Do you a screwdriver to hammer in a nail? Plain and simple, Dosbox is not the right tool for your particular use. It may work to some degree, but the authors have repeatedly stated their intent and direction with the code, and it's not what you are doing. There are a variety of free, even open …

Unfortunately this has always been a weak spot for SDL (in fairness, SDL was released before it was anywhere near common to have two monitors, and DirectX didn't even support an exclusive framebuffer on the second monitor at that time). I don't think it works in 1.2 regardless of settings. It's been …

I've tried to change configuration, but nothing changes. Ok, but what exactly did you change? The most helpful thing would be to try different output= options and see what happens. surface, overlay, opengl, ddraw. If you've tried them all and none work, let us know. -Frob

No, Dosbox doesn't implement network redirection of a printer. You would be much better off for such tasks in using one of the virtual machine environments like Vmware or VirtualBox. Dosbox is intended as a simulation that allows you to run DOS based games, not a true recreation of all of the …

Usually means that vsync is turned off in your video driver. You can try different output= options or look at the options for the video driver in windows. Try opengl, it's slower for some cards, but for pretty much any of them they vsync when opengl is active. -Frob

I got it to compile, but if I try to run it, it needs "libpng12.dll" and "zlib1.dll." The official PNG and ZLIB sources have issues like this when compiling with the Visual Studio projects and have for some time. It's a straight out bug, which I reported upstream long ago, but not many people use …

DJ, the point is the authors can't support old versions because the code base has changed so much to increase performance/accuracy. You've already demonstrated for yourself that DosBox is not the cause of the actual error. When you run in safemode, DosBox is executing all the same code, just using a …

As for speed, compiling DOSBox yourself on Visual C++ Express 2010 with full-program optimization (and all other optimizations that make sense) does give a nice speed boost, if you can pull it off. Really? Can you provide examples, because since the dynamic interpreter DOSBox has been very …

You might try VMWare, which I know other folks have used with hardware dongle devices before successfully. The player is free, and as long as you have a copy of original DOS around (which the app might be picky about anyway!) you'll be all set. Or you can try Freedos under VMWare if you can't find a …

Regarding my earlier questions - I wrote the save state for the Atari800 emulator, and a couple of others. Basically you are interested in saving everything that may be read in any form later - while I'm not aware of any DOS programs reading the sound card buffer, if it ever happens, that game will …

A modification that might work is leaving as is when the render framebuffer is less < 4x the area (or < 2x in each dimension) of the original, but otherwise making aspect true. It looks fine once you've got enough surface area for filtering to kick in, but it definitely looks ugly when you have no …
