There's a new version (0.65) of Dosbox out:
http://dosbox.sourceforge.net/
I've tried it, and it fixes all the most important bugs that bugged me
in previous versions. Definitely a vast improvement.
It is now good enough to enable Windows XP users to satisfactorily use
the DOS version of Fractint.

There are still some efficiency problems, but hey, it WORKS now!

Okay, it's confession time... when I need to run MS-DOS, which is admittedly
rare nowadays, I have a perfectly satisfactory Ancient86 with MS-DOS
version Dinosaur.0 (5.0, I think) running quite happily thereon.
And when I don't need to run MS-DOS, well, obviously I use Linux. :-)

Well, good to know. I'll download it whenever I realize 0.63 isn't
sufficient anymore. But for now I'm quite content.

_Some_ efficiency problems, he says! Fractint runs fine outside DOSBox
for me, under XP. The only problem I've found is that I can't use
graphics modes larger than 640x480. However, even at that resolution,
the default, minimum-zoom, minimum-limit Mandelbrot takes all of 13
seconds under DOSBox. Direct under XP, it is virtually instantaneous
for, at a first try, 11 complete zooms, with as high a limit as I need.
(After that, it starts needing its bignum library, which gets pretty
slow pretty fast even without DOSBox.)
Since fast number crunching is the one thing you need most when you
compute fractals, and you can use a mediocre display to pick the right
one, computing the final pretty pictures on disk only, I don't think
I'll be using DOSBox for Fractint.
I do, however, have several old text adventures which run sluggishly
under XP's (intentionally?) slightly wonky DOS text mode emulation, and
even a couple which won't run at all. For those, DOSBox is ideal. That
it's not as nippy on the computation as the whole computer really
doesn't matter much if it spends 99% of its time waiting for you to
press the next key, anyway.

Under plain XP DOS, I can't use graphics modes larger than 640x480x16.
You can't do anything remotely interesting in Fractint with 16
colours. And as for the resolution, I have a bunch of saved 800x600
Fractint images already, and don't see why I should settle for
anything less.
With 16 colours, you can't even get decent milage out of the + key.

How can you tell it's the right picture if you can't see it? And what
good are pretty pictures if they're nothing more than abstract
computations on a disk?

For me, the efficiency contrast is less extreme.

Whereas I can get to any number of colours (though more than 256 are
relatively un-useful), as long as I stay within 640x480 pixels. VESA
autodetect works fine.

Ah, that's a different matter - that means you can use _those files_
satisfactorily, not Fracting /per se/. Which, I agree, is a good point,
but only for those who already have such files.

You can decide what area you want in the low-res (but medium-colour)
mode, and then compute the final image in disk mode. Since they're
ordinary GIFs, the end result can be viewed using any good graphics
program.

So Windows XP behaves differently on different hardware, and so does
DOSBox. I'd like a show of hands: anyone surprised? Nobody? I didn't
think so.
My experiences with these programs are hardly universal, but neither are
yours.

Folks using DOSBox for old games may also want to consider d-fend
(http://members.home.nl/mabus/dfend.htm) which makes it far easier to
use.

Personally, I have no need of a frontend, because all my DOS programs
so far work just fine under identical settings, so I don't need to
change settings depending on what program I'm using (the main
advantage of a frontend is that you can do this).
My DOSBox customisations are as follows; otherwise I use the defaults.
fullscreen=true
core=dynamic
cycles=5376
cycleup=128
cycledown=128
mount f c:\fractal
mount g c:\games
mount q c:\programming\qbasic
mount u c:\utilities\dosutil
Just for interest.
Adrian.
