File Header

OFFSET SIZE DESCRIPTION (common value)
0x00 4 Magic ("0TIP")
0x04 4 UNKNOWN ("_1""00" LE, maybe number of first folder or max number of photos per folder)
0x08 2 Block-Size (0x0BB8 => 3000 Bytes)
0x0A 2 # folders' hundreds digit
0x0C 2 # folders' tens digit
0x0E 2 higher number of photos reached in the last folder (i.e. : next photo's number will be this number+1)
0x10 2 UNKNOWN (0x0000)
0x12 2 # of frames
0x14 2 CRC16 of whole file
0x16 2 Size of header (0x0018)

It is known that if the offset to entries (size of header) is pushed passed the end of the file, the system freezes, it is not known wether this is exploitable or not. Infact any change which makes it read passed the end of the file makes it crash.

Each entry (16 bytes)

4 : Date 
8 : Zeroes
1 : Type (1: Frame, 3: Photo)
1 : UNKNOWN : 8 * n <-- n is may entry number (first = 0 seconds = 1 ...) only the last Byte of the result is used
1 : Sticker (0: None, 4: Star,  8: Clover, 12: Heart, 16: Frame)
1 : UNKNOWN : Always zero

Misc information

  • SD:\DCIM\100NIN01
  • SD:\DCIM\100NIN02

Frames are stored in:
