Xbox 360 games are built for the **PowerPC (Xenon) tri-core CPU**, a custom ATI Xenos GPU, and a proprietary OS/DRM stack. They **do not run natively** on PlayStation, Nintendo Switch, or standard x86 PCs.
For the authentic, hassle-free experience, a used **Xbox 360 S/E** ($60–$100) remains the most reliable way to play the full library.
