Scratchpad Filesystem
BNA archives store files in folders that do not exist on the ROM.
For example, /root/bg3d/b3d_audition_a1_ill_wat.bna exctracts a file into the folder /root/bg3d/audition_a1/ but does not create this folder itself. /root/bg3d/audition_a1.bna does create this folder, indicating something in memory is keeping track of files.
File Formats Under Research
BXR Files (Bandai? Xbox? Resources)
| Entry | Size | Notes |
|---|---|---|
| Magic Header | 0x4 | "BXR0" |
| Unknown Data? | Varies with number of resources cataloged | Bulk of research to be done here |
| Resource Listing | Varies with number of resources cataloged | Plaintext, separated with 0x00 |
AIX Files (Audio? I???? X????)
Criware proprietary audio format. Seems to be an archive?
| Entry | Size | Notes |
|---|---|---|
| Magic Header | 0x4 | "AIXF" |
| Metadata Header? | 0x43? | Some kind of metadata for the file as a whole? |
| Subfiles Metadata Table | 0x17B3 | Table of data for subfiles. Each entry 0x10 bytes. If less than 0x17B files, remaining entries are zero filled. |
| Subfiles Headers? | 0x6A per subfile | "(c)CRIAIXP" + [HEADER DATA] + 0xFF 0xFF 0xFF 0xFF |
| Subfile Data | Varies | |
| Zero Filled Footer? | ???? | Unsure if part of final subfile or AIX |
NSH (Namco SHader)
"Stored" in /root/effect/ scratchpad file system, found in /root/initialTemp/initialTemp.bna. Appears to be mostly SM 3.0 DXBC.
| Offset | Entry | Size | Description |
|---|---|---|---|
| 0x0 | Magic | 0x4 | "NSXR" |
| 0x4 | File size | 0x4 | Size of the entire NSH |
| 0x8 | Number of Shaders in archive? | 0x1? | |
| 0x9 | Constant data? Number of combined VS/PS? | 0x7? | 0x00 0x00 0x01 0x00 0x00 0x00 0x00 |
| 0x10 | Unknown Header/Padding | 0x10 | |
| 0x20 | Unknown | 0x18 | Unknown header/DXBC |
| 0x38 | Size of DXBC/ucode? | 0x4 | Always equal to total file size - 32 byte NSH header |
| 0x3C | Unknown | 0x44 | Unknown header/DXBC |
| 0x80 | Offset Table | 0x80 (0x10 per entry) | Offsets from start of DXBC to various sections of DXBC
Each entry is composed of a DWORD offset from end of NSH header (ex - 0xE0 points to 0x100), an unknown DWORD, a length DWORD and a second unknown DWORD Currently known entries are Vertex Shaders, Pixel Shaders, Vertex Shader Globals and Pixel Shader Globals |
| 0x100 | Shader ucode | Varies | Compiled with XDK 4025. See Xbox 360/Hardware information/Xenos (GPU) for more info |
