Got it. Emulation works using SB16+LAPC-I. LAPC-I emulation sounds great as always. SB samples looks very low quality but works. I'm afraid you will not get better sound quality in this game.

It looks covox voice master/sound master for PC does not use LPT port but 220 port so it must be a internal ISA sound card. However covox voice for atari continues to be LPT port device.

This patch emulates raw DAC on LPT. If any game does some kind of autodetection by sending special codes and listening to special answers it will not work. If somebody knows such secret codes there is room for improvements. I checked Pinball Fantasies in covox mode - works.

Nice! Good work! Cool Thanks :happyhappy: There is still missing support for stereo on LPT. I do not know if any game makes use of it. If not there is no need for digging support for it. I found so far 4 types of stereo on LPT: Method 1: 2 DACs on 2 LPT ports = 2 channels = stereo (which LPT is …

I've just downloaded cvs and built dosbox with debug option. However can not see messages returned by LOG() and LOG_WARN() functions. How to enable logging for disney.cpp operations? Is any way to capture data at 0x379 and 0x37a ports?

Recent CPUs have built in Virtualization feature for better performance of OSes executed in parallel: http://www.intel.com/technology/computing/vptech/ Will dosbox use such feature to improve emulation performance?

Modern mainboards with no ISA slots sometimes can not emulate ISA sound on PCI soundcard. That was in my case. I had 2 mainboards: Abit NF7-S 2.0 (no ISA, nForce2 chipset) and Lucky Star K7VAT+ (1 ISA slot, KT133A chipset). SB Live! and Audigy in pure DOS with special driver works great in SB16/ …

If you want CM-32L emulation with munt and have ROM files do not rename anything. Just copy CM32L_* files to windows/system32 directory where MT32* files are already. Munt autodetects CM32L_* files and use them instead of MT32_*.

Does dosbox support LPT soundcards in stereo? I found information that stereo LPT sounds was done in 2 ways: a) two LPT ports with two connected DSS b) one LPT with one DSS. The left/right channel switching is done via signaling on pin #1 of LPT port - the STROBE signal.

I completly have no idea whats up with this game in linux. All other games works and desert strike works in windows XP. Maybe this 1994 dated DOS game requires WindowsXP to run 😀

Another game which hungs in linux is Sid Meier's Colonization. But this game has install.exe. Using install.exe I set 'no sound' to audio and midi - after saving this settings colonization runs OK. Desert Strike has no external install.exe - the sound can be disabled in game - but this is too late. …
