3DS TO CIA 2.07 by Katsu

What is 3DS to CIA?

Its a tool designed to convert ROM dumps into installable CIA Files
with Features for Modifiers who want to Translate or edit Content.

Required:

A 3DS capeable to generate XORPADS for legit 3DS to CIA
Python 2.7
(Add Path to Windows Enviroments!)
Example: c:\windows\system32;c:\python27

How to use:

.3ds to cia:

1. Create your xorpads and put all files into 3ds to cia dir next to 'Make' batch
2. *Drag n drop .3ds / .3dz on 'Make' batch
3. Choose your Options and start

Decrypt selfmade cia: - no legit cia -

1. Drag and drop your cia on 'Make' batch

Extract decrypted .3ds: - no legit/rebuilded/regenerated 3ds -

1. Rename your .3ds to <filename_modified.3ds>
2. Drag and drop your .3ds on 'Make' batch

Quick rebuild from files inside folder:

All files need to be inside the same Folder
(romfs.bin/banner.bin/code.bin/exheader.bin/icon.bin/logo.bin/.rsf***)

1. Edit your .rsf to work as .3ds NOT .cia!
2. Drag and drop your Folder on 'Make' batch

***As for rebuilding .3ds, a working file depends on your Skill to modify your .rsf

Mostly there is not much to change, make sure to change at least:

Title / CompanyCode / ProductCode / UniqueId / MediaSize
MediaType / CardDevice / ExtSaveDataId / SaveDataSize
and if needed: JumpId

You can take my "sample-rsf-reb.txt" and fill in the needed Details,
from exheader.txt / info.txt and "rom_tool -i <gamename.3ds>".

Features:

7.x Support
Region Free fix
Offers injecting original EXHEADER
Offers spoofing Firmware to 4.x
Offers using your own .rsf (no exinjector)
Download Play Support
Includes Manual when detected
Auto RSF - big thx @ Vappy
Decrypts manual created cia
Rebuild .3DS (Target -G)
Allows to de/re crypt romfs for editing purpose
Quick rebuild .3DS per Folder drag n drop
Quick rebuild .cia per Folder drag n drop (requires .3ds/.cci)
Supports decrypted .3ds from rxTools

GREEN - ALL OK / RED - SOMETHING WENT WRONG

Included in Package:

RomFS Builder - Thx @ SciresM
ExInjector - Thx @ piratesephiroth
3DSExplorer
Notepad++
ctrKeyGen
Launcher.dat
slot0x25KeyX (you need to insert the key - google it!)

What is new in 2.04?

Added Decrypt9 Bootstap Version for Ninjhax (new3DS .3dsx)
Added Option 8 "check .rsf for auto generation" (manual check before building cia if rsf fails)
Speedup when DLP and or Manual is included
Minor changes and Bugfixes

What is new in 2.05?

Fixed Bug for .rsf generation
Added libeay32.dll

What is new in 2.06?

Rebuilding from _modified.3ds / .cia got completly rewritten
Changed main Menu to allow more options
Rebuild .3ds will now includes original Exheader to keep compatibility to updates/dlc
Excract ROMFS is now aviable for all main functions
Added option to keep decrypted files
Original file is now in "original" folder after using 3ds_to_cia
Some cleanup from old code / minor bugfixes

What is new in 2.07?

Fixed a small bug to keep original
Speeded up cia repack

feel free to do so, as long you share it to everyone

Will this work with roms decrypted using rxTools? Unlike the xorpad method, the roms get decrypted directly with no xorpads, so the file I would feed this thing has no encryption and wouldn't need xorpads. The only issue is if the batch scripts in this can account for that.

I've updated my Batch to Support rxTools decrypted .3ds directly to rebuild either, .3ds or .cia.

ctrtool.exe has stopped working.
I compiled ctrtool from the source.
And now it's working

Misread it as CIA to 3DS... ah...
Still, this is nice

Doesn't make rom have a command to convert CIA to 3DS? Just use that. ("makerom -ciatocci nameofrom.cia" to be specific) Just use that if you want to convert CIAs to 3DS. May not work if the CIA is encrypted with production keys. Zero key stuff like CIAs converted from 3DS or repacked ones should allow you to convert to 3DS.

Just tried to use a decrypted 3DS game. Your batch file still stops at the missing xorpads error.

EDIT: Seems you might not have uploaded the new version for this yet....

 

[liomajor]

I did, have you renamed the file as mentioned in 1st post?

 

[Apache Thunder]

Ahh now it works. Mine has "_decrypted" in the file name. But didn't know filename mattered. I changed it to _modified in the filename and it seems to be working now.

Is this the same Katsu from wololo.net? (Vita scene dev)

Hello, thanks for this usefull tool, I tried to convert MK7 and Sm4sh to cia, from my own dumps, I've dumped many times these roms, thinking the problem could be my dumps, but without any succes, I've converted PKMN XYORAS already and them have converted, installed and played perfect. When install MK7 and start, it stay in a 3DS Logo loop... and with Sm4sh the screen shut off and on, like normal, but then it stays there, in black screen, I have to do a hard-reset to shut down my 2DS, I left every option normal :/ any idea? Thanks!

hmm...can someone explain what is meant by "A 3DS capeable to generate XORPADS" ?

* thanks in advance *

also, just to get my facts straight, CIA stands for CTR Importable Archive ?

To generate those XORPads you need a 3DS with the launcher.dat(to generate XORPaads not the Gateway), slot0x25keyx.bin, and ncchinfo.bin(of the game) on the big SD card, this means you need a 3DS capable to run launcher.dat, just search which one work for you depending on you Firmware.
I think there is a way to create CIA without XORPads with rxTools-something, I haven't tried this.

someone have a guide to create RSF? I can't find :/

This is for 3DS to CIA conversion with dumped .3ds for decryption. You can't do this without a 3DS between 4.1 - 9.2 with the given Tools.

Simply take a look inside my sig. For rxTools decrypted .3ds, you can take my "sample-rsf-reb.txt"
and fill in the needed Details from created exheader.txt/info.txt and "rom_tool -i <gamename.3ds>".

Thanks for the explanation, and it appears my 3DS is currently on "Ver. 9.2.0-20U"

* not sure if that is in the firmware range of using this *

Hmm, so I would also need a "Gateway" to install the CIA file ?

Yeah, Gateway.
Or downgrade to 4.5 and use a Custom firmware

 

[breaktemp]

Asia81

Okay, and good looking out !!

* now to look into getting a Gateway, or finding someone close by with one *

So once a CIA is installed on the system, using Gateway, would one need the Gateway to run the CIA ?

 

[Asia81]

Yes, if you install a CIA using gateway, you will always need gateway.
Gateway is needed to enter in Emunand, and Emunand run CIA installed

Just saw this update today, I've been using your 2.00 converter for quite awhile now, and its the best one I've come across!

"A 3DS capeable to generate XORPADS for legit 3DS to CIA"

any way there will ever be a tool created that incorporates some citra source to make a 100% automated 100% pc based solution?
can xorpads be even be generated with citra?

Citra doesnt emulate the aes engine and probably never will.

Can anyone confirm v2.02 woks with rxTools after adding '_modified' to the filename?

Ahh now it works. Mine has "_decrypted" in the file name. But didn't know filename mattered. I changed it to _modified in the filename and it seems to be working now.

 

[powersaver]

Anyone know how to convert 'Donkey Kong Country Returns 3D' (CTR-AYTE)?
