This project is focused on making significant forward progress in terms of features, performance, stability, and user experience in Xbox emulation. This project is an active fork of the XQEMU project, which is based on the very popular and highly actively maintained QEMU full system emulator project.

XQEMU Git Changelog
fpu: Begin using host FPU for hard x87 emulation
This is a start to hard float support for x87. It can fail in several
ways and has lots of room for improvement, but based on practical
testing it appears reliable and significantly increases performance in
FP-bottlenecked game code. Improvement to rounding, exception handling,
and performance accompanied by rigorous testing will be necessary next
steps for this work.
