What xemu is
xemu is free, open-source software that emulates the original Microsoft Xbox on Windows, macOS, and Linux desktop systems. It emulates the console hardware at a low level and is intended for official Xbox titles and homebrew applications. Games can be scaled from 480p to 1080p while running. Snapshots save or restore the complete machine state, including the loaded disc, attached controllers, and hard drive state. xemu 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. Running it requires users to acquire an MCPX boot ROM image, BIOS image, and hard disk image. An unmodified retail BIOS cannot currently boot games; a debug BIOS or modified retail BIOS is required. An OpenGL 4.0-compatible GPU is required.
