Re: 32-bit OS that will run best on 8MB 386sx-16

A downside is the device driver availability in OS/2 2.x (versus Microsoft Windows 3.x).

It may not be reproducible, but where a large time delay occurs at startup (such as loading cd audio), then sometimes movement of the parent window before the shell loads will lead to a sudden exit.

That's exactly what I tried. I tested your code with DEBUG lines active. It is thorough and allowed for evaluation of End of File for a non-file based cue/bin pair (along with eof versus general fail bit error checking). I hope to eventually test your emulation with cd audio at a lower rate on the …

I wonder if there is a list of redbook audio DOS games with any playback by redbook offset instead of by track. Is it also possible to efficiently log the event as a warning along with some data? I've also been testing and logging on the redbook audio functions - thank you for the continued …

One problem of supporting several compilers is the vast amounts of regression testing. Every version is different.

Is it possible to attach two soundblaster devices for use by Sequencer Plus Gold? The software supports multiple soundblaster cards by loading its FM synth driver, SAPIFM1, twice. Here is an example: SAPIFM1 /ADDR:230 /PORT:3 SAPIFM1 /PORT:2

The D4V gameplay mod (DOOM 4 VANILLA v2.2) exits with error while playing map06 with DIGMID wavetable music driver. Did not yet detect this issue with other midi based songs. One solution is to convert the MIDI lump to a MUS formatted lump file. Have not yet determined the cause in the code, but the …

The ideal solution has the least dependencies on a particular platform while having sufficient performance. The DOSBox method fits this better than the alternatives, although boxedwine has potential if it ports easily to non-sdl2 platforms and the interpreter cpu emulation is sufficient. For Windows …

It is from: https://sourceforge.net/projects/hx-dos/files/2.17/ May start with that version 2.17. The file is archived in HXRT217.zip as HDPMI32.EXE. (I previously pasted the name incorrectly as HDMI.)

Amiga sdl1 ports may be a possible source for that OS, although the memory limit is very low. Perhaps an older doom source port would work, such as an earlier zdoom version which is dependent on sdl1 for the software renderer and audio with an option for opengl rendering. It should be tested first …

For a working performance comparison to the original x86 dynamic core. The result was unexpected since the relevant changes are not many.

Verified that the r4252 commit is present. The 32-bit build works now, but by undefining X86_DYNFPU_DH_ENABLED and using a non-x86 fpu interpreter core instead. It runs significantly slower in this non-standard configuration than the previous dynamic x86 cpu core in 32-bit Windows. It seems that …
