Henrik RydgårdandClaude Opus 5 ddc673916d Tools/pkg.py: read PSP update packages, and notes on the format ...

A standalone Python reader for the .pkg containers Sony shipped PSP game
updates in: it prints a package's header, metadata, both PARAM.SFOs and its
item table, and extracts the payload. Nothing in PPSSPP calls it - it exists to
work the format out and to have a second implementation to check the C++ one
against, the way Tools/ already holds a few other one-off analysis scripts.

docs/pkg_notes.md is what it was written from: the header and item table
layout, the two AES-CTR keys a single package mixes, and the detail that trips
up a first attempt - which key applies is per item, not per package, so a
reader that picks one produces garbage filenames for most of a package while a
few entries decode perfectly.
