the option, it has a larger NAND chip. Thanks again for taking the time to respond.

That should already work, actually. Can you mount these CIAs?

They mount fine, but the ncch content fails to decrypt.

SD_SystemUpdater_SNAKE-0_25_4-US.cia

Did you provide the dev keys via aeskeydb.bin or slot0x??key?.bin? Also tried it on boot9strap?

I tried to add the needed keys manually and no luck. Yes, I'm using b9s as well.

I'm trying to figure out a way to backup and restore the PTM savegame, which as far as I can figure out (https://www.3dbrew.org/wiki/PTM_Savegame or http://webcache.googleusercontent.com/search?q=cache:https://www.3dbrew.org/wiki/PTM_Savegame ) includes the per-day play log and pedometer log (which would be shown in the top part of Activity Log).

I can't figure out how to do it.

According to https://www.3dbrew.org/wiki/System_SaveData or http://webcache.googleusercontent.com/search?q=cache:https://www.3dbrew.org/wiki/System_SaveData , PTM is 0x10022 and the savedata would be in data/ID0/sysdata/00010022/00000000.

Using GodMode9 I went to "1: SYSNAND CTRNAND"/data/(ID0)/sysdata/00010022/00000000", which seems to be the right place. However, this is not a directory containing files Pedometer.dat and PlayHistory.dat, but a single file named "00000000".

Trying to copy the 00000000 directly to the other console, copying from SD, and pasting it into the same place I got it from didn't work. It did erase the previous data, so at least I know this is the right place. I presume I have to decrypt it using decrypt9 and reencrypt it on another machine, or at least extract and inject the Pedometer.dat and PlayHistory.dat. However, I don't know how to do that. Can someone help me with this?

Edit: I found https://www.3dbrew.org/wiki/Savegames (or http://webcache.googleusercontent.com/search?q=cache:https://www.3dbrew.org/wiki/Savegames ) but that's no use to me as is. Is there some tool that can do it?

Did you ever figure this out?

Missed that. @Jiro2, what you have to do after copying that data is, fix the CMAC (the option is in the A button menu) for the new system. @Quantumcat maybe you want to try this, too.

I tried to add the needed keys manually and no luck. Yes, I'm using b9s as well.

I may have an idea what goes wrong there... are you trying to decrypt dev content on a retail unit? Also, did you already try this on A9LH? And, did it work then?

May make sense to open an issue on GitHub for it, it's a bug if it doesn't work on devkits.

I find this about 1,000 times less intuitive to use than Decrypt9 and FBI, in terms of NAND backup/restore and file manipulation within the CTRNAND. Sometimes, an "all-in-one" tool isn't always the best approach.

Maybe grab the code and make lots of little tools, one for each job, with a menu interface that you like :-)
I would probably try this if I had any confidence in my skills and I wouldn't probably be spending a week trying to compile it then giving up

 

[hobbledehoy899]

Hmmm, there's no boot9strap-compatible builds of SafeMode9... (Probably because you don't need condoms with a strap-on! )

It's the same situation with Mednafen.

There are, look on my hourlies page (in my signature below).

And, well. I'm getting tired of "D9 / HG9 is better than GM9" posts. From an implementation standpoint they are clearly not. From a functionality standpoint, neither. The "more intuitive" argument is basically just "I did it that way forever, and I'm too lazy to start doing it another way". The NAND backup / restore may even require *LESS* keypresses in GM9 than it did in D9/HG9.

And, again, I'm not stopping anyone from holding onto D9/HG9, so I really don't get what all these complaints are about. I even did a new boot9strap compatibility release for both a few days ago. It's just that D9 and HG9 won't get any more new features or improvements (from my side, everyone is free to continue development), cause I really feel that at this point this is no more than putting lipstick on a pig.
