Talk:CIA

Good work Lazymarek9614, Now 3dsexplorer on the svn is 0.73 (you can download it from the beta link) supports cia. --Elisherer 21:34, 10 November 2011 (CET)

@Elisherer where is that beta link?--3dsguy 02:39, 11 November 2011 (CET)

3DSExplorer, bottom of the bage. --Elisherer 08:09, 11 November 2011 (CET)

"Each section is cleartext for dev CIAs, for retail CIAs the APP data is encrypted."

Dev/Production CIA use the same specification. So I'm not sure what you mean by this.

The "ctrtool" on the CXI page already parses the CIA format, why re-invent the wheel?

"CIA files can be created with the Nintendo 3DS SDK and installed on the 3DS test units by the Dev Menu."

Please keep the focus on documentation of the spec., we don't want to explain things from the perspective of SDK users- but for someone that knows (potentially) nothing about the 3DS. The SDK does not tell the whole story of most file formats, and most people don't need to know what the SDK can do for them but what they can do without the SDK. - Jl12

"Dev/Production CIA use the same specification. So I'm not sure what you mean by this. " I originally worded it that way on the page because both CIAs 3dsguy uploaded had cleartext APP data, thus I wasn't sure if CTR-SDK had an option for encrypting the dev CIAs. I don't get why Elisherer re-implements about everything ctrtool already does either... --Yellows8 05:26, 12 November 2011 (CET)

- Depending on which one it was, the link that was removed at first, was a old presentation from e3. It's just out dated enough that the cia format probably hadn't been finalized. Anything before firmwares 0.10.0 - 0.11.0 neither use LZ compression nor encrypt (!) but - except the use of keys, the SDK now produces .cia with close to retail specs. Jl12

If you like working with the windows command line be my guest. I got more progress looking at the files with 3dsexplorer... (And i'm not re-inventing 3dsexplorer didn't support cia so I added it, I will continue fixing the structure to be as accurate it can be) --Elisherer 09:48, 12 November 2011 (CET)

- I was thinking more the wiki and the "documentation" of the structures then 3dsexplorer tool. (I thought this was based on binaries, though) Jl12

I personaly like a command line tool more, but it's really annoying to have for each format another tool. Shall I create a new page for the certs and tickets?--Lazymarek9614 15:06, 13 November 2011 (CET)

The format of the certs/tickets seem to be the same as before,(besides the new signature types already described on the TMD page) not really necessary to create pages for those.(Any info on what cert is used to sign what should be on a /sys/cert.sys page or so later IMO) Elisherer, you're re-inventing the wheel aka re-implementing CXI/CIA code which ctrtool had for months, which is a waste of time IMO. --Yellows8 19:24, 13 November 2011 (CET)

Yellows8, I didn't write any new code for the CXI/CCI/TMD/CIA opening, I just copied it from the ctrtool (as I mentioned when I just written the app). The rest (which is the SAVE flash) became the prime goal of the app and with it I discovered a lot of new information. I try implementing most of the file structures we know so it would be more accessible to everyone (Hoping it would help solving more mysteries). I know that now it's not clear why 3dsexplorer opens these sort of files but with time more information will come and it will grow to extract more important information. I hope you understand. --Elisherer 20:27, 13 November 2011 (CET)

Sorry guys, this discussion doesn't really has anything to do with the CIA format. Please choose another page for this or stop it now. @ Yellows8: I think it's not important to create a new page for it too, only some links to the TMD format and wiibrew wiki are necessary.--Lazymarek9614 20:44, 13 November 2011 (CET)

Other than that TMD code, that CXI/CIA code looks nothing like the ctrtool code to me - but whatever. --Yellows8 22:07, 13 November 2011 (CET)
