User Partitions

Partition name	Offset	Size	Bis Partition ID	Description
N/A	0x0	?	20	GPT header, partition ID also provides raw access to all partitions
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?)	FAT32 filesystem
USER	0xA7800000	0x680000000	30	FAT32 filesystem
