I have created a version of Wolf4SDL that now has PC speaker emulation based on the code in Chocolate Doom.
Could people please test it and tell me what you think (bugs/issues/suggestions etc.)!
If it works OK I will see if I can submit it to the Wolf4SDL author (as this feature is on his TODO list).
Also anyone know if the Wolf4SDL guy is still around? No updates to his website since 20008...
Otherwise I might create a fork on Google Code where people can implement any bug fixes/tweaks/features etc that they want in the codebase...
Here is the compiled file: (built for Activision Wolf3D)
