Are Original Xbox Games Compatible with Xbox 360?

No physical Xbox discs work on Xbox 360. Different CPU (x86 vs. PowerPC), GPU, OS, and disc format (DVD‑ROM vs. DVD‑9).

How to Play Xbox Games on 360

• Xbox Originals (Xbox Live Marketplace): ~50 titles digitally re‑released (e.g., Halo, Fable, Psychonauts, Ninja Gaiden Black). Purchased on 360 Marketplace (now delisted—buy via Xbox.com on PC).
• Backward Compatibility on Xbox One/Series X|S: Hundreds of Xbox & 360 games play natively via emulation—best way today.

To play original Xbox discs, you need an **original Xbox console**.
