File header:
00000-00007: Header 1UJQ00_1
00008-0000B: Number of pictures plus 1 (why?)
0000C-00011: Unknown value (seems to be static?) B80B01000000
00012-00013: Total number of photos (excluding 2D dups)
00014-00017: Appears to be file size. It's only 32 bits = 4GB max. A few hundred K
larger than the actual size of every file in DCIM (?)
1607971 vs DCIM/100NIN = 1441792 vs DCIM = 147560 vs files = 1409024
vs non-disk usage = 1224857
phtcache non-disk = 456024, disk = 458752
phtcache (non) + files (non) = 1680881 - 1607971 = 72910 = 72K hmm...
maybe the 72910 is some kind of checksum?
( I have no clue, all these notes were probably worthless)
From 0x0018, one block per picture. Each block is 0x98 bytes long and formatted as such:
00000-00003: Preferred image file format. Should be MPO\x00 or JPG\x00. The inner cam is the only
one that will yield JPG. 3D pictures are taken even with screen switched to 2D.
00004-0000B: Name of image
0000C-00013: Subfolder of image
00014-0001B: Time taken based on "DS epoch" (start of 1/1/2000) (UNIX+946684800)
0001C-00023: Time last viewed?
