Yes it can. With the exception of the new Xbox 360 250 GB model, all Xbox 360 HDDs are compatible with every system.
No, the new xbox 360 slim basically has a hard drive like a block, way better than the original xbox 360's long hard drive.
No you will need a transfer cable to get your memory on a new xbox. Alternatively you can configure an USB flash drive and use that as your memory system
Yes, the Xbox slim is only a smaller Xbox 360 with a couple of improvements. It is NOT a new generation of console, it is just like a sequal to a movie.
Yes, it will. To get the HD quality you will need component cables.
If you count a router cable as a ethernet cable, yes. An ethernet cable is what you plug from your xbox into a laptop/router/modem to connect to xbox live. The following SKU's come with ethernet cables. *Xbox 360 PRO *Xbox 360S *Xbox 360 Elite The xbox 360 CORE and ARCADE have no ethernet cables. Hope this helped.
Yes both games were made for the original Xbox console but the new Xbox 360 Console is backwards compatible and allows you to play original games. However, you'll be restricted from the Xbox LIVE Guide, Parties, Private Chat, etc. while playing original Xbox games on the 360.
If you mean play xbox 360 games on the original xbox then no. If you mean play ORIGINAL xbox games on the 360 then yes. Some games work straight away when you put them in the 360 but some you have to download something off live so it does work i think.
No, you cannot use an external hard drive on the Xbox 360 to play original Xbox games like Halo 2. The Xbox 360 is backwards compatible with select original Xbox titles, but these games must be installed on the console's internal hard drive or a compatible Xbox 360 hard drive. An external hard drive can be used for storing Xbox 360 games and data, but it won't support original Xbox game playback.
No, the Xbox 360 Arcade cannot use the new Kinect that was released in November. The Kinect requires a dedicated power supply and specific hardware capabilities that the Arcade model lacks. Only the Xbox 360 S and later models are fully compatible with Kinect.
yes they can on another or new xbox 360
New games do work on an Xbox 360. This is, of course, as long as they are specifically Xbox 360 games.
