~~To use this tool~~, ~~proper~~ keys ~~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 goes 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.

<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>

~~This tool is practically for developer-units only.~~

~~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~~.

Well, it's been a fun 7 months so far.

~~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.~~

Encrypted, proper CXI:

~~In case some of you wonder, this does not have a RomFS~~. ~~I admit I have not delved into that yet~~.

~~Currently this has the capability to enable debug modes~~, ~~sign~~[-], ~~hash~~, and ~~create CXI files out of an ELF/AXF to~~ the ~~best of my knowledge~~.

Signatures, Hashes, ExeFS, Extended Header, Flags[-], NCCH header, and encryption are now valid. The only thing left now is the RomFS.

[-] = ~~RSA key~~ is ~~required for~~ retail/developer ~~signatures~~.

[-] = It seems flags for developer applications may differ from retail application flags, but it is not a big deal as when retail applications can be decrypted I can replace and change my flags to fit retail needs. The generated CXIs would still require an exploit to run on a retail 3DS, however.

The flags are already laid out and are valid developer flags, though.
