The final command that once has to place in DOSBox autoexec. The PC Speaker emulation is way louder than the rest, so a good value after careful testing is 25.ĮDIT: Adjusted in the latest SVN, no need to change FM volume, keep it 100. To have a realistic balance between FM and PCM one has to set FM in DOSBox mixer to 75. Then after careful listening with various games I found an output value for dosbox to be in balance with SC-VA and a real SC-55.įor DOSBox to have the perfect mixer balance between SC-VA and its output, one has to set the Master in DOSBox to 50. To calibrate volume balance between a hardware SC-55 and SC-VA I used a midi file (attached) I created to adjust the output between them. To measure the dB balance between PCM and FM with a real SB card in DOS I had to run a sinewave test tones for the PCM and FM using various DOS programs and measure the difference between them in dB, I did the exact same procedure in DOSBox.ĭOSBox FM was around 2-3dB louder than with a real SB cards (SBPro,SB16,SB2.0). Loads the configuration file from the users profile or home directory. BAD Go into nf and make cyclesmax, and save. Starts DOSBox-X without showing its GUI menu. Iirc, it set cyclesauto, and that just plain makes everything stutter and lag and music choppy. You will also need to mount the Windows 98 CD-ROM. First mount the harddisk image you created earlier: IMGMOUNT C hdd.img. Useful for specifying particular options for specific games. This assumes you have already started DOSBox-X with the nf config file and created your harddisk image. This is the default behavior, so this switch is useful when using -conf, below.-conf configfilelocation Load the config file specified in configfilelocation. conf file can get loaded automatically depending on the Emulation > Loading of nf core option. Starts DOSBox in fullscreen mode.-userconf Load the configuration from the users profile or home directory. If you are interested in the procedure go to this thread: FM and PCM Volume Balance of SB Cards 0.70, I had to go into START, ALL PROGRAMS, DOSBOX 0.70, nf, and edit that file so that cyclesmax. conf file gets selected in the frontend, DOSBox Pure will mount the directory of that file as the C: drive and then use it. If anyone care about sound here are some results after careful measurement and comparison with real SB cards and SC-55.
