Editing STAR Files

== Overview ==
STAR files 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].
