ROM Hack [Tutorial] How to Decrypt, Extract & Rebuild a CIA

[Asia81]

I don't know how mac/linux work for installed tools, so no I can't help you more.
Be sure to have the setup installed.
Be sure the cia is fully decrypted (cia decryptor deep).

File not found mean the script can't find the installed folder:

Impossible de trouver C:\Users\Asia81\Desktop\Test\DecryptedPartition1.bin
Impossible de trouver C:\Users\Asia81\Desktop\Test\DecryptedPartition2.bin
Impossible de trouver C:\Users\Asia81\Desktop\Test\DecryptedPartition6.bin
Impossible de trouver C:\Users\Asia81\Desktop\Test\DecryptedPartition7.bin

If it was a problem with the cia (like a space in the name), it should be an error like that:

error: could not open input file!
error: could not open input file!
error: could not open input file!

Be sure the setup file is correctly installed

I am able to decompress/extract the roms just fine manually and the thing is installed so i don't know why it's complaniing, it has to be entirely decryted, itwas already likely zerokeyed before but it's still giving those wonderfully annying messages.

I tried to change the title id of my pokemon omega ruby game (EU) "11c4" to "0ff0" as well as changing the serial to CTR-P-TEST (as it is jsut another test i did xD).
Following i checked:
- original cia was working
- decrypt9 told me that cia is decrypted allready
- SaveDataFiler & co are displaying both cias correctly (title id + serial)

But when i start my changed version (title id: 0ff0 and serial CTR-P-TEST) i just get a error message displayed.
Is there a way to fix this?

Not working for me either:

And?
It's too hard to write?
And what are you doing in the programfiles folder?

Now I have to wait for the patches/DLC part...

Now I have to wait for the patches/DLC part...

the patch part should be ready, I already managed to rebuild any updates (check my mk7 edited release)
DLC should not be long too

So I tried to decrypt Kirby Planet Robobot (cia) and it says I need a TitleID. The problem is, it hasn't come out yet, so its not on 3DSDB yet. How do I dump it myself?

 

[Asia81]

3ds = Gateway Rom Patcher
Cia = Check with Title Manager or Fbi

Your setup exe extracted straight to program Files so I've been working from there, and that's screenshot of my program Files folder where it all is: I've tried typing just the name and dragging and dropping so it has the full path but it fails - I can assure you it's been decrypted though, it took forever. It's not a bad cia because I got it with id and title key using funkeycia, so I don't know what the problem is.

IF you didn't find it yet: 0004000000183600

I got it a while ago, but thanks anyways.
Now all I have to do is figure out this encryption stuff on all the files. :/

Uh... I just installed the cia fine.
I didn't try the decryption itself, but if the cia is installed fine, I don't see why my decryption won't work

That's not what I meant. Almost all the files in the ROMFS are in .cmp format.

Oh sorry x)

pretty easy to extract, cmp

How?

 

[Asia81]

It'z LZ11 compressed.
Use:
- DSDecmp GUI in 3DS Explorer (it's what I used).
- LZ11 decompression in MSBT Editor.
- lzx.exe (Included in darctool.py package).

I'm having trouble dumping my clean freshly made .cia of Maplestory 3DS (J) from my cart. I decrpyted it with decrypt9 and attemted to dump it by typing ciae and hitting enter, then I put the name and it ask y/n and regardless of which option I choose nothing shows up extracted. The program says please wait... and extraction done! all in about a second but I don't see any files.

What am I doing wrong?

Edit: I didn't run the setup.exe go figure. It works now thanks.
