Has anyone tried to reverse Need for Speed: Undercover BINs BUNs and LZCs? GEOMETRY.BIN and LZCs have custom compression. I would like to request to start a new tool that decompresses GEOMETRY.BIN and LZCs and new plugin to import GEOMETRY.BIN. Game is powered by EAGL.

Samples:

Using Aluigi's script on that vpa file gives another 219 extracted files.
