1.0.1

xzptool is a command-line utility that can decompress .xz_ compressed blobs into .xzp archives, and vice versa.

In the Xbox port of Half-Life 2, since the game was large they needed to compress their custom archive format, XZP. They used JCALG1 compression to create a custom compression format, and when the game booted it would extract the archives from the compressed blobs stored on the DVD to the Xbox's hard drive.

This utility is a cleanroom recreation of the xcompress tool, which was never publicly shipped. Rather than perfectly replicate Valve's interface, it performs the appropriate action depending on the input, allowing the user to simply drag .xz_ and/or .xzp files on top of it.
