XRoar

What XRoar is

XRoar is a free emulator for Dragon, Tandy Colour Computer, Tandy MC-10, and similar 8-bit computers. Supported systems include Dragon 32/64/200-E, Tandy CoCo 1/2/3, MC-10, and Matra & Hachette Alice 4K. It is available for Android, Linux, macOS, and Windows, with XRoar Online providing a browser option. The emulator reads and writes cassette, floppy disk, and block device images, and supports machine snapshots. Its emulated hardware includes floppy controllers, sound cartridges, Glenside IDE, and several RAM expansions. Video features include PAL or NTSC emulation and composite video simulation, alongside multiple sound drivers. A GDB remote target supports interactive debugging, though 6803 debugging is not implemented. The Becker port supports communication with pyDriveWire or Drivewire 4. XRoar Online can fetch disk or cassette images from the web or accept local uploads, but its sandbox keeps files temporarily in memory rather than working transparently with local files. Firmware ROM images are required for useful emulation. Floppy write-back is enabled by default, so changes may overwrite an image when ejected or when XRoar quits. It is GPL version 3 or later software and comes without warranty.
