Best suited to
People who want to run legally acquired original Xbox games on a Windows, macOS, or Linux computer and can prepare the required Xbox system files.
Look elsewhere if
Users seeking a turnkey emulator with no console-derived setup requirements, guaranteed compatibility, or split-screen play streamed over the internet, and should evaluate alternatives such as Cxbx-Reloaded instead.

Overview
xemu is a free, open-source emulator for the original Microsoft Xbox. The project began in 2020 as a continuation of XQEMU and is built on QEMU.
It runs on Windows, macOS, and Linux. Users need an OpenGL 4.0-compatible GPU, Xbox system files, and game images in xiso format. The project describes compatibility and performance as dependent on the game, emulator version, and host computer.

xemu Gotchas & Operational Limits
These are documented constraints or practical friction points that may matter before you adopt the product.
Game disc images must use the xiso format; ordinary ISO images may not work.
Users may need to prepare or convert their own game images before loading them.
Evidence source ↗The Linux Flatpak installation can write only to its designated data directory by default.
Users storing virtual hard disks elsewhere may need to grant additional directory access.
Evidence source ↗Xbox snapshots store machine state in the virtual hard-disk image and can affect which game saves appear after restoring an older snapshot.
Snapshot rollback can make later in-game save changes absent from the restored machine state.
