The Mcpx boot ROM image is not a mere BIOS file but a critical piece of silicon firmware that dictates the original Xbox’s lowest-level startup. In Xemu, accurate emulation of this 32 KB image requires a blend of ARC core recompilation, MMIO trapping, and timing approximation. Current limitations highlight the difficulty of emulating hybrid CPU/GPU boot sequences without original hardware documentation. Future work could focus on cycle-accurate ARC simulation or hardware-assisted tracing of genuine MCPX behavior. Mcpx Boot Rom Image Xemu
