BNBSHPK (Binary NX Bezel SHader PacKage) is an archive format used to store BFSHA files.
File Format
The file starts with the following header:
| Offset |
Type |
Description
|
| 0x00 |
Char[8] |
File magic. Always BEZSHAPK in ASCII.
|
| 0x08 |
UInt32 |
Version number.
|
| 0x0C |
UInt16 |
Byte-order-mark. FE FF for big endian, FF FE for little endian.
|
| 0x0E |
Byte |
Alignment shift. 2 raised by this value is the alignment required by this file when loaded into memory.
|
| 0x0F |
Byte |
Target address size. Size of a pointer in bits. Never set and there remains 0.
|
| 0x10 |
UInt32 |
Dummy value.
|
| 0x14 |
UInt16 |
A flag which is only used on runtime. One bit sets wether the file is relocated.
|
| 0x16 |
UInt16 |
Offset to the first section.
|
| 0x18 |
UInt32 |
Relocation table offset.
|
| 0x1C |
UInt32 |
Size of the file in bytes.
|
| 0x20 |
Int64 |
File entry array offset.
|
| 0x28 |
UInt32 |
Number of file entries in this archive.
|
| 0x3C |
Byte[4] |
Padding?
|
File Entry
| Offset |
Type |
Description
|
| 0x00 |
Int64 |
BFSHA file data offset.
|
| 0x08 |
? |
More data? It is currently unknown how this structure looks since the only file seen only has one file entry.

String Table
The string table is a table where all strings are stored. Each string has first the length written, which is a 16-bit integer, and then the string is stored as a null-terminated string. The string length does not include the null byte, and the 16-bit string length value is always aligned by 2. The string sorting algorithm is unknown.
| Offset |
Type |
Description
|
| 0x00 |
Char[4] |
Section magic. Always _STR in ASCII.
|
| 0x04 |
UInt32 |
Next section offset.
|
| 0x08 |
UInt32 |
Size of this section in bytes.
|
| 0x0C |
Byte[4] |
Reserved.
|
| 0x10 |
Int32 |
Number of strings stored in the string table. The first string is always an empty string ("") and is not included in this count.
