:This is the problem many people seem to have with the test units. From what I can tell, the only way to actually run some unsigned application (not created by Nintendo) is by programming it on a development flashcard. --[[User:Neimod|Neimod]] 01:11, 2 November 2011 (CET)

:I'm not sure why you deleted your previous post, but I agree that there are '''supposed''' to be different kinds of media (development flashcard, and copying from SD card to internal NAND) that allow running applications on a test unit. However, of these methods, only so far the development flashcard has proven to work with '''unsigned''' code. The problem lies in the fact that the unsigned development CXI image uses a dummy RSA private key to create the RSA signature, while official Nintendo development CXI images use the real deal. So as it stands, no developer can create proper CXI images for CIA importing. --[[User:Neimod|Neimod]] 14:11, 2 November 2011 (CET)

I had a look at your previous post, 3dsguy, where you have posted a download link for a CIA file. We don't know much about CIA files so it was interesting to see a file and look into it. The actual data for the app/tmd/cmd files seems to be encrypted (expected that) there's only some plain text like "Root"", "CA00000004" and "Root-CA00000004" to name a few (...) which obviously are pathes on the NAND FS. However, I've found out that the name of the files/directories (eg name of the app file:"ad7e6744") which are saved on the SD card after installing the archieve seem to be in the CIA file: Not as plain text, they're actually hex values.

* I sent him 3 pre-compiled apps at first. ( all by Nintendo ). The first two don't boot because they're not compiled with the libs/firmware running on his test-unit. The 3rd TWL NAND app, doesn't have any icon/banner/title to identify itself after being installed, and although it imports/installs succesfully, it can't be selected or launched from Dev Menu or the Home Menu. Later, I sent him a self-built application ( one not by Nint. ), it installs, boots and runs properly and it just displays some information on the screens; those are the files and images he's linked to here. [the "Hello Galaxy!!!" test-application.]

I'm not really sure about that. It would be nice if you could post another CIA file, 3dsguy, that we can compare them and find out more about it. Shall we actually create a new page about CIA files?--[[User:Lazymarek9614|Lazymarek9614]] 21:48, 2 November 2011 (CET)

* They're not unsigned. Dev/test units use a different set of keys then the retail/production units do.

+

* ''So as it stands, no developer can create proper CXI images for CIA importing.'' - What. I've sent self-built apps to test to 3dsguy and somebody else who owns a test unit running on a different firmware. They work fine. ( Although it's difficult to line up firmware revisions. )

+

* The one that actually runs was made (compiled/built) using the SDK/firmware revision matching his test-unit.

+

* He probably removed the 1st link because I asked him not to post anything with ( even potentially ) copyrighted contents for the sake of not getting this wiki associated with it, the binaries contained code from an e3 demo and the TWL/DSi SDK, we're not doing ourselves any benefit by posting it. The app that runs ( 'Hello Galaxy' ) is a self-compiled application, so it's probably not going to be mistaken for a game or other commercial application. [thus probably safe for wiki.] [[User:Jl12|Jl12]]

: They're certificates.

: It's mentioned partially under "[[Download Play]]", because it's another use of the same file format. [[User:Jl12|Jl12]]

Yes I think we should create another page made for .CIA file and move some of this page to its discussion page. But I've got another .cia file and and boots. see [[http://121.215.146.1/3ds/more_cia_stuff.rar]] for everything you may want to know about it and perhaps from this we can start a new page.--[[User:3dsguy|3dsguy]] 07:52, 3 November 2011 (CET)

: I think this is more about getting our own code running on the 3DS/CTR then it is about CIA. [[User:Jl12|Jl12]]

Lazymarek9614, those "paths" are from the cert chain and the ticket. CIA is based on WAD. --[[User:Yellows8|Yellows8]] 16:25, 3 November 2011 (CET)

@3dsguy - if the situation changes about being able to get any other test-units please let me know, thanks. [[User:Jl12|Jl12]]
