That's good insight, I did test that command but not in this context. I look forward to testing your results.

I'll let the experts decide the rest. I wanted to tinker just a bit further because I had some ideas to test.

I didn't mention earlier, but opencp doesn't work (so far for me) in XP ntvdm. I went over a dozen code samples using auto-init dma and some of the corresponding binaries show the same issue as q2dos, even though the code is short. I think ntvdm dpmi is not made for sound compatibility. 😀

I spent a lot of time reading about these parameter settings, but there is too much conflicting information. Instead, I experimented with them since the examples are lacking.

The only change should be disabling extra functions in makefile (but for cd audio). I will run a difference file between the entire source from your branch and the modified one, although I don't recall other changes. Edit: just realized I changed settings in the ms dos box in 95 (such as fast paste …

It's my pleasure, especially give your team's efforts in bringing us the port.

The directory /wattcp/bin/ has wattcp.cfg. Placed this "watt" configuration file in the directory along with q2.exe and modified settings. There is even a setting: pkt.near_ptr = 1 ; optional (djgpp only). It also has settings for logging to a file.

I like the enhanced R_DrawParticle function. Would it further help (avoiding function calls) to inline the other vector math functions (dotproduct; vectorsubtract), too? This appears to be a change from the original snd_dma.c code: // mix ahead of current position endtime = soundtime + s_mixahead-> …

There are reports that vdmsound has issues after XP sp1. I don't have an early version of XP, but that should be a better test system toward ntvdm compatibility. However, it is worthwhile to verify and document the audio code.

Thank you for the information. The decreased buffer size allows Quake 2 to report sound initialization without error, but there is not yet output of sound via the ntvdm. However, I haven't tested on another system. Perhaps vdmsound would now work.

Attached two patches against a recent version. Patch #1 activates a minimal build for use in NTVDM. To test, here are potential command lines to run Quake 2: q2.exe -skipwincheck -nosound +set sw_mode 2 q2.exe -skipwincheck -nosound +set sw_mode 1 q2.exe -skipwincheck +set sw_mode 1 With sound …

If setting "USE_CURL=0" in Q2Dos makefile, then there is a TCP/IP Segmentation Error in XP NTVDM. The error does not occur where "USE_CURL=1". From limited testing, this is independent of the other makefile settings. There may be leftover dependencies on the CURL library where building without it.

It works in a 95 dos box with the parameter -nosound, too.

It opens the possibility of linux/dosemu as another host for Quake 2. It also tests "corner cases" as TheGreatCodeholio has done with demos in dosbox-x.

I haven't encountered any strtok related errors in-game. Perhaps the mod authors could find this information in the "mod porting" guide enclosed with q2dos? The strtok change (and others which relate to mod porting) could be documented to make the porting effort easier for others. I tested Quake 2 …

I'll try to release a binary for testing in ntvdm which isolates the NT friendly (video) code. There is a note by "TheGreatCodeholio" about ntvdm sound emulation and the dma buffer size. This is one area to verify in the Quake 2 sound code. The d_part* assembly code from Quake 1 may port more easily …

This works in XP NTVDM: q2.exe -skipwincheck -nosound +set sw_mode 2 Requires a .PIF file where "Fast pasting" is turned off in "DOS" property sheet. Uses 640x480 banked mode. Sound not working yet (tried -dsp 2), but vdmsound and gusemu is worth testing.
