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.
