Woo! The latest Xbox 360 backwards-compatibility update is out, and one of my all-time favorite Xbox games now works, Guilty Gear X2#Reload!!! Also, I'll now be able to play Full Spectrum Warrior: Ten Hammers, Magic: The Gathering - Battleground, and Mechassault 2: Lone Wolf. Ironically, the Magic game is the only one of those that I actually have -here- with me.
The current backwards-compatible list can be found at:

Also, I've decided that when I get back home, the original Xbox will be made into a media-extender, either with Microsoft's official kit, or the open-source Xbox Media Center firmware (which sounds more versatile, and exciting to install).
