Is it true that slot0x25KeyX.bin isn't needed on 9.2 sysnand consoles? I didn't use to need it before, but received a message about it when decrypting a newer game.

yes, it's true

help?

strange
did you installed the setup first?
Check your program files folder, and if you'r on 32b or 64, check both program files folder

- Added a Full VirusTotal Scans : http://pastebin.com/AzCq4QGD
- FIXED the Pokemon Patch Injection. The Updated Tutorial will follow.
- Fixed a typo in the cxi script extraction.
- HackingToolkit3DS is always more faster to load (The main file is just 100kb).
- New Links

Hey, when I launch my newly randomized Pokemon Alpha Sapphire, I get an error

All 5.0 English Users : Please uninstall your 5.0, redownload it again, and reinstall it.
Because I incuded a bad MakeRom (not a good version) which will be used in the pokemon patch injection
French users don't need to do it, the 5.0 french pack is fine

--------------------- MERGED ---------------------------

I didn't change the version number just for 1 file, so it's always 5.0

Link and Zelda are making Linkle ?

@Asia81, is there a way to build a .cia directly from the HANS files of a game?

I wanted to build a CIA for the Rutile Ruby rom hack. Or should I start the process with a .3ds of Omega Ruby?

edit

Nevermind, I decrypted the .3ds and got it working. Thanks for the tutorial!

Hello, Can I use this tutorial to repack a Cubic Ninja ROM, changing the update data to include a 9.2 firmware (possibly both for O3DS and N3DS) and load it via Sky3DS? I am helping some friends hack their 3DS's this weekend and some have very outdate firms, so if this could help me get them to 9.2 easier it would be great.

So I've used the hacking tool to extract the Romfs of Fire Emblem Fates, and I've used other programs like FEATS to extract the .lz files, but most of the files don't leave folders, but more binaries. I'm trying to see if it's possible to edit enemy skill data for a hack I have in mind, but I've kind of hit a wall on what to do next. Is there anything in the hacking tool that I can use to decrypt the binaries? Or do I need to use a different tool. Hell, is it even possible?

 

[Asia81]

My code is the worst crap ever...
But at least, it will "I hope" work, and so open source on Github.

But since I'm a very BIG noob in C#, I don't know how to implement it directly in the tool itself, instead opening a CMD...

 

[Asia81]

Spoiler

If someone have a good feeling with C#, please send me a PM...
I really need help :/

Does this work for New Nintendo 3DS?

So, decrypting HAS to be done on a 3DS? That's disappointing. If the keys are known, why is there no PC application that decrypts?

 

[TheGreek Boy]

how can i change the name/publisher/icon/banner of the game?

 

[Halvorsen]

I can't extract anything. No matter what download I use, or what CIA/CXI, toolkit says it cannot find the path specified.

Has anyone looked at getting the rebuilt roms to run in Citra? I've been trying for like 2 days now! 3DS Builder breaks encryption for me.

Managed using 3dstools and makerom.

 

[Mike_77712]

So confused..how can i dump my .3ds rom? i put it on my sd card and braindump says it cant find any titles

Ok, guys, good news, I managed to:
- Modify and rebuild any CIA updates (But you need to use the clean update as a base, you can't create the update from nothing),
- Rebuild a custom .3ds with all extra files (manual, updates, dlplay, etc.). These extra can of course be edited, like a custom manual.

I still need to try to convert it directly to .cia without .3ds first, but I have no luck for know.

Anyways, you can always convert it to CIA using 3DS Simple CIA Converter (3DSSCIAC, shorter).

But in this case, 2 things:
- Updates partition 6 and 7 will be removed (due to 3DSSCIAC).
- You need to encrypt the custom/created .3ds with Decrypt9 (using NCCH/NCSD Encryptor), then generate the ncchinfo.bin using 3DSSCIAC, then generate xorpads with Decrypt9, then convert it to CIA like usually (using generated xorpads + the new encrypted .3ds (our custom .3ds)).

I will update the tutorial asap
