XRoar is a free emulator for Dragon, Tandy Colour Computer, Tandy MC-10, and related 8-bit systems. Supported machines include Dragon 32/64/200-E, Tandy CoCo 1/2/3, MC-10, and Matra & Hachette Alice 4K. It runs on Android, Linux, macOS, and Windows, with XRoar Online available in a browser. The emulator reads and writes cassette, floppy disk, and block-device images, and supports machine snapshots. Emulated hardware includes floppy controllers, sound cartridges, Glenside IDE, and several RAM expansions. Video options include PAL or NTSC emulation and composite video simulation, with multiple sound drivers. A GDB remote target supports interactive debugging, though 6803 debugging is not implemented. The Becker port can communicate with pyDriveWire or Drivewire 4. In the browser version, users can fetch cassette, floppy, and hard disk images from the web or upload local files, but its sandbox keeps accessed files temporarily in memory rather than working transparently with local files. Firmware ROM images are required for useful emulation, and floppy write-back is enabled by default. XRoar is GPL version 3 or later software and comes without warranty.
