The MgrTbl.dat File
When LRF files are transferred onto a memory stick using the LIBRIe Reader software, a certain file structure is created. Part of this structure is the MgrTbl.dat file (located in the /mssony/librie/booklist directory on the memory stick). This file acts as a list of the books contained on the memory stick. Linux users can also create the MgrTbl.dat file using BookListGen[1]
Format of MgrTbl.dat File
The MgrTbl.dat file consists of individual records one after another (i.e. There is no header at the start of the file, and there is nothing inbetween the records). Each of the records describes a single LRF file.
Format of Record
Each record consists of a 33 byte header followed by data fields.
Header
The header describes the lengths of various fields in the record. It starts at offset 0x00 and is 33 bytes long. All values are in Intel (LSB first) order.
| Offset (hex) | Size(bytes) | Name | Description | Example value |
| 0x00 | 2 | RecordLength | Length of the entire record | D8 06 |
| 0x02 | 2 | TitleLength | Length of the Title field | 0C 00 |
| 0x04 | 2 | unknown | unknown | 00 00 |
| 0x06 | 2 | AuthorLength | Length of the Author field | 2C 00 |
| 0x08 | 2 | unknown | unknown | 00 00 |
| 0x0A | 2 | MysteryBytes1Length? | Length of MysteryBytes1? | 0A 00 |
| 0x0C | 2 | LocationLength | Length of the LRF location | 27 00 |
| 0x0E | 2 | GIFDataLength | Length of the GIF thumbnail data | FA 05 |
| 0x10 | 2 | unknown | unknown | 60 00 |
| 0x12 | 15 | unknown | unknown (padding?) | zeros |
Data Fields
After the header, the following data fields are found, starting at offset 0x21:
| Name | Size (bytes) | Format | Description | Example value |
| ID | 32 | UTF-16 | The ID of the book | TESTBOOKID000004 |
| CreationDate | 15 | ASCII | The creation date of the book | 2004-10-26 |
| Title | Offset 0x02 in header | UTF-16 | The title of the book | The Lost World |
| Author | Offset 0x06 in header | UTF-16 | The author of the book | Sir Arthur Conan Doyle |
| MysteryBytes1? | Offset 0x0A in header | UTF-16 | unknown | Aleph |
| Location | Offset 0x0C in header | ASCII | Location of LRF file (preceded by a:) | a:/EBOOK/BBEB/TESTBOOKID000004.lrf |
| MysteryBytes2 | 21 | unknown | Binary | See Below |
| GIFData | Offset 0x0E in header | Binary | GIF thumbnail image data | N/A |
In the sample file MysteryBytes2 was set to the following:
C0 25 0D 00 00 00 00 00 3D 55 81 41 00 00 01 00 00 00 00 00 14
The meaning of this sequence has yet to be determined.
