That headline is probably the nicest way to say that it won't be smooth sailing when Xbox Originals drops with the 360's Fall dashboard update. Microsoft has set aside a little page to discuss the "known issues" of the service, which will allow users to download and play Xbox 1 games on their Xbox 360s. The issues range from minor framerate drops, to graphical and sound glitches, to un-supported resolutions, but most problems differ from title to title.

Universally, all Xbox Original titles will present with some choppyness during publisher logos as the games are cached into memory. Additional content like demos and trailers in games are unsupported by the service, and selecting them in an Xbox Originals title (such as Fable, Crimson Skies, and Fuzion Frenzy), will crash the system and require a restart of the console.

Issues like these make the entire service seem a lot less elegant, particularly with options in games that players will have to know not to select. Still, these things are bound to happen when a company tries to force-feed last-gen software to next-gen hardware. Users will be able to choose whether or not the slightly-less-than-perfect Xbox Originals will be worth the 1200 Microsoft Points each come December 4.
