Overview
STAR files store packages on the PSX Update Disc 2.11. It is a fairly simple archive format. Each entry consists of the following segments:
- a header (size: 0x8 bytes)
- a file name (size is specified in header)
- the actual file data (size specified in header)
- sha-1 hash of file data (size: 0x14 bytes)
Subfolders are handled by simply writing out the full path in the file name, with subfolders being separated with /.
Header structure
| Start | Length | Description |

| 0x1 | 1 | Padding (always 0x00) |
| 0x2 | 4 | 32 bit file data size (without file name or hash) |
| 0x6 | 1 | Size of file name |
