However, performance is heavily CPU-dependent due to the single-threaded nature of the original hardware. Dual-core CPUs can struggle, while modern quad-core and higher processors generally handle the load with ease.

The original Microsoft Xbox (2001) presents unique challenges for emulation due to its hybrid x86 architecture and custom NV2A graphics chipset. Unlike consoles based on standard PC hardware, the Xbox requires "low-level" emulation (LLE) to replicate the intricate timing dependencies and undocumented hardware behaviors. This paper examines Xemu , an open-source emulator that prioritizes accuracy over performance. We discuss its internal architecture, including dynamic recompilation (Dynarec), reverse-engineering of the NVIDIA NV2A GPU, and the challenges of emulating the proprietary BIOS. The paper concludes that Xemu serves as a critical tool for both playing Xbox titles on modern systems and preserving the console's software library for future generations. However, performance is heavily CPU-dependent due to the
