0x00090000 | 0x8 | 0x2? | This contains a u64 ID, used by processes using NWMUDS:Initialize. The first word is the same as LocalFriendCodeSeed, while the latter is a separate random word |
0x00090001 | 0x8 | 0xE | This console-unique u64 used by GenHashConsoleUnique is generated with the LocalFriendCodeSeed and with random data |
0x000A0000 | 0x1C | 0xE | Username |
0x000A0002 | 0x1 | 0xA | Language |
0x000B0000 | 0x4 | 0x8 | CountryInfo |
0x000B0001 | 0x800 | 0x2? | Country name in UTF-16, every 0x80-bytes is an entry for each language(not all entries are set) |
0x000B0002 | 0x800 | 0x2? | State name in UTF-16, every 0x80-bytes is an entry for each language |

0x000F0000 | 0x10 | 0x8? | 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 |
0x000F0004 | 0x4 | 0x8? | The first u8 is the System-Model value, the last 3-bytes are unknown |
0x00110000 | 0x4 | ? | 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 | 0xA? | TitleID of the menu to launch, used by NS on dev units (this block can be edited on dev units with Config) |
0x00130000 | 0x4 | ? | If response is 0x100 then debug mode is enabled. |
0x00160000 | 0x4 | 0x8? | Unknown, first byte is used by config service-cmd 0x00070040. (Unknown whether the last 3-bytes are used) |
