ROM Hack [Tutorial] How to Decrypt, Extract & Rebuild 3DS|CIA|CXI Files

[medoli900]

Wait- how do I update Decrypt9?

Download it here: https://github.com/d0k3/Decrypt9WIP/releases
Then depending of your setup, the installation will change.

"Decrypt9 can be built to run from a number of entry points, descriptions are below. Note that you need to be on or below 3DS firmware version v9.2 for any of these to work.

• A9LH & Brahma: Copy Decrypt9.bin to somewhere on your SD card and run it via either Brahma or arm9loaderhax. Brahma derivatives / loaders (such as BrahmaLoader, BootCTR and CTR Boot Manager) and A9LH chainloaders (such as Luma3DS and BootCTR9) will work with this as well. Build this with make a9lh.
• Homebrew Launcher: Copy Decrypt9.3dsx & Decrypt9.smdh into /3DS/Decrypt9 on your SD card. Run this via Smealums Homebrew Launcher, Mashers Grid Launcher or any other compatible software. Build this with make brahma.
• CakeHax Browser: Copy Decrypt9.dat to the root of your SD card. For MSET also copy Decrypt9.nds to your SD card. You can then run it via http://dukesrg.github.io/?Decrypt9.dat from your 3DS browser. Build this via make cakehax.
• CakeHax MSET: Copy Decrypt9.dat to the root of your SD card and Decrypt9.nds to anywhere on the SD card. You can then run it either via MSET and Decrypt9.nds. Build this via make cakerop.
• Gateway Browser Exploit: Copy Launcher.dat to your SD card root and run this via http://go.gateway-3ds.com/ from your 3DS browser. Build this with make gateway. Please note: this entrypoint is deprecated. While it may still work at the present time with little to no problems, bugs will no more be fixed and it may be completely removed at a later time. Use CakeHax instead."

It is a little outdated, in the sense that it will works on latest Sysnand firmware if you already have A9LH.

ok so i cant seem to get any files from the 1.1.4 Update at all
all i get are a crapton of .cia files that i cant do anything with
i got the data from the Original game tho and all files seem to be in order
i just cant get the Update data...
what should i do???

 

[Fer123]

I have a decrypted fire emblem:awakening (.3ds), and I have a "all-dlc.cia". I don't think the .cia is decrypted or anything, it was just a dump from someone else's 3DS. I'm trying to combine the .3ds with the dlc .cia so that I can play on Citra with full dlc. Is this currently possible with this method? (Not sure if .cia needs to be decrypted or something)

Sadly, I don't have access to a 3DS anymore, it was stolen.

 

[Asia81]

no

 

[Fer123]

no

What would I need to do then? Find a decrypted .cia dlc as well?

 

[Asia81]

It's simply not possible to merge a DLC into a CIA/3DS

When i try to extract my rf4 undub cia i get no files at all, can anyone help me?
is that because the game is already a hack or something like that?

EDIT:i could fix it,it was because im using a 32bit windows
EDIT2: now when i try to rebuild my cia file i dont get my file any help?
EDIT3: i tried rebuilding it as a 3ds file but i get a 0kb file

 

[Blep]

So I'm on Sys 11.3.0.. do I still need to downgrade?

 

[Asia81]

Could anyone, with a 32 (and NO 64) bits windows, pm me?
Thanks!

Can someone tell me why I keep getting this error:

I'm not getting any files after this either.

It means your CIA is already decrypted.
It doesn't write a new file. It just works on the file you give it.

Oh okay but when I tried to extract it's romfs with this program by asia81 it didn't give me any files either.

It does that when the CIA isn't decrypted. That's weird.
What version of Decrypt9 are you using? The latest version is 20170225.
I think GodMode9 is replacing it. Try that instead and see if that works. https://github.com/d0k3/GodMode9/releases
Have you tried other files and do they work with Asia81's tools? You have to install it first.

Godmode9 says the exact same. That it is not encrypted.

Make sure you have Asia81's tool installed. You have to run the setup.exe. It'll make a folder in your default Program Files (x86) Folder called HackingToolkit3DS. It should make 20+ files in that folder. You can run the program after that from wherever you were running it and it should work.

I retried the process and it just worked. Thanks for the help I appreciate it.

Is your OS a 32b or 64b ?

Before report an issue, be sure:

• Your .3DS/CIA/CXI files are fully decrypted
• Your .3DS/CIA/CXI files doesn't have any space or special caracter in their names (such as é or à)
• To don't write the extension when asking for extract your game. Want extract "Game.cia"? Just write "Game".
• To have installed the Setup package for your langage.

EDIT : Oops, too late.
Anyways, this is what happen when peoples don't read what is needed...
