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:
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.
