XRoar - Dragon & CoCo emulator
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. More features.

The manual is available in these formats: PDF and HTML. See Getting started for a quick guide to running XRoar. See Building from source for instructions on building from source.
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.

Ron from DCEmu started a port to the Dreamcast called DragonDC. The last post about it I can find was from the 12th April 2007.
MESS, the "Multiple Emulator Super System", emulates a variety of old computer hardware, Dragon included. Source available.
T3 and PC-Dragon, two DOS-only emulators written by Paul Burgin. Source code is available for PC-Dragon, but redistribution of modified copies (of the source) is not permitted, amongst other restrictions. T3 is closed source.
Vcc, a Windows-only CoCo 3 emulator. Does not emulate CoCo 1/2 (beyond what compatibility a CoCo 3 had) or Dragon. Recently open-sourced (August 2015), though at time of writing there's no easy way to clone the entire project at once.
