XRoar - Dragon & CoCo emulator

Skip to site navigation

XRoar is a Dragon emulator for Linux, Unix, Mac OS X and Windows. Due to hardware similarities, XRoar also emulates the Tandy Colour Computer (CoCo) models 1 & 2. Feature list.

These are the latest packaged builds. For old versions, see the file archive. The latest source code is version 0.32, released 2014-04-22.

The manual is available in various forms: PDF, HTML and plain text. See Getting started for a quick guide to running XRoar.

Firmware ROM images are required to usefully run this emulator. If you have difficulty extracting these from your real Dragon or CoCo, dumps may be available from the Dragon Archive.

Want a Dragon in your browser? Here's a limited but functional Flash version of XRoar. Needs Flash 10 and a pretty fast computer.
