all can but most you need to manually update your Xbox the halo games and be played on Xbox 360
No the Xbox 360 Is compatible with some Original Xbox Games although Can not be played online as there was an update because Microsoft wanted more people to get the xbox 360
No games will update your Xbox 360. When you insert a game and it asks you to update, this is a game update.
In order to play games for the original Xbox on the Xbox 360 you will need to have the hard drive. This is because the update is downloaded onto it.
No they do not, but you can play certain Xbox original games on Xbox 360
You can not play xbox 360 games on an original xbox, however you can play some original xbox games on an xbox 360 console.
Yes, an xbox 360 Premium can play SOME original xbox games, though often an update is necessary to run the game, and the xbox live guide does not run in original xbox games. In the event that there is no update to allow that particular game to run, you may not be able to play it on 360. But, many lesser known obscure games can still be played on the 360. The games that most often aren't playable on 360 often either have an xbox 360 version and hence the developers didn't allow it, or it has a sequel for the 360 and would've defeated the purpose of bringing that franchise to the 360.

No, you cannot. The "Original" Xbox cannot play Xbox 360 games. However, a list of "original" Xbox games are playable on the 360.
Answer:Only a select few or original Xbox games are playable on Xbox Live with and Xbox 360. The popular original Xbox games (i.e. Halo 2) are playable. The Xbox must be updated first before it plays any original Xbox game. This will happen when the disc is inserted.When it says "the disc is inserted", it means that you get a disc that has what is called a backward-compatibility update, which is the update that allows you to play said Original Xbox Games. To get this update you must download it via disc (OXM Magazine game disc O burned disc from the official Xbox website) or the Xbox Live Marketplace, but I'm not sure they have it on the marketplace.M3NARD3C0Y:A list of backward compatible games: http://www.xbox.com/enUS/games/backwardcompatibilitygameslist.htmWhen inserting an Xbox game to the Xbox 360 console, it will ask to download an update for the game so it can be playable. Games not available in the list are not compatible. You must have Xbox LIVE to download the update. After all that, you can play Xbox LIVE. You can use your current Xbox LIVE Gamertag from your Xbox 360 or you can recover your gamertag from your original Xbox to your Xbox 360. It would then be converted to the newly update Xbox LIVE and possibly get a free 1 Month Gold Subscription. It's what I did :) some games may be played but not any of the halos if they are an original xbox gameAnswer:While the following was true (I don't have the heart to delete this guy's answer), the Xbox 360 no longer supports original Xbox games on Xbox LIVE.
