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

[SnakeMilkshake]

decrypt the ps backup save you will get a main file which can be read by pkhex; more important, it's importable.
only a few steps, pretty easy... done it before.

So its possible?! Oh thank goodness! Is there any kind of guide on how to do this, because I am not the greatest with this kind of stuff. You say easy but its way past me haha.

do you remember the game version at the time you make the last backup?

Send a screenshot of your folder?

I usually keep mine fully up to date, so whatever it was as of june 3rd (i believe that was the date of the backup i sent you)

Update to 5.5.
I just added a way to enter a custom minor and micro version when rebuilding a CIA file.

Edited...

Be sure your .3DS, .CIA or CXI files are fully decrypted.
Doesn't have any space or special caracters in their names (such as é or à).

You're not putting the extension in the file name you're typing into the command prompt, right? If you're trying to unpack Game.cia then you only type "Game" and leave out the .cia

Will added it to the readme, even if written in the question...

Yeah, I goofed a little while ago and got the same behavior as @LinkSoraZelda, I kept adding the extension (tab complete) and it keeps saying the extraction completed but nothing actually happened. Then I noticed my mistake, removed the extension and it worked fine.

Nope.

Hey, you know of any homebrew i can use to decrypt just a single partition (exefs in this case)? Because dumping romfs takes forever and all i need is code.bin...

 

[Sora6645]

when i try extracting a file it wont extract files. i am running on windows 7 can upload your new version of this? https://puu.sh/smPVV/db11b0be97.pngi type in the name of the game and it doesnt go anywhere. Any help would be nice!

 

[Sora6645]

nvm i got it to work!

Do all of these steps still work since switching from RxTools to Luma cfw? Namely the first step - dumping the game. How on earth is this done nowadays? Can I do it on my PC instead of using the Gateway menu nowadays?

Impressive hacking method, I will probably use this when I get my new 3ds

Hello People, im trying to figure out how to properly use the "rebuild a cia" option in Hackingtoolkit. i put cr in the command prompt, and it tells me its building, and when it finished, there is no cia file, except some bin files like the header and romfs, with custom in front of their names. Is that supposed to happen or is there something i'm missing?

Thanks for "that thing" Asia81. This have really helped me

Updated to 5.6. Delete the previous version, and install the new SetupXX, as always.

Disclaimer:
All I do is firstly for a personal use.
I'm not a C coder and I don't have any C skills, I do all in batch script.
If you hate/don't like that, then don't use it, or any of my tool scripted in batch.
When it work form me, I don't see why I will lose my time to code it in C (anyways I don't know how).
Even if I would like do it :/

I just improved the MassExtraction Script.
You can now choose to decompress (or don't) all code.bin files at once, or be asked for each.

Hello, I have tried to apply the english patch to Dragon Ball Heroes Ultimate Mission 2. I have extract the rom, replace the folders and rebuild the rom, but give me a black screen when I try to load it. I have noticed that the ID of the rebuild rom is unknow so I think I am missing one step. I had the same issue when I tried to edit Ace Attorney Dual Destinies, the rom information was all in blank and didn't start. I have tried to encrypt but fails

Thanks!
