Not sure, I believe the game hangs at start with SB/Adlib sound (per the threads you referenced), it's working fine for me with ykhwong's 20130107 build. I'm guessing it works fine in other recent DOSBox builds as long as GUS sound is selected. Note there seem to be 2 "Gravis Ultrasound" entries in the setup. The first of which seems to work, while the second one results in hardware not found errors, not really clear what's going on with such.

Can you provide some more description of your DOSBox setup, and/or what exactly...
un windows proposing "run" and "quit"
...means, even with the wrong disc inserted I don't think I see anything similar in my game.

Yep. confirmed for 0.73 and 0.74.

Thanks for you answers !

I make the game open but it freeze two second after that.

I just cant do it. I do my best with dosbox since more than a hour but i'm no good at it.
Could you please explain me what you do to make the game works ?

I'm deeply sorry if i make you lose your time. Please excuse me.

You'll need to set...
[gus]
gus=true
...in your DOSBox config, the other defaults should be OK, and select "Gravis Ultrasound" via SETSOUND.EXE. As noted above, there may be multiple such entries in SETSOUND.EXE. Just use the one that works. You may also need the Gravis Ultrasound drivers installed but things seems to work for me without them.

Thanks you very much ! It works. But I still have a few problems 😒

The fullscreen mode (alt+enter) make the image to freeze.
Do I have to mount the 3cd before starting to play ? Because the game just asked me to put the second cd.

Thank you again !

You can mount all three at once and swap between them using ctrl-F4...
imgmount D "<path>\Psychic.Detective.CD1.ISO" "<path>\Psychic.Detective.CD2.ISO" "<path>\Psychic Detective\Psychic.Detective.CD3.ISO" -t iso

Not sure on the fullscreen freeze. You may need to revise some of the fullscreen settings (i.e. output=surface, output=ddraw, etc.).

Sorry but it only mount the first cd (i did it with the iso and with the iso emulate with daemon)

For the fullscreen's problem i tried many thing from the internet but nothing work. (My dosbox freeze when full screen i s enabled except the double buffer, i don't know how to do it)

Thanks again for you help ! ^^

You don't need to use Deamon Tools with DOSBox, it has it's own internal CD emulation.

Yes, i don't use it anymore, but I can't mount the cd. Are you sure there is no error in this :
imgmount D "<path>\Psychic.Detective.CD1.ISO" "<path>\Psychic.Detective.CD2.ISO" "<path>\Psychic Detective\Psychic.Detective.CD3.ISO" -t iso ??

Well you need to replace <path> with the path to your isos. If you did this "can't mount" is not good enough, post the command you entered and the error message.

And don't forget that you need to press ctrl+f4 to switch between the mounted CDs.

As for fullscreen "many things from the internet"? Not needed. Different outputs in the config and you need to restart dosbox of course. AND the latest graphics driver from amd or nvidia (or whatever graphic chips company your card is from) for your card.

keyb fr
imgmount d "d:\psychicd\cd\Psychic.Detective.CD1.ISO" "d:\psychicd\cd\Psychic.Detective.CD2.ISO" "d:\psychicd\cd\Psychic Detective\Psychic.Detective.CD3.ISO" -t iso
gus=true
mount c d:\psychicd

I must be doing something wrong.

The game has some little freeze when the sound is too big or the movements too fast on the screen.

Thanks again for your help, it became even more frustrating to just play the first cd into a small window.

So what error message?

"Using multiple files is only supported for cue/iso images"

I dont remember this message but it must be it.

Well, then rerip your CDs as cue/bin images.

I believe the files are fine, but should be renamed to have only 1 dot (and thus 1 file extension), so that they are properly recognized as being .ISO files.

I just did what you propose (rcblanke) "The image must be on a host or local drive"

Then your path is wrong again

Erf, true. I did it again and the message still the same.
