There are two Windows multimedia frameworks: Video for Windows and DirectShow (used to be ActiveMovie). Video for Windows dates back to 1992 and DS to 1996. Both are supported in XP. ZMBV is a VfW codec and VirtualDub is a VfW application (DirectShow uses "filters"). It could be that Vista has …

Virtualdub can open Dosbox videos as long as the ZMBV codec is installed - no need for ffdshow. The codec is located in dosbox\zmbv (right click on the .inf and Install).

I have many games which if I do not explicitly enter a resolution like 1024x768 or 1920x1200 the game will not fill my screen. I misunderstood you. I thought you always wanted a correct aspect ratio (i.e. black bars) instead of filling the whole screen. Dosbox will consistently give you a correct …

I just find it odd that some games will respect aspects and others not, regardless of dosbox's aspect= setting. There has to be a reason. aspect=true only affects game resolutions that have a vertical dimension of 200 or 400. If aspect=true, then those are corrected to 4:3. Beyond that, Dosbox …

Does DOSBox offer support for a 4:3 letterboxed display on widescreens, and how can this be done? Set output=ddraw, fullresolution=1680x1050, and aspect=true. Everything except text modes should then have the correct aspect ratio and fill the screen pillarboxed. output=ddraw enables hardware …

If you've set fulldouble=true and aspect=true, try setting either one or both to false. That particular combination (both true) corrupts Dosbox fullscreen graphics on my laptop with an S3 video chip.

I just tried the shareware version of Blood on my AMD Athlon XP 2400+ at core=auto, cycles=auto and it ran smooth as butter at 320x240, quite fine at 640x480 and it was even playable at 1024x768!

Just setting the fullscreen resolution to your display's native resolution (as long as its pixels are square) and setting aspect=true should do the trick. I just tried it and a 320x200 game gets letterboxed (small black bars) correctly at non 4:3 modes. At fullresolution=1280x960 it of course covers …

"The reboot did it. Thanks! but I don't understand." Some program (that's running in the background for example) opened the file and didn't close it, which is why it says access denied. The culprit is often a Shell Extension (they add custom views of different types of files to Windows Explorer for …

It's a cheap Dell USB mouse. I also tried with a Logitech PS/2 mouse, but no change.

Changing the priority had no effect. In fullscreen sensitivity just drops to ~50% of what it is in windowed. Not skippy or stuttery at all, just a lot slower. For example in Dark Forces I can spin 360 degrees without lifting the mouse from the pad in windowed, but in fullscreen the sensitivity is …

Hi! Mouse sensitivity in Dosbox seems to differ between fullscreen and windowed modes. In fullscreen mode the sensitivity drops considerably. This happens on both ddraw and surface video output drivers, and different resolutions in fullscreen and windowed modes don't have any effect either. It …

where is this double scan feature ive never seen it In NVidia's control panel under Display Mode Timing.

1.) Must use patched VGA.SYS for NVIDIA video adapters to get beyond VESA mode 0x101 (640x480x256color) and find way to prevent the WinXP file-protection system from restoring original VGA.SYS file. 3.) Must use MOUSE2KV.EXE to execute CDSHOCK.EXE with parameters properly set for desired playing …

Sorry to bump such an old thread, but I'm interested in knowing if anyone has recently been able to run Tie Fighter Collector's CD-ROM (DOS) with General MIDI music. It seems that the starter of this thread was able to, over three years ago. For the past few hours I've been trying various …

Hello and thank you for this great emulator! I installed the GUS drivers according to the 'GUSPatches' page on DOSBoxWiki. I get to the point where the installer starts "Configuring MIDI Directory". It seems to scan my directories in the C root (I installed the GUS drivers to the default c:\ultrasnd …
