0x00090000 | 0x8 | 0xE | This contains a u64 ID, used by processes using NWMUDS:InitializeWithVersion. The first word is the same as LocalFriendCodeSeed, while the latter is a separate word. |
0x00090001 | 0x8 | 0xE | Same content as 0x0009000? This console-unique u64 used by GenHashConsoleUnique is generated with the LocalFriendCodeSeed and with random data |

0x000A0000 | 0x1C | 0xE | Username |
0x000A0001 | 0x2 | 0xE | Birthday (u8 month, u8 day) |
0x000A0002 | 0x1 | 0xE | Language |
0x000B0000 | 0x4 | 0xE | CountryInfo |
0x000B0001 | 0x800 | 0xE | Country name in UTF-16, every 0x80-bytes is an entry for each language, in the order of the Language table below (not all entries are set) |
0x000B0002 | 0x800 | 0xE | State name in UTF-16, every 0x80-bytes is an entry for each language |
0x000B0003 | 0x4 | 0xE | Pair of 16-bit values, meaning unknown but related to address (ZIP code?) |
0x000C0000 | 0xC0 | 0xE | Restricted photo exchange data, and other info (includes a mirror of Parental Restrictions PIN/Secret Answer) |
0x000C0001 | 0x14 | 0xE | Same as above? |
0x000C0002 | 0x200 | 0xE | ? |
0x000D0000 | 0x4 | 0xE | u16 at offset 0x0: EULA Version which was agreed to. |
0x000E0000 | 0x1 | 0xE | ? |
0x000F0000 | 0x10 | 0xC | Unknown, used by NS on dev-units for svcKernelSetState, where Type is 6. During NS startup on debug-units, NS compares the u32 from +8 in this config-block with the APPMEMTYPE. When those don't match NS starts a FIRM-launch (with the same FIRM titleID as the currently running one) to boot into a FIRM with the APPMEMTYPE value from this config-block |
0x000F0001 | 0x8 | 0xC | ? |
0x000F0003 | 0x1 | 0xC | ? |
0x000F0004 | 0x4 | 0xC | The first u8 is the System-Model value, the last 3-bytes are unknown |
0x000F0005 | 0x4 | 0xC | The first u8 indicates whether network updates are enabled. (However, NIM only checks this flag with developer UNITINFO). |
0x000F0006 | 0x28 | 0xC | ? |
0x00100000 | 0x2 | 0xC | ? |
0x00100001 | 0x94 | 0xC | Stores Parental Restrictions PIN/Secret Answer and other info |
0x00100002 | 0x1 | 0xC | ? |
0x00100003 | 0x10 | 0xC | ? |
0x00110000 | 0x4 | 0xC | The low u16 indicates whether the system setup is required, such as when the system is booted for the first time or after doing a System Format: 0 = setup required, non-zero = no setup required |
0x00110001 | 0x8 | 0xC | TitleID of the menu to launch, used by NS on dev units (this block can be edited on dev units with Config) |
0x00120000 | 0x8 | 0xC | ? (read by HID) |
0x00130000 | 0x4 | 0xE | If response is 0x100 then debug mode is enabled. |
0x00150000 | 0x4 | 0xC | ? |
0x00150001 | 0x8 | 0xC | ? |
0x00150002 | 0x4 | 0xE | ? |
0x00160000 | 0x4 | 0xE | Unknown, first byte is used by config service-cmd 0x00070040. (Unknown whether the last 3-bytes are used) |
0x00170000 | 0x4 | 0xE | ? |
0x00180000 | 0x4 | 0xC | ? |
0x00180001 | 0x18 | 0xC | ? |
0x00190000 | 0x1 | 0xC | Unknown. NFC-module checks for value1/non-value1. |
The developer unit TID block only exists on developer units.
Stereo Display Settings
All values are hard-coded in cfg module.
Offset | Size | Value | Description |
---|---|---|---|
0x0 | 4 | 62.0f | assumed pupillary distance in mm? |
0x4 | 4 | 289.0f | assumed distance in mm between player's eyes and upper screen? |
0x8 | 4 | 76.80f | width in mm of (old) 3DS upper screen (doesn't vary for different models?) |
0xC | 4 | 46.08f | height in mm of (old) 3DS upper screen (doesn't vary for different models?) |
0x10 | 4 | 10.0f | |
0x14 | 4 | 5.0f | |
0x18 | 4 | 55.58f | |

0x000A0000 Block
Byte | Description |

0x0-0x13 | UTF-16 username, with no NULL-terminator. |
0x14-17 | Usually zero? |
0x18-0x1B | u32 NGWord version the username was last checked with. If this value is less than the u32 stored in the NGWord CFA "romfs:/version.dat", the system then checks the username string with the bad-word list CFA again, then updates this field with the value from the CFA |
LCD display config
There seems to be some sort of LCD display configuration stored in this cfg. When using the cfg-save from an Old3DS on a New3DS without formatting the cfg first, the bottom-screen display is somewhat off(which is fixed by formatting the cfg-save).
