hi

Where is the extraction files located?

 

[Flannoit]

For people trying to rebuild CIA and are getting the makerom error, download the most recent version of makerom from github and replace the one in the folder. it fixed my problem. seems like the issue is that the makerom exe provided straight up is broken.

Thanks for the tool Asia81

What does it mean when after extracting a CIA you get a set of .bin files instead of a set of folders?

extract complete but i not found file extract

 

[princessdmg]

After I extract either a .3ds/.cia file using the right command for it I only get .bin files and no folders. Any thing I was doing wrong? I am using the v12 English one

Unfortunately I think the tools are broken. It said it was able to rebuild the files into a cia file, but all it did was create CustomRomFS.bin, which is completely unusable for me since I barely understand this stuff at all.
I don't know why this stuff is so complicated. I just wanted to play a randomized ultra sun game but the stupid randomizer saves it as a cxi file instead of a 3ds or cia file.

 

[MiShi_Official]

So I'm getting .Bin files instead of folders, is there a specific program needed to extract models/textures from it?

This tutorial will try to help you extract a 3DS|CIA|CXI file to change its content, and will also explain how to rebuild your game once edited.

Thanks a lot to Ericzander & BullyWiiPlaza for their help to translate this tutorial in english
(Because I'm French, it’s difficult to make a full tutorial in a good english...).
If anyone see any typo or something wrong with my english (in the setup, the script, the tutorial...) let me know!

SUMMARY

- What you need
- Prerequisites
- Decrypting
- Extracting
- Editing
- Rebuilding

What you Need

• An encrypted 3DS|CIA|CXI file (It can either be a game, game's update, system application, but anyways not a DLC file nor a DSi Ware!)
• WinRAR, or another archive extractor
• HackingToolkit9DS -> Click Here

Prerequisites

Install the new SetupUS|FR.exe of HackingToolkit9DS as a common tool:

Extracting

Open HackingToolkit9DS:

Don't forget, your file(s) should not have any spaces in its(their) name(s), nor special characters, like é or à.
You want extract PokemonMoon.3ds ? Just write PokemonMoon.

If you plan to extract a 3DS file:
Write the "D" command, and enter the name of your .3DS file WITHOUT its extension.

If you plan to extract a CIA file:
Write the "CE" command, and enter the name of your .CIA file WITHOUT its extension.

If you plan to extract a CXI file:
Write the "CXI" command, and enter the name of your .CXI file WITHOUT its extension.

Wait while it's extracting.

The ExeFS content will be extracted in an ExtractedExeFS folder.
The RomFS content will be extracted in an ExtractedRomFS folder.
The DownloadPlay content will be extracted in an ExtractedDownloadPlay folder.
The Old3DS update will be extracted in an ExtractedO3DSUpdate folder.
The New3DS update will be extracted in an ExtractedN3DSUpdate folder.
The Manual will be extracted in an ExtractedManual folder.
The 3D Banner will be extracted in an ExtractedBanner folder.

The work here should be ok.
Now you’re able to edit the game, go to Editing.

Editing

Do what you want.
Edit music, textures, banner, icon..
If you follow this tutorial, you know what you want to do.
Once it's finished, rebuild your game.

Rebuilding

If you extracted and plan to rebuild a 3DS file:
Open HackingToolkit9DS, write the "R" command, then enter the name you want for the output file.

Enjoy!

If you extracted and plan to rebuild a CIA file:
Open HackingToolkit9DS, write the "CR" command, then enter the name you want for the output file.

Enjoy!

Troubleshooting

Before report an issue, be sure:
- Your 3DS|CIA|CXI file is clean and not decrypted by Decrypt9 or GodMode9.
- Your 3DS|CIA|CXI file doesn't have any space or special character in its name (such as é or à).
- Your 3DS|CIA|CXI file is in the same folder as HackingToolkit9DS.
- You're not trying to extract the file in the ProgramFiles folder (where installed core files are).
- To write or don't write the extension of your file when specified.
- To have installed the setup package for your language (SetupXX.exe file).

Hi, thanks for the tutorial. I have a problem. Every time I extract my games, they never have the folders and instead just have the bin files. Please help me -_- I tried with decrypted, encrypted, cia, 3ds and none of them worked :'(

Hi! I tried modding the binding of isaac rebirth textures and sounds, but I don't understand how rebuilding .cia works. I reinstall the game with the .cia I rebuilt that has "modded textures and sounds" and it did not worked. Did I missed something or do I have to use an older version of hackingtoolkit9ds?
