XROAR (AMIGA)
-------------
XRoar is an emulator for the Dragon
and Tandy range of computers. The
Dragon and Tandy are eight bit home
computers based on the 6809 CPU.
Initially produced in Wales in early
1980s, later it spawned some variants
in other countries as well. Even if
using a very powerful processor - the
eight bit smaller brother of the
Motorola highly successful 16/32 bit
68000 and 68008 family, the lack of
good peripherals, non quality software
and weak user base, made the computer
unpopular despite being with
reasonable specifications for the
period it was introduced. Nevertheless
with XRoar you can experience the
Dragon computer and tinker with the
software available for it.
The Amiga version uses ASL file
requester for the selection of the
virtual diskettes, cassettes or
cartridges. There are 3 video modes
available for selection. The YUV
overlay video output mode displays on
resizable window, which can be used
directly on Workbench. The emulator
supports Joystick via Amiga Input,
have sound output and recognises
several formats for diskette images,
snapshots and tapes. XRoar is a new
development, under constant updates
but is available already for GP32,
Nintendo Dual Screen, Linux and PSP.
The Amiga version contributes to its
wide availability. Because of legal
reasons the original firmware ROM
images are not included in the
archive, but only a freeware
replacement with very limited
functionality. The replacement gives
the possibility to load software,
without the need of original firmware
ROM image files. If you don't have any
firmware images, you might like to try
this one. It doesn't do anything
beyond trying to boot OS9 (Dragon
version), and only a few cartridge
images work with it (mostly CoCo
software - Dragon carts seem to always
contain many more direct jumps into
ROM). If you do have images, but want
to try this one anyway, save it out
and use "-extbas FILENAME" to load it
instead of the normal Dragon 64 image.
Popular software titles for the Dragon
computers include games
- Manic Miner,
- Frogger,
- Chuckie Egg,
- Jet Set Willy,
- Donkey Kong,
- Cassette 50,
operating systems
- OS9,
- Dragon DOS,
productivity software - Dragon Graphic
Studio,
- File Master, Rainbow Writer,
- 6809 editor assembler.
There is software for Dragon in the
Others section. Not being that
popular, nevertheless, the XRoar
emulator providing Dragon emulation
with enhanced functionality compared
to the other Dragon emulators for
Amiga, gives great entertainment for
the people enjoying the retro
computers and the software written for
them.
