What xemu is

xemu is free, open-source software that emulates the original Microsoft Xbox on Linux, macOS and Windows desktops. It recreates the console hardware at a low level for official titles and homebrew applications. Games can be scaled from 480p to 1080p, and snapshots save or restore the full machine state, including the disc, controllers and hard drive. The emulator supports virtually all gamepads and up to four controllers, while emulating the Xbox controller. Networking offers NAT, UDP Tunnel and Bridged Adapter modes for connections to other xemu instances or real Xboxes locally or over the Internet. Documentation also describes Xlink Kai and free xemu servers for multiplayer. Users must acquire an MCPX boot ROM, BIOS and hard disk image themselves. An unmodified retail BIOS cannot currently boot games because required DRM functions are unimplemented; a debug or modified retail BIOS is needed. An OpenGL 4.0-compatible GPU is required, and performance varies by host system.
