VSBHDA

Sound blaster emulation for HDA (and AC97/SBLive); a fork of crazii's SBEMU: https://github.com/crazii/SBEMU

Works with unmodified HDPMI binaries, making it compatible with HX.

Supported Sound cards:

• HDA ( Intel High Definition Audio )
• Intel ICH / nForce
• VIA VT82C686, VT8233/35/37
• SB Live/SB Audigy

Emulated modes/cards: 8-bit, 16-bit, mono, stereo, high-speed; Sound blaster 1.0, 2.0, Pro, Pro2, 16.

Requirements:

• HDPMI32i - DPMI host with port trapping; 32-bit protected-mode
• HDPMI16i - DPMI host with port trapping; 16-bit protected-mode
• JEMMEX 5.84 - V86 monitor with port trapping; v86-mode

VSBHDA uses some source codes from:

• MPXPlay: https://mpxplay.sourceforge.net/, for sound card access
• DOSBox: https://www.dosbox.com/, for OPL3 FM emulation

To create the binaries, Open Watcom v2.0 is recommended. DJGPP v2.05 may also be used, but cannot create the 16-bit variant of VSBHDA.

In all cases the JWasm assembler (v2.17 or better) is also needed. For Open Watcom, a few things from the HX development package (HXDEV) are required - see Watcom.mak for details.
