Title: The Ghost in the Boot ROM
A Note on Versioning
The “1.0” in xemu mcpx-1.0.bin is critical. Microsoft released several hardware revisions of the original Xbox (1.0 through 1.6). Each revision has subtle differences in its MCPX boot ROM—timing tweaks, bug fixes, and even changed cryptographic keys. If you try to use an MCPX dump from a 1.6 Xbox with a game that expects 1.0 behavior, XEMU may crash or fail to boot. For maximum compatibility, the 1.0 ROM is preferred because it represents the earliest, most “vanilla” hardware target. xemu mcpx-1.0.bin
