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

BigPigeon · Jan 2, 2020

So I've been messing around with different ways to convert from .3ds to .bin and have given HackingTools a try. I used ctrtools before to extract a romfs.bin and it worked just fine, however since that system doesn't seem to convert back to .3ds I'm experimenting with this too.

Here's the problem that I'm seeing.

HackingTools9DS converts from .3ds to .bin, no problem. But when I try to convert back to .3ds, the output file is called "<Filename>-Edited" and it's much smaller than the initial .3ds file that I converted from.

Is there a step that I'm missing here? I'm literally doing the bare minimum of inputs. Nothing has been edited within the .bin files themselves, all I'm doing is extracting and rebuilding (Using the D and R commands, respectively).

Screenshot below showing the exact layout of my HackingTools folder

-AwakeningOriginal.3ds is the .3ds file that I'm working from
-DecryptedRomFS.bin is the extracted .bin that I'm trying to rebuild. It's file size is identical to the roms.bin that ctrtools created from the same .3ds ROM.
-Awakening_Edited.3ds is the rebuilt ROM. Note the file-size difference. I also didn't instruct HackingTools to add the "_Edited" part to the filename, it did that by itself. Needless to say it doesn't run.

EDIT: Figured this one out myself. I was using the V12 release of HackingTools instead of V9, which is the one that is compatible with decrypted ROMs. Tried V9 and it worked like a charm.

Ok!
I thought that maybe one could decrypt the game and encrypt it back to a 4.5 compatible format.

nowhere indicates where the .cia should be to be detected by the program. Help!! I put the .cia in the same location of the .exe and it quickly says that was extracted but actually nothing happened.
EDIT: I guess the program has a limited character length. I did it with 10 now and worked like charm, but now I have problem rebuilding to a .cia. It showed up something klike "Makerom.exe - system error" "ucrtbased.dll was not found". Other error showed too something like VCR....dll . Help!!

hackingtoold3ds does not extract ultra moon succesfully. It extracts nothing while being happy that it extracted succesfully. How do i solve this? I've been trying to edit it with pk3ds for days now...

Yes it's a decrypted 3ds file, yes im using the right v9 version, yes it has a small name with no spaces, yes i run as administrator, yes i installed setupus beforehand. None of the fixes suggested work. Clap.

Edit: Nevermind I figured it out. I'd delete this if I could.

I've succesfully managed to extract and rebuild ULTRA MOON (which is something i haven't seen anyone be able to do yet since there are no tutorials or fixes for it anywhere and everyone just accepted it's impossible).

My rom of ultra moon is labelled as a .3ds file, but that's not what it really is. I noticed, by opening citra, that its true file type is NCCH, not 3ds or other more common types of rom. That might be the case with your MapleStory too. If it is, To Extract and rebuild NCCH files, hackingtools does not work. Search for a program called GabrieloRomTools, it can handle NCCH (this program is present in a thread in this very forum). Don't forget to use the NCCH sectiion of that program even if the rom is labelled as something else.

Do you know which would be the correct entry for VS2017? I cannot find common tools within the new installer!

For those who (still) have problems with the makerom.exe missing/error ucrtbased.dll and VCRUNTIME140D.dll files rebuilding a .cia file with the V11 version
Solution: I downloaded both dll files (search on Google) and placed both DLL files into the C:\Program Files (x86)\HackingToolkit9DS folder.
Rebuilding a .cia was no problem anymore.

This might be a N00b question (but he, i'm learning)...

I have 2 .cia files 1) PokemonSun.cia & 2) PokemonSunupdate v1.2
Is it possible to extract and rebuild both into 1 .cia file so that the original PokemonSun.cia has v1.2

Hi, when I try to repack the cia, the application literally slows down my computer a lot and then after a little while it freezes up. can you fix it?

Fix is simple: Get a better PC. Your CPU is at fault and too slow.

dude it was Originally Windows 7 it shouldn't be that bad. I don't think cpu has anything to do with this.

Seriously how about this? The dll's needed all have multiple versions out there, many of which don't work, and also depend on which specific version of Windows you're using.
I've tried on 7, 8.1 and 10 and cannot find a combo that works on any of them. Either provide them with it, or at least put up a non debug build...

Hi, guys!
Plz advise how to edit image.bin files?
I exported this rom, but i'm unable to view or edit images.
The Game is True Remembrance (Kioku no Kakera) for 3DS

universales · May 24, 2020

When trying to create any cia file, the program gives me an error "0xc000007b".
Seems to be a problem of windows 10 x64
Anyone else has happened?
Any solution?

How i can Change the Game Icon File icon.bin ?

wad11656 · Jun 14, 2020

(I asked this here:
https://gbatemp.net/threads/hatsune-miku-project-mirai-update-error.531440/#post-9094546 )

Basically, I have a handful of games that I think were built using the wrong minor and micro versions. So those games always nag me to update, but when I try, there is always an error.

So how do I know what minor and micro versions to use when I rebuild these games so they stop nagging me for updates?

All I get from extracting the .cia is a bunch of bin files. How do I get into those?
