Wonder if anyone could help me...

I have downgraded my n3DS and have emunand with FBI. I got Yokai Watch EU from a certain site,but when I try to install it in FBI,it fails straight away. I unrawred the file and it was already a CIA one

rxtools allows u to install unsigned cia, this should work. Are you using fbi.cia? The .3dsx might not work correctly for some reason, just inject fbi to the h&s with rxtools

Thanks a lot for this tool! :) Works great, but for some reason my rxTools, no matter how I boot it(ctr, browser, HBL), just directly goes into rxMode emuNAND, so I had to use Decrypt9 lol

But anyway, works great!! :D Cheers

That isn't what I meant xD After I boot into CTRboot manager, I open rxTools, but it doesn't go to rxTools menu. It directly goes into rxMode emuNAND.
If you hold L once you see the Rxtools image, it won't take you into rxmode emuNAND but instead you will be on the rxtools menu.

Riku your tool is the best for creating a cia. But can you add modifying rom features like unpacking xorpads and repacking them to a new 3ds rom or a cia?

3DS 2 CIA HowTo with 3DS Simple CIA Converter

Click "Show"
3DS 2 CIA with 3DS Simple CIA Converter

Download the program and follow the discussion on GBATemp
[Release] 3DS Simple CIA Converter

So what is it?

It's a Windows program to convert 3DS roms to CIA files, those CIA files can then be used to install
the converted 3DS rom on Gateway or Custom FirmWare (CFW)
It can convert Multiple roms at 1 go :)

Why a guide if it's so simple?
Why are there guides for everything?, for example internet for dummies, etc...
A guide with ugly taken pictures and badly taken screenshots sometimes say more then 1000+ words!

So let's start
Unzip the rar to wherever you like (I like to place it in a folder i recognize easy d:\3DS_2_CIA)
(The slot0x25KeyX.bin file is not needed, just ignore it :P )

3ds2cia01.png



Find your roms you want to convert to CIA and place them in the rom folder (in my case: d:\3DS_2_CIA\roms)

3ds2cia01a.png


Start "3ds_simple_cia.exe" and choose "Create 'ncchinfo.bin' file" and if you want, check FW Spoof.
- FW Spoof is only needed if your EmuNAND is lower then the Firmware the game needs to run



3ds2cia02.png

3ds_simple_cia will ask for a folder, It will automaticly pick the roms folder, so just hit the button folder select (see picture) NO need to type anything!

3ds2cia03.png


Then it will ask for a folder where to store the ncchinfo file, just hit the save button (see screenshot) again, you don't have to type anything!

3ds2cia04.png


Important: LEAVE "3ds_simple_cia" window OPEN, don't close it (the truth, yeah you can close it if you want :P but it's easier to just leave it open anyway :D)

Now, remove the SD/MicroSD from your (N)3DS(XL) and connect it to your computer
Copy ncchinfo.bin to the root of your SD card, as shown in the pictures!

3ds2cia05.png


to

3ds2cia06.png


Safely remove the sd from your computer and place the sd back in your 3ds and boot into "rxTools Menu"
As you see in my picture i use ctrbootmanager to do that!
(Note, you can also use Decrypt9 to generate Xorpads, but i will not use that)

3ds2cia06a.png
3ds2cia06b.png


Now go to the tab "Decrytion" and press "A" to enter it and here select "Generate Xorpads" and wait for the screen to finnish!

3ds2cia06c.png
3ds2cia06d.png


At the end it's possible you get an error "100%Error opening SDinfo.bin" Just ignore it and press "A"

3ds2cia06e.png
3ds2cia06f.png


Now turn off your 3DS by pressing and holding "Select" and remove your sd and connect it to your computer
You see multiple xorpads, depends on how many 3DS roms you placed in the "rom" folder. Select ALL xorpads
and move them to your xorpads folder where you placed 3ds_simple_cia.exe.

3ds2cia07.png


to

3ds2cia08.png
3ds2cia09.png


Now go back to your 3DS Simple CIA Conveter program (you sure have left open, if not restart it and make it look like the picture!

3ds2cia10.png


Select "Convert 3DS ROM to CIA" a windows pop up to select a folder, leave it like it is and press "Select folder"
No need to type anything!

3ds2cia11.png


A few seconds or minutes later you will see a small windows pop up saying "Finnished" press "OK" and close the program

3ds2cia12.png


Now go to your "cia" folder and you will see your converted 3ds roms as cia files

3ds2cia13.png


Install with FBI or BBM or DevMenu, whatever you like in your Emunand (CFW)

3ds2cia15.png
3ds2cia16.png
3ds2cia18.png

After I install my .cia, I can erase the .cia that is in the SD Card or not?

[EDIT]
Using Decrypt9 for XorPads:


Copy ncchinfo.bin to the root of your your 3DS SD and boot your 3DS into Homebrew Launcher (I use MenuHax)

DSC05846.jpg




Select Decrypt9 (i use Decrypt9UI) and go to XORPAD with your L or R buttons
Under XORPAD select NCCH PADGEN

DSC05847.jpg




As you can see, you need slot0x25KeyX.bin (search the net)
I don't know if seeddb.bin really is needed. (The rom i used didn't needed it anyway (LEGO_Marvels_Avengers_EUR_MULTi7_3DS-PUSSYCAT))
When NCCH Padgen says succeeded! you can press B to go back to the main UI and then shut down your 3DS., rest is the same, copy to your xorpads folder from 3ds simple cia etc...

Also added "Decrypt9UI" for Xorpad generation, with some pictures.

Can I Install it using DevMenu?
If you mean the program, then no, it's a PC utility.
If you mean the CIA it spits out, then yeah. What'd be the point of converting it to CIA if you couldn't install it?
