Good news. The rumored Xbox 360 backward compatability list that leaked online earlier this week is now available on Xbox Live, according to Major Nelson. With this update, the backward compatability listing numbers over 300 original Xbox titles.

The better news? It even contains a title not originally listed in the leaked version, in the form of Conker Live and Reloaded.

Hit the jump for the full list of new and updated supported games, then cue bitching that Game X is sadly missing. Michael McWhertor
