Sound emulators don't work with NTVDM

[WindowsNinetyTen]

After installing VDMSound and then trying to open a progam with that, I just get a "bad command or file name" message. Why is this?

And also, for SoundFX, I can't use it at all, because it's a "time-limited" evaluation version.

Did you even read their homepage?

There is a .reg file that disables time limitation right on the download page.

This version works fine here.

Yes, I did read their homepage and tried to apply the fix. But I still got the "time-limited evaluation" message even after applying the notime.reg file to the registry.

I tried the file which you posted, but even that still gets the "time-limited evaluation" message.

The Source Code sbvdd.c

/*

• Start evaluation timeout
  */
  extern void StartEvalTimeout( void)
  {
  static MMRESULT s_hTimer;

TRACE( 9, ("StartEvalTimeout()\n"));

if ( !s_hTimer)
{
DWORD dwTimeout;

/* Start the evaluation timeout */
dwTimeout = 3 * 60 * 1000;
s_hTimer = timeSetEvent( dwTimeout, 1000, &EvalTimeout, 0, TIME_ONESHOT);
if ( !s_hTimer)
  {
  TRACE( 0, ("!!! StartEvalTimeout() timeSetEvent failed\n"));
  /* Immediate timeout */
  EvalTimeout( 0, 0, 0, 0, 0);
  }
else if ( ReadRegValue( "PSQR@+,<", REG_DWORD, sizeof( dwTimeout), &dwTimeout)
  && 0x19541009 == dwTimeout
) {
  timeKillEvent( s_hTimer);
  }
}

}

The reg file:
REGEDIT4

[HKEY_LOCAL_MACHINE\Software\SoftSystems\SoundFX]
"PSQR@+,<"=dword:19541009

Recompiled sbvdd.dll free build for you, this one should work out of the box (replace it in your SysWOW64 directory):
sbvdd.zip

[leecher1337]

Btw: Reg-file probably doesn't work because it must go to WOW64 node on 64bit machines (NTVDM is 32bit application):

REGEDIT4

[HKEY_LOCAL_MACHINE\Software\WOW6432Node\SoftSystems\SoundFX]
"PSQR@+,<"=dword:19541009

notime.zip

sbvdd.zip WORK.
notime.zip Failed.

The sbvdd file worked and the problem is now gone. Thanks for your help!

[peter8777555]

It seem do NOT support Ad Lib ??

[leecher1337]

Which application did you try with? Also did you set FM Synthesis to emulation,because most PCI hardware soundcards don't prvide AdLib support.

Please refer to the Sample.zip for more details.

I found out that there are some weird issues with SoundFX and NTVDMx64. If it is enabled, some applications tend to hang on startup sometimes. As soon as SoundFX is disabled, applications work fine again. Not sure, if this is a bug in SoundFX2000 or NTVDMx64.

It's been some months... Have you been able to figure out where the bug is? (I'm just curious BTW)
