NAND structure
Boot Partitions
Boot Partition 0 (0 of 1)
Offset | Size | Description |
---|---|---|
0x000000 | Title 0100000000000819 BCT | |
0x004000 | Title 010000000000081A BCT | |
0x008000 | Title 0100000000000819 BCT | |
0x00C000 | Title 010000000000081A BCT | |
0x100000 | Title 0100000000000819 "package1" | |
0x140000 | Title 0100000000000819 "package1" (Backup) | |
0x180000 | Keyblob area, the first 0xB0 is identical to the console-unique "customer data" section in BCTs | |
0x184000 | Unknown, 0x20-bytes hash + one u64? All zero on 1.0. |
Boot Partition 1 (1 of 1)
Offset | Size | Description |
---|---|---|
0x000000 | Title 010000000000081A "package1" | |
0x040000 | Title 010000000000081A "package1" (Backup) |
User Partitions
Partition name | Offset | Size | Bis Partition ID | Description |
---|---|---|---|---|
N/A | 0x0 | 20 | GPT header, Bis-storage also allows raw access to the entire NAND eMMC sectors starting at sector0. | |
PRODINFO | 0x00004400 | 0x003FBC00 | 27 | "CAL0" raw partition containing set:cal data |
PRODINFOF | 0x00400000 | 0x00400000 | 28 | FAT12 filesystem, additional calibration? |
BCPKG2-1-Normal-Main | 0x00800000 | 0x00800000 | 21 | For all these packages, data starts at offset 0x4000 and is not console-unique. This is installed from "package2": on retail it's from FIRM-A 0100000000000819, for unknown cases it's from FIRM-C, 010000000000081B. |
BCPKG2-2-Normal-Sub | 0x01000000 | 0x00800000 | 22 | Identical to BCPKG2-1-Normal-Main, probably used as a backup partition. |
BCPKG2-3-SafeMode-Main | 0x01800000 | 0x00800000 | 23 | This is installed from "package2" in firmware package B, 010000000000081A. |
BCPKG2-4-SafeMode-Sub | 0x02000000 | 0x00800000 | 24 | Identical to BCPKG2-3-SafeMode-Main. |
BCPKG2-5-Repair-Main | 0x02800000 | 0x00800000 | 25 | Unknown what title this originates from. |
BCPKG2-6-Repair-Sub | 0x03000000 | 0x00800000 | 26 | Identical to BCPKG2-5-Repair-Main. |
SAFE | 0x03800000 | 0x04000000 | 29 | FAT32 filesystem |
SYSTEM | 0x07800000 | 0xA0000000 | 31 (and 32?(Error 0x2EE202 is returned for 32)) | FAT32 filesystem |
USER | 0xA7800000 | 0x680000000 | 30 | FAT32 filesystem |
0x747BFFE00 | 0x200 | This is the backup GPT header specified by the main GPT header. This is also the last sector readable with Bis-storage paritionID 20. |
NCAs stored in NAND are raw, identical to the data readable with Content_Manager_services#ReadEntryRaw.

The saves for all non-system applications, regardless of where the application is located(storageID), is stored here. Each user account which has savedata has a separate saveimage. Save-common for an application is presumably a separate saveimage too. Every saveimage here is only for applications.

On a v2.1 system with MountBis, the only thing under here is "PRF2SAFE.RCV".
