UpdateList

Update lists are files which tell the updater about patches and the changed/included files and metadata about those.

You can't read update lists right away, as they are encrypted using XTEA and the region-specific key, but once they are decrypted, they are a simple XML format.

A simple but invalid XML format, as it includes multiple root nodes, so conventional XML parsers will refuse to interpret it.

File Format
