Interesting project, thanks for it. This gives hope to add protected mode support to SoftMPU , but the damn differences in GNU-syntax here and the intel-syntax in SoftMPU will cause a lot of code redoing... This project is not built in Watcom compiler because HDPMIPT.C has a lot of inline code in …

Excelent! It would be cool to add support for MPU-401 from this project: wolfmidi+wolfdosmpu - Wolf3D/SoD music in General MIDI (fully-automatic converter) + WOLF3D.EXE with MPU-401 support

SF2 support would be amazing though There is nothing difficult in SF2 support, it is enough just to replace the SBK pawe32.lib library from the Creative development kit with another one with SF2 support. I even tried this and it works without breaking existing code or breaking sounds. But there is …

Out of curiosity, I disassembled the C4502_C1 file and did a quick and dirty hack to read dumps from AWE eeprom. So the AWEDUMP v0.1 utility is here. Runs without parameters and tries to read the EEPROM contents. Creates an AWEDUMP.BIN file on disk in current directory if successful. Attention! …

Uhhh really interesting!! With two SAA1099 chips available maybe it's possible to use one for sound effects (mono) and the other for music although with only 6 channels available. The mono CMS PCM is already available since I programmed it first, and then added stereo support. Hmmm, i have the same …

And now MP3 to WAV simple decoder for [XT][8088]. I used Helix mp3 decoder from RealNetworks. I made changes to the assembly.h file (rewrite MULSHIFT32(), MADD64(), SAR64() in 8088 assembler).

Okay, found WATTCP library source code here: http://www.jkmicro.com/Downloads-TCP-IP.html I also recompiled them for the 286 processor and rebuilt the program again. Since I cannot check whether the TCP/IP stack will work at all after this, I will leave both versions (message earlier and this).

I looked at the source code v1.99 and didn't see heavy use of floating point math. The only place where it is used is the arc drawing procedure in the LOPIF library. The project also uses the WATTCP library, but I did not find its source codes, only pre-compiled .LIB file included. In any case, I …

So how does 'CGA Redux' deal with this demo? if the question is for me, then i can't say exactly. I don't have a real 5150, I just have different kinds of XT-clones motherboards. I also do not have a real CGA monitor,so to display the image from CGA i use the MCE2VGA converter. I tried to run the …

Is that snow static, or does it flicker? A small video might be nice. Something like this: https://youtu.be/0ivcM-2TK4w Also: where die you get the CGA Redux card from? Looks neat!
