If you want to play your old Xbox titles on your Xbox 360 console, you need to have the HDD-equipped Xbox 360 version, not the Core System version.
To play the 212 Xbox games on the Xbox360, one needs to download and install the emulation software on the Xbox 360 hard drive (available to Xbox live subscribers on Xbox.com).
If your game title’s not on the 212 list, you’re out of luck 🙂 BTW any Filipino gamers out there who have the 360 already?
