Playing Original Xbox Games on Xbox 360: Not Natively Possible—Here's How to Play Them Today

The Xbox 360 cannot play original Xbox discs. Backward compatibility was never implemented on 360 hardware.

Why

CPU: Original Xbox = Intel Pentium III (x86, 733 MHz). Xbox 360 = PowerPC Xenon (tri-core, 3.2 GHz). Different ISA.
GPU: NV2A (GeForce 3-class) vs. Xenos (Unified Shader, ATI). No instruction overlap.
OS: Xbox (custom Windows 2000 kernel) vs. 360 (hypervisor + Windows-derived).
Disc Format: Xbox = DVD-9 (custom layout). 360 = DVD-9 (different layout, security sector).
