To generate a correct CXI (when supported), proper keys will need to be supplied. For developer-unit keys, you need to be an official Nintendo 3DS developer, and have access to the official Nintendo 3DS SDK. For retail-unit keys, don't even bother.
+
The CXI generator has not been released yet, please understand it is under development. I apologize for adding in the possibility of using retail RSA keys; they would be so hard for us to get it wouldn't even be funny having them. However, when homebrew is available to this community the output should be usable, as a homebrew loader would not check the signature.

Banner output has been checked. It is proper data if the program is used properly. The same is for the ICN.

Over the past weeks I have been working on Project CiTRUS (citrus). Currently this tool boasts the capability to output "proper" Nintendo 3DS (CTR) BaNneR and ICoN files using my XBSF format.

Since v0.2, a readme is not really necessary anymore. I've included helpful text inside each tab in the CiTRUS window to do things on-the-fly without needing to switch between notepad and CiTRUS.

I am proud to reveal what this upcoming project is today.

It has come to my attention that there is no GBATemp Homebrew Bounty. At the time of writing the news above (~3 weeks ago) I was under the impression it would happen again.
  −

  −
Regardless by saying "at" I was implying "by". I will still release this next version, to be dubbed "CiTRUS Ultimate". Currently I do not have an estimate of when the release will be exactly, but I am hoping for sometime next week since I am getting positive results.

I know, due to the nature of how I am "unknown" to the scene, I may be considered a liar or fraud. To assure you that I am honest with my work I will enclose a download to a work-in-progress 3DS-mode Homebrew ("Hello World") CXI I developed using CiTRUS Ultimate.

I am not dead! I apologize for my absence. I wanted to have enough data this time to make solid and more presentable data.
      −
<del>I understand some of the misinformed users of gbatemp may think this is developer-only but in fact it can be retail signed, provided the right RSA keys. In my demo, I used a fake RSA key. When using this program, I provide you an option to specify your own RSA keys for signing. No illegal keys will be provided. The CXI is a format used by both retail and developer 3DS's, not just developer!</del>
+
For the past month and a half I have been learning much more and I've been able to successfully compile CXI (CTR eXecutable Images) with accurate raw data. Last time, my CXI was (in all respects) only structurally valid; the data was not so much as valid as I was thinking. This time, however, I've been able to test the raw data and have progressed the output to be a 1:1 valid binary. I am working on proper encryption, but for this demo/progress update it now has correct structure, flags, signatures, and raw materials to be encrypted into a CXI. In other words, I've made a valid raw form of CXI for this progress update.
   −
This tool is practically for developer-units only.
     −
<del>Please note that this CXI has not been tested for loading but it has valid structure, a valid ExeFS (contains ARM11 code, banner, icon, and logo) and has been accepted in transformations to other formats. To the best of my knowledge this is very close to a proper CXI, if not a proper one already.</del>
+
For those curious to see that I'm not making blind claims I'll attach a new download for a fully unencrypted (raw), but valid, homebrew CXI :
   −
After some testing between 3DSGuy and I we have discovered a few problems with the test application. The application appears to be properly signed/signable, and it is able to pass Nintendo's validity checks up to 92% of the installation.
     −
In the initial release of this new feature in CiTRUS I will only include very simple options, but if I see users are enjoying this program I will add more to it.

      −
In case some of you wonder, this does not have a RomFS. I admit I have not delved into that yet.
+
I am still working on encrypting it properly, but now I can show valid coding base progress. I've formatted this CXI to outline the CXI structure while being unencrypted. You may notice I did not include a logo binary in the ExeFS. This is because I'm not 100% sure if it is legal to distribute that (my guess is not, though) so I'd rather not post that here just to be on the safe side.
      −
I hope to finish fixing the issues soon, but it is very close to being able to pass the checks when importing to the Nintendo 3DS, making it through a solid 92% of the installation currently.
+
Now, with this presentation, I am showing valid structure ''and'' valid raw (unencrypted) data. I hope to soon figure out how to properly encrypt CXI to use with 3DS software.
   −
This doesn't mean the CXI fake - this means it not yet proper. There is a big difference between fake and not proper. I wouldn't release more than the concept output of this tool without testing first. The output CXI was a test bed, which wasn't perfected yet and so I will work on perfecting this CXI before releasing this portion of CiTRUS.
