Converting .3DS/3DZ to .CIA Pictorial

Hopefully noob friendly!​

UPDATED! V5.1.4b @ UTC+8 2.45am 24-Nov-14:

Updated calling routine:​
Most questions all in front, so that users can doze off after​
Included the most recent exinjector & rsfgen.py​
Testing 32-bit compatibility​
Note: Haven't updated tutorial, but the prompts should be fool proof.​

T2 - Basics

What are .cia files?​
Basically a somewhat stripped down decrypted version of .3DS files.​
You can't just rename .3DS > .CIA, you have to carry out a set of slightly complicated steps,​
which I have tried to get it dummified.​
Make sure you follow the steps concisely.​

Now, purpose of this tutorial is to guide users to convert 3DS games (not warez, not dev apps) to .CIA files for installation.​
Does not matter whether .3DS or .3DZ, and scene roms won't need to add 'header' to go online (GW users should know what's I'm talking about)​


T3 - Requirements

First off, these are the requirements:​
  1. Using a 3DS that is FW 4.1-4.5 (also known as FW 4.X)
    I recommend that these users get a Gateway 3DS.
    .
  2. A DS flashcart that works on your 3DS, for loading DS profile exploit
    Supercard DStwo or GW blue card (r4i) works.
    Gateway loader works fine. (cannot link you the link)
    .
  3. Install 2.7 Python. You can find it will a quick Google search.
    Or just download the one for your computer from here:
    https://www.python.org/download/releases/2.7/
    .
    ..
  4. This package.
    Paste it on your desktop, in a folder named "CIA"
    http://filetrip.net/3ds-downloads/utilities/download-quenopack-3ds-to-cia-5-1-4b-f33005.html

    Please the files in the folders they were in.
    The program reads the stuff based on the location!
    I will not provide the 7.x key. To find it, simply search the guy who leaked it. ><
    .
  5. A game backup (rom)
    .
  6. Patience, and not fearful of looking at folders with multiple items!
Okay, let's get started.



T4 - The Main Tutorial

Video Version:It's based on older revisions, but still counts.
Thanks to TeamNinja for uploading, and DrWhoJan who brought it to our attention!

Step 0: Tools usage and folder placement
Okay before we begin,
a short reminder: strictly please use only the tools I provided for this tutorial:
http://filetrip.net/3ds-downloads/utilities/download-quenopack-3ds-to-cia-5-1-4b-f33005.html

The folder layout and location of the files are to be the same,
as I have optimized the calling procedure of the .bats (the programs).

Unless you have a working understanding of reading those and modifying them to your liking,
I suggest you follow as I have provided :)

As an addition, follow the images to unblock the .rar, before unzipping:
2CnQzzS.jpg

Step 1: Decrypting the Rom
1a. Getting ncchinfo.bin
Go to CIA\Step 1
Paste your rom in this folder.
Rename it to "rom.3ds"

PL7i0Of.jpg


Drag the rom.3ds onto ctrKeyGen
A file called ncchinfo.bin will be in your directory.

PP2d2Vb.jpg


Now, go to CIA\For 3DS SD Card
Copy the launcher you use over to your 3DS SD card.
I will not provide slot0x25KeyX.bin, so find it yourself.
When you the value, HXD into a blank file, and save as slot0x25KeyX.bin
S5pjz4H.jpg


Also copy and paste ncchinfo.bin into the root of the 3DS SD card.

pxb4yYC.jpg


Now insert SD card back into your 3DS

1b. Getting xorpads
Go to your 3DS.
Run System Settings > Other Settings > Profile > Nintendo DS Profile
n0AavEQ.jpg

5Rc1S0H.jpg

NwOqJMT.jpg

2IjMk6y.jpg

The program will load and run.
Allow it to run until it tells you, that you can turn off your 3DS.

yLff9EH.jpg

YlpCabp.jpg


Once done, insert your SD card back on your computer.
Copy only these xorpads to this directory:
CIA\Step 2
Not every rom provides exefs_7x.xorpad. If you do see it, you must copy it!
Only copy manual.romfs.xorpad if you want to have a user manual option on home screen.

Fo9jCzq.jpg

If you game has Download Play support, and you want it,
copy this too:
5KvoodX.jpg

Step 2: Decrypting + Compiling the .cia!
Move rom.3DS to CIA\Step 2

XipcAm6.jpg


Drag and drop or Double click on 'decrypt and make.bat'

tLI1w0u.jpg


Hit enter, and it will run.
The latest update has all the questions at the start of the process,
so one may mostly doze off and wait after doing so.
The image that says it all!
VZ2EdYp.jpg


When you see this, you are at the end of the program!
If you see install.cia, it means you were successful!

WCurpGN.jpg

"But Queno138, I want to repack another rom, must I unpack again?"
No!
This feature allows you to repack, as long as you have the items there.
It's been around since, 2.0? I just never properly documented it.

After this image, go up to (continue)

Installation Success!

T5 - Reference Codes (and how to report errors)


Reference codes has appeared in the batch program, for ease of referencing.

Genuine Errors
Reference code 1: Required .bins not located.
4KYeogO.jpg

If the required .bins for the operation is not found,
it means that either you deleted it, or it could not be extracted, due to decryption error.

Associated with (and fix):
1. Invalid slot0x25KeyX.bin for FW 7x games (refer to guide on how to acquire it correctly)
2. Files have been moved (kindly keep them in the same place as guide dictates)
3. Decryption error. (Delete everything and try again.)
4. Mismatched tools (Ensure you are using the tools provided)


Reference code 2: rom.3ds not located.
Uxw5lzg.jpg

Decryption cannot be done without the exact file, "rom.3ds"

Associated with (and fix):
1. rom name is not rom.3ds (Kindly rename the rom to rom.3ds)
2. rom not in folder (kindly place rom.3ds in Step 2)


Reference code 3: xorpad not located.
FR5pUbq.jpg

Xorpads are required for decryption

Associated with (and fix):
1. xorpad not named as per guide (simple, eg: 01.exefs_norm.xorpad)
2. xorpad not in directory (don't forget to transfer over the xorpad from 3DS SD card)


Reference code 4: Tools folder not found
R9j5cda.jpg

Tools are required for the operation.

Associated with (and fix):
1. Tools folder has been renamed. (It needs to be named "tools")
2. Tools folder has been moved. (Move it back to the original directory)
3. Tools folder lost. (Redownload and extract the whole package)


Reference code 5: Folders located before decryption
tWxh7lf.jpg

This message only pops up when you have chosen to decrypt a rom.

Associated with:
1. Exefs, Encrypted_bin, decrypted, xorpad folder exists. (delete them before decrypting new rom)
2. Selected choice by accident. (ignore, proceed to pack rom.)

Faux errors:
Some of the text displayed tends to scare users.
If you get any one of these, please don't report, as it's not an error.

Reference code not shown/code persists:
If code persists, or error with no code:
Do us a favor and save each other some time.
Before showing errors,
ensure that:
1. you downloaded the lastest package.
2. followed the tutorial to the latter
3. did not use express
If error still occurs:
1. What Game you are using
2. Inform me if you are using CFW or GW
3. Tell me what error you get in game (or if you don't reach there)
4. screenshot \exefs, \decrypted, \xorpads, \step 2
5. show me the error page on the normal bat

this way, easier for me to identify the error.


T6 - [The not so] Frequently Asked Questions (FAQ)


What must I not do?
Don't go into sysnand and check data management. (content will be deleted)
Don't forget to back up data when necessary (to prevent losing saves)
Don't forget to read T5 of my guide regarding errors. (to not plague this thread)
Don't format 3DS for no reason (I mean, imagine one day you need to upgrade, and can't connect to NNID or something)
Don't update firmware in CFW (cause it stops working)



How to install .cia files
What, you're here without knowing!?
Basically, get Devmenu or bigbluemenu (can't tell you where)​



Will I be able to delete them afterwards?
Devmenu and BBM has options for deleting them.​
Just don't delete your updates or important warez by mistake.​
Check the ID against http://3ds.essh.co/



Does this require FW 4.5 like other exploits
.....​
You think?​
</sarcasm> YES



Does this work with trimmed roms?
YES! (link)​



Does this work with FW 7.X games?
GW = YES!
CFW = NO.
And before you ask, if there were any workarounds​
(well, besides obviously getting a GW that is so worth it now),​
I'll be happy to share.​



Does your tutorial contain "region free and firmware spoofing"?
YES!


Does the package support download play?
YES!



Does this work with .3DZ?
YES!
After all, it's just a file extension. doesn't affect conversion.​



Does your tutorial contain "user manuals"
YES!



I have an existing save on Gateway. Why is it not on the .cia game?
Imagine the .cia game being like an eshop game.​
Every game comes with a new save.​



Are saves brought forward?
NO.
Because that's not how the mechanics of conversion works.​
Gateway makes the redcard 'find and see' the saves, not the homepage apps.​



What about nand saving/card2?
NO.
But ONLY for card2, you can use savefiler or save data transfer tool.​
If you were already playing your roms as a card2, go ahead and transfer :)



Why can't I modify to card2 then transfer?
By making it card2, you broke the header,​
which the 3DS will check if the save is corrupt before transfer.​
Based on the chain of events mentioned, it is considered corrupted.​



Can user manuals be repacked together?
YES!
Take note that if using different region game,​
enable region free.​



Does this work with VC roms?
NO (link) or YES? (link)​
Try it yourself!​



Does this conversion method work with Dev apps (devmenu and SDK stuff)
NO!
However, link to show you how to get them converted: (link)​



Do I need .rsf files?
Up to you. The batch program will generate one for you,​
but if you follow the prompt, you can insert your own.​
Not all work at the moment.​



Can I load games above 4.5 on CFW?
From what I know, some games require firmware spoofing​
and the FW6/7 games is a big NO



Where can I find slot0x25KeyX.bin/7.X keys?
Can't tell you where. But I know who has it (the guy you leaked it, duh)​
get it, type it in hex using HXD, save as slot0x25KeyX.bin​
Paste it into your SD card.​



Why do I see no errors but there is no .cia?
Most likely you are using express. IF you are noob, just don't.​
Chances are it's decryption or your key 7 is wrong.​
Go to section T5, it'll teach you something.​



It says not enough memory, why? I have x GB ram.
Well, your computer probably already runs a lot of processes,​
and packing the rom can take up to 2-3x it's original size.​

Don't tell me you got 16GB ram.​
Just go o into safe mode, and launch the .bat there.​
As long as the folders are still there,​
you can choose to continue with repacking, without re-depacking.​
If it still doesn't work,​
rename _makerom.exe to makerom.exe and try again.​
I've already added a new makerom to circumnavigate that,​
but I still recommend keeping your processes low.​



Help, can't drag and drop on python
try either option:​
put this into a .bat
Code:
c:\Python27\python.exe" ctrKeyGen.py %1
then drag and drop the rom.3ds onto the .bat

Or

Code:
regedit
 
[HKEY_CLASSES_ROOT\Python.File\shellex\DropHandler]@="{60254CA5-953B-11CF-8C96-00AA00B8708C}"
 
[HKEY_CLASSES_ROOT\Python.NoConFile\shellex\DropHandler]@="{60254CA5-953B-11CF-8C96-00AA00B8708C}"
 
[HKEY_CLASSES_ROOT\Python.CompiledFile\shellex\Drop Handler]@="{60254CA5-953B-11CF-8C96-00AA00B8708C}"

What is the express.bat in your package
It's a program NOT for noobs.​
It doesn't ask questions; simply repacks if there are folders,​
decrypt and unpack if there are xorpads​
Doesn't prompt, just runs.​
It has some preset settings.​
It won't decrypt the whole romfs.bin. Creates its own rsf.​
Due to it's nature, error prompts might be skipped.​
So I repeat,​
It's a program NOT for noobs.​



Help, my errors aren't resolved!
Do us a favor and save each other some time.​
Before showing errors,​
ensure that:​
1. you downloaded the lastest package.​
2. followed the tutorial to the latter​
3. did not use express​
If error still occurs:​
1. What Game you are using​
2. Inform me if you are using CFW or GW​
3. Tell me what error you get in game (or if you don't reach there)​
4. screenshot \exefs, \decrypted, \xorpads, \step 2​
5. show me the error page on the normal bat​
this way, easier for me to identify the error.​
Wondering if you have a faux error?​
Ctrl Find "T5"​

I was waiting for something idiot-proof like this, thank you. I assume the process is the same for VC titles? Does it work with trimmed roms?

There's somewhere how to repack the RomFS for dummies? ;)

As in rom editing then repacking?
I don't know actually, since I've never seen or used those tools until last night :x

Will this work for games, such as, Smash Bros.? I can't really keep up with all the drama with all these college essays I'm working on.

The 'latest' game that I tried and work is Pokemon X.
Haven't gone further than that ><

I also made a guide for 3ds to cia conversion if it helps, it automatically add the game manual if there's one and it can delete the decrypted files in the end if you want:

Download this : http://jheberg.net/captcha/3ds-cia-conversion-tools-7x-encryption-support-v-6/

1.If you still don't have it install 2.7 Python (not 3.4 or any other version)

2. Put your rom in the folder, run rom_tool info.bat, enter your rom name without the .3ds extension and edit the rsf file with the right informations.

3. Drag on drop your rom on the ctrKeyGen.py file, it will gnerate a ncchinfo.bin. Put it on your sd card root.

4. In the For the 3DS SD card. Open slot0x25KeyX.bin in a HEX editor and replace the 0 with the proper key. (Use Google) Put it and the launcher.dat in you sd card.

5. Put the sd card back on your console, go to System Settings -> Other Settings -> Profile -> Nintendo DS Profile and wait for the xorpads to be generated. Put the "Main" xorpads in the main folder.


Then :

If you want to remove the region lock :

- Run unpack.bat ((with or without 7.X xorpad) if you have a exfs_7x.xorpad file or not) and enter your rom name without the .3ds extension

- Follow Gadorach's instructions here : https://gbatemp.net/threads/4-x-only-cia-cfw-complete-guide.373532/page-50#post-5149465 (works with Hex Worshop, just enter 2018 in the search bar)

- Run makerom.bat, enter the filename you want (without extension).

Else

- Just run unpack-makerom.bat ((with or without 7.X xorpad) if you have exfs_7x.xorpad file or not) , enter your rom name without the .3ds extension.


EDIT : Added 7.X encryption game support. (only on gateway for now)
EDIT2 : Added the MEX.py file, for the 7.X xorpads.
EDIT3 : Fixed the exheader xorpad not found problem in the unpack-makerom bat files.
EDIT4 : Added piratesephiroth ExInjector tool :
https://gbatemp.net/threads/release-exinjector-inject-original-exheaders-into-repacked-roms.373839/

Ah well, I'll wait and hear about the results for that then. :P
It should work for everything, you'll just need to decrypt smash with the 7.x keys. There's a guide somewhere how to use the decrypting program with 7.x keys

The launcher.dat I provided (which came from Relys) will support 7.x key if you have it in your sd card as slot0x25KeyX.bin

It was originally part of my tutorial, before I decided to red line it.

I heard that you can install the 7.X encrypted games but they don't work yet. Is it true?

Why don't make an official compatibility list of the games with .rsf file and makerom command line joined ?

I can confirm a trimmed rom works.
I used a 288mb version of Super Mario 3DLand, everything went okay! Installed perfectly!
:)

This opens up even more space!

Great!!

I wasn't able to get your tools. D:

It's back up. :)

What's zat?

I just compiled and rewrote the .bats so that it links the file location,
without shifting and renaming again and again.

no idea what you're saying ><
