An official list of Xbox games that are playable with the upcoming Xbox 360 has been released. The compatibility is achieved with an emulator software that must be acquired from Xbox Live, Xbox.com or the postal system. The device however comes with an early version of the emulator to be used with hit games Halo and Halo 2. Todd Holmdal is answering questions regarding the emulation at Xbox.com.

Xbox.com: How is your backward compatibility solution going to work?

Todd: As you’ve heard from us before, backward compatibility on Xbox 360 is done through software. Now that we’ve solved the technical challenge and the emulator is working, we’re certifying each original Xbox title by hand to run on Xbox 360.

What I’m really proud to tell you and your readers is that it’s easy to get the emulation software, and it’s free. We’ll give gamers a choice—you can get the latest software updates from Xbox Live, burn a CD from xbox.com or sign up on Xbox.com for a CD that can be delivered to your home at a nominal shipping and handling fee. Once you get the CD, put it in your Xbox 360 and you’re ready to go.

Xbox.com: Will there be any benefits to playing original Xbox games on my Xbox 360 console?

Todd: Absolutely. One of the great things about gaming on Xbox 360 is the satisfaction of knowing that every game will be playable in high definition. We are now proud to reveal that this extends to the original Xbox games as well. Every original Xbox game will be upscaled to 720p and 1080i, and will take advantage of Xbox 360’s anti-aliasing capabilities, delivering a picture that is clearer and crisper than anything available on Xbox.
