Let me just confess that I have such a multi-faceted life these days that I spend little time on fractint, probably less than most people on this list. But today I'm home from work early and have a little time so I rediscovered some work I did late last year. On my Windows 7 64 bit system, I have the DOS fractint in c:\fractint. I have two versions of DOSBOX, the official one 0.64, and an enhanced "svn" version, that is both built off a non-released DOSBOX subversion code modified with unofficial features. The "SVN" DOSBOX looks to be far better than the official one for our purposes. Here's where I got DOSBOX: http://ykhwong.x-y.net/xe/dosbox_data/143 And download the 7-zip file in the blue box: 20120220.7z Unpack this into a directory of your choice. I edited the file dosbox.conf, and added some lines on the bottom to make my fractint directory visible (modify to match your fractint setup): [autoexec] # Lines in this section will be run at startup. # You can put your MOUNT lines here. mount c c:\fractint c: fractint Then just execute from a file manager: dosbox.exe and Fractint comes up. What I love is that the high resolution modes work in this DOSBOX version. They don't seem to in the stock release. I edited the SF10 mode in fractint.cfg like this to get 1600x1200: SF10,VESA Standard interface ,4f02, 120, 0, 0, 28, 1600, 1200,256, DOSBOX Even color cycling works! I'd be curious to know how others are doing under Windows 7. Tim

There are two other lines in dosbox.conf that I edited: frameskip=5 and cycles=max These two lines let fractint run much faster. Tim
Hi Tim, Good to hear from you. DOSBOX works fine for me in Windows 7 64 bit. I have not tried the svn version. All the VESA video modes work for me through 1280x1024x256 in regular DOSBOX. However, your 1600x1200 mode does not. I guess I'll have to try the svn version. I also set cycles=max which speeds it up. The DOSBOX docs have some warnings about this but I don't see any negative effects. DOSBOX seems to never take more than 13% of the CPU even when it is calculating a fractal. I do not see that frameskip has any effect. You can set frameskip on the fly by using Ctrl-F7/F8 but I don't see any difference in speed. BTW, my system is a laptop with Intel Core i7-2630QM (2.0 GHz). Nick On 5/10/2012 1:05 PM, Tim Wegner wrote:

rediscovery of ancien fractal work done with fractint is marvellous for the inner_self constant use, i feel like i leave joy pass by.. will test new dosbox parameter soon with windows xp and strange videocard ati... let you know, the fractal result is different.?!? ancien tiger faces show last use but the computer is now off in travelling car. i keep this msg in mind.. or re_pass.? more or less a month... OUf for windows 7(seth) this dos box in prodjection 0.74, only sad point it do not compilate old ansi code nd straight dos freeze with tera_disk, buzz issu.or tank's?!?! 2012/5/10 Nick Grasso <nick@nickgrasso.com>
