v1.7

• fixed: clear CF in case int 31h hook proc handles the function (ax=0x20x).
• added soundfont support from VSBHDASF; new cmdline options /SF, /MV, /PS.
• fixed: array bounds check in vopl3.cpp added (& 0xff).
• fixed: handling of DSP cmd E2 (DMA identification).
• DSP cmd 14h with size < 32 will trigger an IRQ at once; this should make
  more detection routines to work.
• qpiemu.dll: bit 1 of register CH now holds IF.
• XMSRes.exe: option -H added.
• SB16: 8-bit signed PCM mode (C6h 10h) supported.
• HDA: reset controller if no codecs are attached.
• cmdline option /CF added.
• fixed: ES1371 audio driver.
• /F cmdline option now accepts 11025 as argument.
• added support for SiS 7012.
• cmdline option /O1 for SBLive enables speaker jack.
• fixed: SB Live/SB Audigy FX8010 initialization.

v1.6

• fixed: some port trap variables weren't initialized if real-mode port
  trapping was disabled.
• fixed: debug displays may have caused a GPF.
• VSBHDA16: option /DIVE added; enable Borland "Runtime error 200" fix.
• fixed: VPIC EOI check now tests bits 5/6 of OCW2; handles specific EOIs.
• fixed VMPU: set UART mode cmd 0x3F added.
• fixed regression v1.4-v1.5: if DAC had no amplifier, volume was very low
  and couldn't be changed with /VOL.

v1.5

• MPU port emulation if BLASTER variable contains P=xxx.
• cmdline option /P added.
• cmdline option /SD added.
• fix: volume for SB Live/Audigy wasn't set correctly.
• trap PIC port to reject attempts to mask the real sound hw interrupt
  (Rational DOS extender).
• switch to client context for SB interrupt emulation.
• HDA: improved error msg if card init fails.
• IRQ 2 accepted.
• fix: SFX noise in tyrian2k, also may be in other games that use
  non-autoinit DSP cmds.

v1.4

• added 16-bit protected-mode variant vsbhda16.exe.
• reworked HDA initialization code
• Creative's diagnose.exe accepts vsbhda's SB emulation.
• fix: virtual DMA address may have been too high (crash in tyrian2k)
• fix: writes to virtual DMA channel ports C0h-DFh caused writes to
  ports 10-1Fh
• handle "Runtime Error 200" issue in vsbhda16.
• fix: DSP cmd 0x91 now handled correctly.
• fix: virtual DMA register reads of 08/D0 (status) corrected.
• removed stack checks for C++ sources.
• fix: mixer volume setting for HDA devices.
• cmdline option /BS added.
• direct DSP cmd 0x10 supported.

v1.3

• variant compiled with OW 2.0 (vsbhdaw.exe) added

v1.2

• no new functionality
• PCI config space access now with BIOS functions
• ensured that "interrupt disable" flag in PCI config cmd is zero
• binary size reduction
• Jemm & JLoad binaries removed - the official Jemm package v5.84+ will now contain the appropriate versions.

v1.1

Fixed: trapping PIC port 0x20 wasn't implemented correctly, resulting in lockups on some systems.
