With SDL 2.0.6 onwards, the audio doesn't work when running on Windows. This is because newer versions of SDL use WASAPI by default. DOSBox uses signed 16-bit samples for mixing, which DirectSound and XAudio2 were fine with, but WASAPI insists on using 32-bit floating point samples. DOSBox does not …

Out of curiosity, I tried using this line and it compiled successfully: static char string_productrev[]="DOSBox ""SVN"; For some reason, the preprocessor doesn't want to convert VERSION into "SVN" unless there's a space; I'm guessing it assumes it's a suffix and leaves it alone, which causes the …

I've just built DOSBox with Visual Studio 2015, and it appears to be working okay so far. However, there were a couple of things I had to do in order to get it to compile that weren't required in previous versions. First, the new compiler doesn't like the following code at int10_vesa.cpp, line 48: …

Finally got around to creating a diff file with the changes, compatible with SVN r3923. Also posted on SourceForge.

When running DOSBox with EGA emulation, many of the BIOS video modes have incorrect horizontal and/or vertical totals. Modes 6 and E have what appears to be double the horizontal total of modes 4, 5 and D (120 compared to 60), but the stored values are 3 clocks higher than the actual horizontal …

Ah, I've just discovered what was causing my version to not work. I had changed the line "if (player.ctrlUsed)" to "if (player.ctrlUsed || 1)" to test the effect when CD audio plays at full volume, back when we still had the "divide length by 2" issue. And I had simply forgotten to change it back. …

I changed the appropriate lines, and it now works perfectly. Funny how one tiny number can cause such an annoying problem. EDIT: I've just discovered a bug where the audio plays at zero volume until the ChannelControl function is called, which would be a problem for any games that use CD audio but …

I think your patch is probably as good a solution as is possible to this problem. However, I've encountered a weird bug: The extracted audio samples are not scaled properly, e.g. setting the audio volume to 10% actually results in it being scaled to 1%. However, tiny parts of the extracted sample …

Ah yes, I developed that patch on SF.net after getting fed up of hearing both musics in Pinball Illusions at the same time. It is indeed a bit of a hack, but I didn't feel up to implementing a proper solution at the time. A proper solution would involve controlling the audio extracted from the CD or …

Right, from what I can gather, it is the games, not DOSBox, that are setting up these weird screen modes. So I now think that probably the best way to get around these is just to go with the cheap workaround, at least with the Fantasies sidebar and the Illusions intro. Thanks everyone.

With the SVGA modes in Pinball Illusions, it's not so much of a problem, the game looks and plays fine. Just so you know, what I actually meant is that I would have expected there to be black borders on each side, filling the screen up to 640x480 or 800x600. As it is, these black borders are not …

Yes, I've just tried it, it doesn't work. I've tried loads of other combinations, and none of them have worked, so I think it will take more than just a simple config adjustment. Also, my usual settings are: fullresolution=1920x1200 (my native resolution) output=overlay (scales the image very nicely …

I can't help but feel that the way the screen size changes in Pinball Fantasies and Illusions is weird, particularly with Pinball Illusions. The screen resolution changes to an irregular size at each of these moments: 1. Main menu of Fantasies, when the sidebar slides in. 2. Several times during …
