MSBP (File Format)
Revision as of 13:29, 5 November 2018 by Shibboleet (talk | contribs) (Fix some stuff, add label entry structure.)
The purpose of MSBP (MeSsage Binary Project) isn't fully known, but it is known that this file is related to colors, some text flow, and other attributes. Every section is aligned to the 0x10th byte with 0xAB.
Header
| Offset | Type | Description |
|---|---|---|
| 0x00 | String | File magic. Always "MsgPrjBn" in ASCII. |
| 0x08 | UInt16 | Byte Order Mark (BOM): 0xFEFF for big endian and 0xFFFE for little endian. |
| 0x0A | UInt32 | Version. Always 0x40000000. If this is the Wii MSBP, 0x30000000 |
| 0x0E | UInt16 | Number of sections. |
| 0x10 | UInt64 | Filesize. |
| 0x18 | UInt64 | Padding. |
| 0x20 | End of header. |
CLR1
Seems to stand for "color".
| Offset | Type | Description |
|---|---|---|
| 0x00 | String | Section magic. Always "CLR1" in ASCII. |
| 0x04 | UInt32 | Section size. The first 0x10 bytes of this section and the alignment are not counted towards this size. |
| 0x08 | UInt64 | Padding. |
| 0x10 | UInt32 | Number of colors. |
| 0x14 | End of header. |
Directly after the number of colors, there are N amount of RGBA colors (defined by the count).
CLB1
This section links a color entry in the above section to a label.
| Offset | Type | Description |
|---|---|---|
| 0x00 | String | Section magic. Always "CLB1" in ASCII. |
| 0x04 | UInt32 | Section size. The first 0x10 bytes of this section and the alignment are not counted towards this size. |
| 0x08 | UInt64 | Padding. |
| 0x10 | UInt32 | Number of labels. |
| 0x14 | End of header. |
Right after the header, the actual label entries are defined.
| Offset | Type | Description |
|---|---|---|
| 0x00 | Byte | String length. |
| 0x01 | Byte[N] | Label name, where N is the string length. |
| 0x01 + N | UInt32 | Index of the color that is assigned to this label. |
| 0x01 + N + 0x04 | End of label entry. |
