Editing STAR Files

== Overview ==
STAR files (file extension .star) store packages on the [[PSX Update Disc]] 2.11. It is a fairly simple archive format that is neither compressed nor encrypted. Each entry consists of the following segments:
* a header (size: 0x8 bytes)
* a file name (size 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 / (0x2F).

Unpacking is possible by using [https://github.com/Brawl345/stargazer Stargazer].

== Header structure ==
{| class="wikitable"
|- style="background-color: #ddd;"
! Start
! Length
! Description
|-
| 0x0
| 1
| Size of header + file name
|-
| 0x1
| 1
| Padding (always 0x00)
|-
| 0x2
| 4
| 32 bit file data size in byte (without file name or hash), max size per file is thus 4 GBytes minus 1 Byte
|-
| 0x6
| 1
| Size of file name in bytes, limited by the total size of header+name also being stored in a single byte
|-
| 0x7
| 1
| Padding (always 0x00)
