Dragon 32

Emulate the Dragon 32/64 home computer with Linux

Emulation is the practice of using a program (called an emulator) on a PC to mimic the behaviour of a home computer or a video game console, in order to play (usually retro) games on a computer.

Home computers were a class of microcomputers that entered the market in 1977 and became common during the 1980s. They were marketed to consumers as affordable and accessible computers that, for the first time, were intended for the use of a single non-technical user.

Back in the 1980s, home computers came to the forefront of teenagers’ minds. Specifically, the Amiga, ZX Spectrum, and Atari ST were extremely popular. They were hugely popular home computers targeted heavily towards games, but they also ran other types of software.

The Dragon 32 and Dragon 64 are home computers based on the Motorola 0.89 MHz 6809E processor and 32 and 64 KB of RAM respectively. The Dragon 32 was made from 1982 to 1984. The Dragons are very similar to the TRS-80 Color Computer (CoCo), and were produced for the European market by Dragon Data, Ltd., in Port Talbot, Wales, and for the US market by Tano of New Orleans, Louisiana.

The machines were not big commercial successes in part because they had flaws both in the home computer market and the educational market. For example, while the Dragon machine sported a full-size keyboard that was tactile, it could only display uppercase characters effectively ruling itself out of the educational market immediately.

Dragon ROMs

The firmware ROM for both the Dragon 32 and Dragon 64 are under copyright. If you own a machine, you can dump your own ROM. If you have difficulty extracting these from your actuals Dragon or CoCo, dumps may be available from the Dragon Archive or the Color Computer Archive. The Dragon Archive has a wealth of useful information and materials.

Dragon 32 BASIC is provided by Microsoft and shares many features found on other home computers of its era.

Dragon Emulators

XRoarOur recommended emulator is XRoar, which can emulate Dragon 32 and Tandy Color modes 1 & 2 computers. It offers a good range of features including support for joysticks, accelerated OpenGL output, support for all video modes, and much more.

Download the latest release of the source code from the project’s website. Extract that file, change into the directory and compile the source code:

$ gzip -dc xroar-0.36.2.tar.gz | tar xvf -
$ cd xroar-0.36.2
$ ./configure
$ make
$ sudo make install

The project also provides an online emulator which you can use from a web browser. XRoar online can emulate all models of Dragon machines (32, 64, Tano Dragon, Dragon 200-E) and models of Tandy’s Color Computer (CoCo). The Tano Dragon is the US version of the Dragon 64.

The best alternative to XRoar is MAME, which also supports a huge range of portable and console gaming systems.

Dragon Software

Initially, the Dragon was reasonably well supported by the large UK software companies. Top-selling games available for the Dragon include Arcadia (Imagine), Chuckie Egg (A&F), Manic Miner and sequel Jet Set Willy (Software Projects), Hunchback (Ocean) and Football Manager (Addictive). Due to the basic graphics modes of the Dragon, converted games had a distinctive appearance, with colour games being usually played on a green or white background (rather than the more common black on other systems) or games with high-definition graphics having to run in monochrome.

We recommend you visit the Dragon Archive as it hosts over 700 files in its software archive.
