OverviewEdit
MPO = Multi-Picture Object
Document describing the file format used in mpo files: http://www.cipa.jp/std/documents/e/DC-007_E.pdf
Nintendo uses a common format for its 3D pictures. MPO is basically two JPG files concatenated in one file. The two JPG files has an EXIF data structure in their headers (This was developed by CIPA).
EXIF is a standard that specifies the formats for images, sound, and ancillary tags used by digital cameras (including smartphones), scanners and other systems handling image and sound files recorded by digital cameras.[1]
Nintendo's EXIF Data StructureEdit

Nintendo's EXIF MakerNote TagEdit
This still need to be figured out:
The MakerNote is made with Tiff Exif information (Big Endian)
first 2 bytes are the IFD Count (IFD is a 12 byte tag), Regulary there are 2 IFDs.
IFD structure
Tag | Type | Count/Value | Value/Offset |
---|---|---|---|
2 bytes | 2 bytes | 4 bytes | 4 bytes |
Nintendo's IFDs
Tag | Desc | Type | Count/Value | Value/Offset |
---|---|---|---|---|
0x1100 | Software-specific data | 7-Undefined | Count | Count=1 ? Value : Offset |
0x1101 | Nintendo 64byte Note | 7-Undefined | Count | Offset |
After the IFDs comes a 4 byte Zero ( {0,0,0,0} ).
And then the Data the IFDs point at (if at all)
Nintendo's 64Byte Note
Different from the wrapping structure this structure is Little-Endian.
Offset | Description | Type | Default Value |
---|---|---|---|
0x00 | Magic | char[4] | {'3','D','S','1'} |
0x04 | ? | uint32 | 1 / 2 / 4 / 5 |
0x08 | Timestamp | uint32 | Number of seconds since 1/1/2000 00:00:00 |
0x0C | Padding | uint32 | 0 |
0x10 | Title ID Low | uint32 | like the title id low but without the last two letters |
0x14 | Flags | uint32 | |
0x18 | Console ID | byte[4] | unique identifier |
0x1C | Padding | byte[12] | 0 |
0x28 | 3D Parallax | float | [-52,54] |
0x2C | Padding | uint32 | 0 |
0x30 | Category | uint16 | 0x2000 for a man, 0x4000 a woman, 0x1000 a mii... |
0x32 | Filter | uint16 | |
0x34 | Padding | byte[12] | 0 |
