Clarification: "Xbox Arcade" was not a console. It was a digital distribution service on the original Xbox (2001–2005) called Xbox Live Arcade.
| Console | Store | Backward Compatibility |
|---|---|---|
| Xbox 360 | Xbox 360 Marketplace (still up) | Plays original Xbox games (disc) + 360 digital |
| Xbox One | Microsoft Store | Plays select 360/original Xbox digital (BC program) |
| Xbox Series X|S | Microsoft Store | Best BC: thousands of 360/original titles, auto-HDR, FPS boost |
If you have an original Xbox (the big black box), it is offline only. No new games, no downloads. For digital libraries, you need a 360 or newer.
