XRoar is a Dragon emulator that runs on a wide variety of platforms. Due to hardware similarities, XRoar also emulates the Tandy Colour Computer (CoCo) models 1 & 2.


Some Features are:


  • Emulates Dragon 32, Dragon 64, Dragon 200-E, Tandy CoCo 1 & 2, and compatibles.
  • Emulates DragonDOS, Delta and RSDOS disk systems.
  • Emulates the Orchestra 90-CC stereo sound cartridge.
  • Supports both raw and translated keyboard modes.
  • Reads and writes virtual cassettes (compact '.cas' files and audio files).
  • Reads and writes VDK, JVC and DMK format virtual floppy diskettes.
  • Saves and loads machine snapshots.
  • Provides a GDB target for remote debugging.
  • Initial Glenside IDE support.


XRoar is easily built from source under Linux, and binary packages are provided for Windows. It should still be possible to build for Mac OS X, but no binary packages are currently being provided.


XRoar was originally written to run on Solaris, Linux and the GP32 handheld. Later, it was ported to the Nintendo DS. Support has now been dropped for the GP32 and NDS as emulation accuracy, and thus the CPU requirement, has increased. Builds have not been tested under Solaris for some while.
