Believe it or not, we've had posting guidelines always. READ THEM.

OK,

I have VDMSound 2.0.4 with update 1 and LaunchPad. My system is Windows 2000 SP3. It's an AMD XP 1700+ on a MSI K7T266 Pro2 with 256 MB RAM. I use a GeForce 3 Ti 200 video board. The sound is the motherboard built-in, AC 97. The system is divided into sevearl partitions:
D: is the W2k system drive (NTFS)
I: the applications drive (NTFS)
Z: the games drive (FAT32)
VDMsound is installed on I: and the game on Z:

As stated previously several other games work. IOC also works with Adlib only.

The problem is that when I install with Soundblaster and then run the game I get the following error:

INNOCENT - until caught

(c) 1993 Divide By Zero

Unable to install sound driver.
Please refer to manual.

According to the manual this is due to incorrect or missing environment settings:

SoundBlaster
------------
If you choose to run the game with SoundBlaster music and sound effects,
then you will require an additional amount of base memory:
approximately 30K.

In order to hear sampled sound effects with a SoundBlaster
(or Soundblaster compatible), there must be at least 256K
of Extended Memory free on your computer. If this is not
available, then you should choose the AdLib music option
in the SET_IUC program, which will allow you to play
the game with full music but no sound effects.

Your AUTOEXEC.BAT file that is present in the root directory should
contain two lines that define the SOUND and BLASTER variables
(of the form SET SOUND= and SET BLASTER= respectively). The SOUND
setting is the directory which holds a sub-directory that contains
the appropriate sound driver for your particular card. The BLASTER
setting contains details of where the soundcard is located within
the computer hardware. For full details, you should consult your
soundcard manual. Both these variables must be set correctly if the
game is to play sampled sound effects.

Using LaunchPad I set in the AUTOEXEC.BAT part:
set sound=i:\Program files\vdmsound
set blaster=i:\Program files\vdmsound

which is where vdmsound is installed. I now receive the follwoing error message:

INNOCENT - until caught

(c) 1993 Divide By Zero

The game has been terminated because it was unable to open
the file "i:\Program files\vdmsound\drv\ct-voice.drv".
Please refer to manual.

So trhe question is: can anyone hint me howto set those variables (SOUND and BLASTER)

sorry for the previous posting, of course the blaster variable is:
set BLASTER=A220 I7 D1 H5 P330 T6

I also managed to find the solution: I found out that drv/ct-sound.drv was within the game installation so I tried:

set SOUND=z:\games\innocent (the game installation path)

and voila, it worked.

Well there you go. SOUND is not a standard environment variable for DOS as far as I know.

SOUND may not be standard for DOS, but it's pretty standard for Creative's drivers.

Unregistered helped a lot.
The game works with Sound Blaster now.
Though I still don't hear any sound effects during the game.
When I for example turn off music in game's menu the game is completely silent.
It happens with VDMSound, Dosbox, pure DOS 6.22 and even on a 386 machine.
Actually it is the only adventure game I cannot force to work properly (and I have tried quite a lot of them).
Does anyone know a place in game where it is possible to hear sound effects? Does it work for anyone?

problem solved:
better Sound Blaster support

I finally got dosbox to work with soundblaster (I had been using an older version... .60). I still cannot get IUC to work with VDMSound, which I prefer. Any ideas?

ct-voice.drv from:

"Updated DOS Drivers for SBPro 2 (CT-1600) (v1.0) (OLD)" works not only with DosBox but also with VDMSound when it is set to emulate Sound Blaster Pro and Sound Blaster Pro2

"Updated DOS Drivers for SB 2.0 (v1.0) (OLD)" works with VDMSound when it is set to emulate Sound Blaster 2.0

"Updated DOS Drivers for SB 1.5 (v1.0)" works with VDMSound when it is set to emulate Sound Blaster 1.x

(You have to disable EMS in VDMSound)

Unfortunately, no go. I tried all combinations of SB with the ct-1600 driver properly pointed to in autoexec.bat, but still get the 'Unable to load driver...' message. Are there any other non-default settings in VDMSound besides the no EMS requirement? Anyway, thanks for your help. I'll have to stick with DosBox on this one.

this game requires a lot of conventional memory so you can also disable DPMI

I cannot make it work with the VDMSound Launchpad...I still get the 'unable to install sound driver' even with unregistered's instructions. It works with DOSBox, so I am happy about that. Thanks for your help.
