I extracted the SB_x.MNI files from NUKEM2.CMP.

But now i need a comverter that can convert Sound Blaster ADPCM VOC files to Uncompressed PCM VOC files.

Can somebody help me. This conversion should fix OPL-SAx and other Clone card issues.

Or maybe someone has allready done such a conversion.

I am aroused about any X86 motherboard that has full functional ISA slot. I think i have problem. Not really into that original (Turbo) XT,286,386 and CGA/EGA stuff. So just a DOS nut.

SB_x.MNI files are standard Sound Blaster VOC files, and few of them are compressed with Sound Blaster 8-2 or 8-3 ADPCM codec, but Duke Nukem 2 can play 8-4 ADPCM and uncompressed PCM files also. So you just have to convert them, and then leave those converted files in Duke Nukem 2 directory, and it will use them. The point is that Yamaha OPL-SAx do not play 8-2 and 8-3 ADPCM files in hardware, but Duke Nukem 2 is one of few games that relies on full Sound Blaster hardware decompression.

I believe old versions of Cool Edit are able to open SB ADPCM .VOC files, might be able to save as uncompressed. Why don't you give it a try?

I ask and I answer, i used Blaster Master 6.2, it is a dos sound program. Only it can not open 3 files, i think because they are too small, but those files are not compressed, Because Audacity does open them, and plays them. These files are SB_17.MNI SB_19.MNI and SB_22.MNI. All else i converted and uncompressed. Now everithing woks with external files, now i am trying to incorporate the new files to NUKEM2.CMP.

Well i am a fan on Duke Nukem 2, and i do have 4xOPL-SA3 (3 of them with wavetable headers, and they do not have a hanging note bug) based sound cards, so i just started doing things.

Do any other game have that same ADPCM (2-8) (3-8) sound output issue?

By the way, I'll have to check my SB Pro V2 software. I seem to recall it had some software to record, compress and play VOC files, including ADPCM ones. Might also have a decompressor in there.

Wow just wow, I can't wait for this! Didn't even realize it was a thing until I tried playing my beloved Duke Nukem 2 on newer hardware.

Yes, my work computer does not allow to install new software, but i got a portable dosbox, and portable Duke2Edit, but no portable Camoto, so i e-mailed my project files to myself, and if i have time in home, then i will try to repack NUKEM2.CMP.

I extracted the files into the Duke Nukem 2 directory, but I do not get any audio output.

I use Dosbox Megabuild6 in Win98SE for hardware OPL output on a Yamaha YMF-744.

Duke Nukem 2 will not allow me to enable soundblaster or adlib with oplmode=hardware in the dosbox config.

The Duke Nukem 2 I am using is from GOG.

I am not familiar with that kind of a setup, but in a real PC with OPL-SAx, originally you get sound effects, but only few of them, but with these files, you get all sounds.

Thanks for this! I'm going to try it out when I get home. As you may know, I have one of the Yamaha Audacian Plus 32.

Should I try this with disabling L1 cache, or just leave everything full speed? I know disabling L1 cache did fix the sound issue at the intro, but not all sounds were still playing in-game. Also disabling L1 cache is too slow for actual game play. Disabling L2 cache doesn't fix the intro sound issue either. (PII-400 and P3-650).
