ROM Hack [Release] 3DS_CTR_Decryptor-VOiD

[sbJFn5r]

For the ORAS demo, how do you extract the code.bin correctly? Part of the exefs is encrypted in 6.x keys, and the code part is encrypted in 7.x keys.

You need to merge the two ExeFS xorpads with mex.py.

There's a script that does it for you? Where is it?

in the same package?

What package?

I found it. https://github.com/Relys/NCCH_Decryptor_v3

I am interested in knowing one thing. I read that while we are able to decrypt ROMs, we are not able to re-encrypt them.
So how exactly are people editing ROMs and making them playable again? I don't need a guide or anything since I don't see myself doing this any time soon. A simple but explanatory answer is enough.

The roms are repacked using developer's keys and certificates. Gateway can run them.

Yeah, I found it. Yay! My decryption batch script is automatic again!

Ah, I see. Is this also how Homebrew is packed or is this something different entirely?

That's something else.

Interesting. Now I'm intrigued. Is there any place where it's explained in just a little more detail how this works?

The issue we were having was makrom not properly packing the romfs. Homebrew applications don't yet have a romfs, so that was never an issue for them.

 

[piratesephiroth]

Actually homebrew elfs are packed in rom format so they can run on Gateway

Wasn't the issue we've been having related to the romfs being incorrectly packed, though? I don't think Homebrews even have a romfs at this point, I'd assume that's why they've always worked.

Okay. Ignorant question time: What is the romfs?

 

[aliak11]

I finally did it!

I'd speak that.

It's the partition of a 3DS rom that holds most of the game media.
