Original Xbox games download - problems
Microsoft released a list of known issues with regards to the games (e.g. Halo, Fable etc) which will be available for downloand after the fall dashboad update. I had this experience with SW:KOTR which i played on the 360 emulator and had audio issues and more importantly severe slowdown/frame rate issues which made the game almost unplayable at the later stages of the game.
It is disgraceful for MS to make available to consumers products which are known to have such issues. Especially since at the 14Euros price you can find most xbox original games in mint condition on Ebay which gives you the option to play the game either on the 360 or on the original Xbox which will have no issues.
