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.

Notes from users[edit]

~~This application may not generate completely perfect files yet.~~ Banner output has been checked. It is proper data if the program is used properly. The same goes for the ICN.

General information[edit]

Introduction[edit]

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.

You may notice that creating these formats is not yet available in any other released tool. Over the course of time I will do my best to add creating new formats of 3DS files among various other calculations if I see users are liking the program.

If you have v0.1 please update it! There are new bug fixes, GUI changes, and updates! It is also more n00b compliant than the previous version. (now has a lot of help text)

I do not include an editor for the image formats, however, I do include an example of each required file for generating a test banner/icon. I do this not to troll, but rather in the hopes that it will encourage other talented users to make programs for the 3DS.

USE[edit]

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 (or your favourite text editor) and CiTRUS.

INPUT:

1x XBSF (Xtended Banner Specifications(Spec) File)
2x CTPK (CTR Texture PacKage)
1x BCWAV (Banner CTR Wave)
1x CBMD (CTR Banner Model Data)

OUTPUT:

1x BNR (Optional)
1x ICN (Optional)

ISSUES[edit]

I don't think there is any, but since this is a beta please report to me if there are issues that come about!

UPCOMING[edit]

5/7/2012

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

Encrypted, proper CXI:

http://www.mediafire.com/?hcm1p6fq4x7q14o

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

[-] = 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.

UPDATES[edit]

Version 0.2:

Fix: "Polish" changed "Portuguese"
Fix: Can now Set region to Taiwan
Fix: Can now Set rating to true

Add: Colour scheme of menu items to match colour scheme menu bar
Add: ComboBox for regions and ratings
Add: Checkboxes instead of true/false typing
Add: Automatic saving before building
Add: Banner writing progress bar/notification of finishing
Add: Help box incorporated into each tab (except title name/publisher tabs because those are not so complicated)
Add: Name now reflects what's on here (CiTRUS) and version number (v0.2)

-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.
+Well, it's been a fun 7 months so far.
-<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>
-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.
+Encrypted, proper CXI:
-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.
+http://www.mediafire.com/?hcm1p6fq4x7q14o
-In case some of you wonder, this does not have a RomFS. I admit I have not delved into that yet.
+Signatures, Hashes, ExeFS, Extended Header, Flags[-], NCCH header, and encryption are now valid. The only thing left now is the RomFS.
-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.
-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.
