The Nintendo 3DS utilizes a similar title-based organization as seen in the Wii and DSi platforms. The same update server is being used as was with the DSi. When using SSL, the update/shop servers must be accessed via SSLv3. A total of 6 AES engine keyYs can be used for crypting the ticket titlekey. Therefore, there's a total of 6 ticket common normal-keys. This keyY is specified by the ticket comon-key index, however retail system titles normally only use index 1.

The organization of Title IDs has not been documented fully yet. Region info isn't stored in title IDs however there does appear to be evidence that the regions are sequential, similar to how Wii System Menu Updates are ordered: JPN USA EUR KOR and CHN (introduced with the DSi). 3DS has one additional region: TWN.

Note: The terms 'Title ID', 'Partition ID' and 'Media ID' are interchangeable.

The 3DS retrieves system tickets with SOAP request GetSystemCommonETicket, instead of directly downloading the cetk with HTTPS. The cetk is still accessible via HTTP, however 3DS doesn't use direct HTTP for this.


TitleID Structure: 0xCCCCABCDLLLLLLRR

  • CCCC defines the console platform (4=3DS, 3=DSi, 1=Wii)
  • ABCD defines the type of the title, see 'Title Type Identification Key'
  • LLLLLL For CTR titles, this is the title's 'Unique ID'. For TWL converted titles this is in two sections grouped as SSLLLL. SS is the old title identification used by the DSi and is made redundant by 'ABCD'. LLLL is the TWL title's 'Unique ID'. There are restrictions on the Unique ID, see below for more info.
  • RR contains various info depending on title type see 'RR'


Title Type Identification Key:

There are three main title types for the 3DS, 'System', 'Application' and 'TWL'(Converted DSi Titles)

For: 0x0004ABCDXXXXXXXX

System Titles:

DIGIT ACCEPTABLE VALUES
A 0,1,2,3
B Any Digit
C 1,3,5,7,9,B,D,F
D Any Digit

This CTR title type (which covers a whole group) is eligible to be updated during a System Update. System Titles can only be installed to the CTR NAND.

Application Titles:

DIGIT ACCEPTABLE VALUES
A 0,1,2,3,4,5,6,7,C,D,E,F
B Any Digit
C Any Digit
D Any Digit

NOTE: If 'A' and 'C' both fill the 'System' title requirements, this title will register as 'System' Instead of 'Application'. Unlike System, Application subdivides again into more types. Application Titles can be installed to the CTR NAND and SDMC or flashed to a CTR Card.

TWL Titles:

DIGIT ACCEPTABLE VALUES
A 8,9,A,B
B Any Digit
C Any Digit
D Any Digit

TWL Titles can only be installed to the TWL NAND.


Unique ID Restrictions:

For the CTR titles, there appears to be is a correlation between Unique IDs (UID) and 3DS 'title types'. For developer titles this is known(shown below), and retail titles *appear* to follow suite. It is unknown if this correlation is enforced on retail units, or if it is just for organisation purposes.

TITLE TYPE UNIQUE ID RANGE
System 0x0 - 2FF
Application 0x300 - F7FFF
Evaluation 0xF8000 - FFFFF
Prototype* 0xFF000 - FF3FF

*On the home menu, titles with UIDs within the 'Prototype' range, appear on the home menu after install without the gift fanfare.

RR Recognition Key:

For: 0x0004XXXXXXXXXXRR

The RR in CTR Titles, just provides extra information, usually about how the title is handled.

RR in System Titles:

RR AFFECT
00 System Application
02 System Title (Core version 0x2)
03 SAFE_MODE System Title (Core version 0x3)

Normally on retail SAFE_MODE ARM11 CXI titles can't be launched, since the system core version doesn't match the CXI exheader core version.

RR in Application Titles:

RR AFFECT
00 Normal Application - Cartridge and regular eShop titles are such titles.
01 Unknown - Found in Demos, Debug Updates and some DlPlay Child CXIs.
02 CTR NAND Application - Like normal Application titles but they are installed to and run from the CTR NAND.

The RR in TWL titles, is the region code. The region code list has been shortened from the original DSi region list (see DSiBrew) to the below list to fit with the three broad regions of the e-Shop. (i.e. TWL titles downloaded from the Australian e-Shop have a region code of '56' as oppose to the DSi Australian DSiWare region of '55')

RR in TWL Titles:

RR TWL APP REGION
41 No Region (Found in TWL System titles)
45 America
4A Japan
56 PAL(And other non Japan/USA regions)

NATIVE_FIRM and SAFE_MODE_FIRM for the initial versions are exactly the same, besides core-version fields. When a GBA VC title is launched, AGB_FIRM is launched to handle running this title. GBA VC savegames stored under SD card /title/<TID>/data use a custom format, this is handled by AGB_FIRM.

This titleID-High is also used for gamecard applications. The CXI for retail applications available via gamecard and eShop are exactly the same, except the exheader differs. For SD applications exheader_systeminfoflags.flag bit1 is set, for gamecard applications this bit is clear. The ExeFS and RomFS are exactly the same for the gamecard/eShop versions. The eShop version of the CXI has additional padding.

0004008C - Add-on Content (DLC)

These are titles which provide downloadable content to a specific title. The reason why these titles can only be purchased in game, is because all DLC content is under one titleID, downloading via the eShop would download all DLC content. And because all DLC content is under one title ID, they are viewed as one title in system settings, and individual DLC can only be deleted from within the game which uses the DLC.
